    The best Fire TV devices include streaming sticks and smart TVs.

    The best Amazon Fire TV devices deliver easy access to popular streaming services. Fire TV products are some of our favorite streaming solutions thanks to their snappy speed and affordable prices. Right now, you can choose between stick, cube, and full-fledged smart TV models.

    Entry-level Fire TV options, like the standard Fire TV Stick, offer full HD playback, while the best Fire TV models, like the second-gen Fire TV Stick 4K Max, support Ultra HD video and Dolby Vision for enhanced color and contrast. Amazon also sells its own smart TVs that have the Fire TV operating system (OS) built in. Though these sets don't rank among the top TVs you can buy, they're decent budget options for fans of Amazon's ecosystem.  

    But with so many different Fire TV models to consider, it can be tricky to determine which is right for your needs. To help you pick the best Fire TV stick or display for your setup, we've detailed all the ins and outs of each model.

    How to get a great deal on the best Fire TV devices

    The best Fire TV sticks and smart TVs often drop to all-time low prices during sales on Black Friday, Cyber Monday, and Amazon Prime Day, though smaller discounts pop up throughout the year outside these big events.

    When on sale during major holidays, you can snag Fire TV Sticks for as much as 50% off. The next big deal event will be Amazon Prime Day, which typically occurs in July. 


    Fire TV Stick Lite

    The Fire TV Stick Lite is the best Fire TV you can snag on a budget. Like the company's other stick models, this compact dongle plugs into your TV's HDMI port. Once powered on, you can navigate through the stick's interface to access all of the best streaming services

    The Fire TV Stick Lite matches the video quality of the more expensive standard Fire TV Stick. The only notable difference between this model and the regular Stick is its remote. The Lite includes an Alexa Voice Remote Lite, which lacks TV controls, like power and volume buttons. Other than that, both models are essentially the same.

    The Fire TV Stick Lite can stream videos at up to 1080p resolution, which makes it ideal for an HDTV. The device also supports high dynamic range (HDR) using the HDR10 and HDR10+ formats. This feature delivers enhanced colors and contrast when streaming HDR videos through apps like Disney Plus. That said, most TVs that support HDR are 4K models, and if you have a 4K TV, we highly recommend you pay a bit more for one of Amazon's 4K sticks.

    If your TV doesn't support 4K, the Fire TV Stick Lite will suit your streaming needs just fine. Keep in mind, however, that the standard Fire TV Stick occasionally goes on sale for even less than the Lite. When that happens, there's no reason to consider this model.


    Fire TV Stick

    The standard Fire TV Stick matches the 1080p streaming quality of the Lite model but has an improved remote with TV controls like power and volume.

    The base Fire TV Stick will meet most people's HD streaming needs, but if you own a 4K TV, we recommend spending the extra money on one of Amazon's more advanced 4K streaming devices.


    Fire TV Stick 4K

    As the name suggests, the Fire TV Stick 4K streams at a higher resolution than the Fire TV Stick or Stick Lite. With 4K support, you'll get a sharper, more detailed image when watching 4K videos on a 4K TV. 

    This model also carries over HDR playback but adds support for the more advanced Dolby Vision format, which is missing on the Lite and standard Fire TV Stick. Dolby Vision can give your TV more detailed guidance for displaying HDR images, but only when watching Dolby Vision content on a compatible display. Check out our HDR TV guide for more details about different HDR formats.

    The latest version of the Fire TV Stick 4K was released in September 2023. It has a slightly tweaked design with rounded edges, more memory, and an improved processor. Amazon says it's around 25% faster than the first-gen model. It also now supports WiFi 6 when used with a compatible router. 

    This model is a good fit if you have a 4K TV. However, if you're willing to spend $10 more, the Fire TV Stick 4K Max offers slightly better performance.

    Fire TV Stick 4K Max

    The Fire TV Stick 4K Max is one of our picks for the best streaming devices you can buy. It carries over everything you get with the regular Fire TV Stick 4K while offering a faster processor and GPU, as well as more storage. This makes navigation a little snappier and lets you save more apps and games.

    Amazon released the latest version of its Fire TV Stick 4K Max in September 2023. Compared to the previous-generation edition, this new model has an upgraded processor, double the amount of storage, and support for WiFi 6E routers. It also has a revised design with rounded edges. Unlike other Fire TV Sticks, the 4K Max supports Amazon's Fire TV Ambient Experience, which lets you display art, photos, and widgets for things like the weather and your calendar. 

    The Fire TV Stick 4K Max is typically just $10 more than the standard Fire TV Stick 4K, so we think it's the best Fire TV option for people with 4K TVs.


    Fire TV Cube

    The Fire TV Cube is the best Fire TV for pure processing power. It incorporates all the features of the Fire TV Stick 4K Max but has a beefier CPU and is meant to be a more traditional home theater device. Instead of a dongle that hangs out of your TV's HDMI port, the Cube is a compact box that sits on your TV stand. 

    One of the Fire TV Cube's biggest benefits is its support for hands-free Alexa voice control without a remote. In other words, the Cube can act like an Echo device. The newest model also has an HDMI passthrough port to control cable boxes, twice as much storage space as the stick models, 4K upscaling to make HD videos look better, and overall faster performance.

    The Fire TV Cube is a premium streaming box designed to compete with devices like the Apple TV 4K and the Roku Ultra, so it's best suited for home theater enthusiasts who want the brand's absolute best quality and fastest technology.


    Fire TV 2-Series

    Amazon also sells its own lineup of full-fledged smart TVs, which all use a built-in version of the Fire TV OS. This means you can stream your favorite apps without an extra device. Though Amazon's displays don't make our guide to the best TVs, they're still worthwhile budget options if you're a fan of the Fire TV ecosystem. The 2-Series is Amazon's entry-level HDTV model designed for people who just want a basic smart TV for casual viewing. 

    The 2-Series is available in a 32-inch 720p screen or 40-inch 1080p screen. Both models support HDR processing using the standard HDR10 format, but the 2-Series can't deliver the brightness or color needed to really take advantage of high-dynamic-range playback. For this reason, we only recommend this model for people who want a cheap TV that doesn't take up too much space.


    Fire TV 4-Series

    The 4-Series steps things up from HD to Ultra HD with a 4K resolution screen. Models are available in 43-, 50-, and 55-inch sizes. 

    Though it supports 4K playback, the 4-Series has subpar HDR performance and lacks advanced features like wide color support and Dolby Vision. It's a decent TV for buyers who want a smaller, affordable 4K display for a bedroom, but it's not suited for home theater use.


    Fire TV Omni Series

    The Omni Series Fire TV adds support for hands-free Alexa voice control without using the remote. You can control power, volume, navigation, and search with spoken commands through the TV's built-in microphones. And the TV can also serve as an Alexa smart home hub even when the display is off. 

    Models range in size from 43 to 75 inches. Every model supports 4K resolution and HDR10, and the 65- and 75-inch models add support for Dolby Vision.

    Unfortunately, the TV's picture quality and navigation speed are underwhelming for its price. There are simply better-looking displays from brands like TCL and Hisense that cost around the same. That said, the Omni is a decent buy when it's on sale during deal events like Black Friday and Prime Day. We only recommend picking up the 65-inch model when you can snag it for under $500. 

    Check out our Amazon Fire TV Omni review.


    Fire TV Omni QLED Series

    Amazon's Omni QLED is the best Fire TV display you can buy, and it offers a big step up from the regular Omni Series. It carries over hands-free Alexa support while adding advanced picture features like quantum dots and local dimming. These features enable it to deliver much better color and contrast performance. 

    The TV also has an ambient mode that can display art and widgets when it senses someone has walked into the room. Sizes range from 43 to 75 inches, but the 43-inch model does not include local dimming.

    The 65-inch model's list price of $800 is high for what you get, and the set doesn't match the overall performance of the very best 4K TVs in this class. However, we've seen it drop to $600 during big sales events, offering much better value at that price. 

    Check out our full Amazon Fire TV Omni QLED review.

    Fire TV Soundbar

    Amazon's latest Fire TV-branded product isn't actually a streaming device at all. Instead, it's a soundbar.

    The Fire TV soundbar is a compact 2.0-channel speaker designed to rest in front of your TV. It features an HDMI eARC and optical port for easy connection to most modern displays, and it also supports Bluetooth for wireless music playback from a mobile device.

    At 24 inches wide, the soundbar is relatively small, which should make it easy to set up on most TV stands. Though it doesn't include a subwoofer or offer advanced features like up-firing audio drivers with Dolby Atmos support, the Fire TV Soundbar does support DTS Virtual:X to simulate surround sound. That said, at this price range and performance class, buyers shouldn't expect too much from this feature.  

    And despite the Fire TV branding, this is a soundbar only. It does not feature built-in support for streaming video apps. The base model only includes a standard remote, but you can pay more for a package with an Alexa Voice Remote Pro

    Based on the specs and affordable $120 price tag, Amazon is positioning this as an entry-level soundbar for people who just want a simple, compact, and inexpensive upgrade for their TV's speakers.

    But if you're looking for something with more oomph, check out our soundbar buying guides to see our top recommendations:

  • 4 Delta credit cards offer an annual companion plane ticket — an incredible value if you know how to use it

    The offers and details on this page may have updated or changed since the time of publication. See our article on Business Insider for current information.

    Affiliate links for the products on this page are from partners that compensate us and terms apply to offers listed (see our advertiser disclosure with our list of partners for more details). However, our opinions are our own. See how we rate credit cards to write unbiased product reviews.

    Delta 757-200 Comfort Plus
    If you have the premium Delta Reserve card, you can use the companion certificate for a Comfort+ seat.

    • Four Delta credit cards offer a companion certificate each year on your account renewal anniversary
    • Delta companion certificates are essentially a buy-one-get-one coupon for domestic flights.
    • When you book yourself a round-trip ticket, bring a companion for just the cost of taxes and fees.

    Delta credit cards come with great perks for Delta flyers, like free checked bags and priority boarding on Delta flights, airport lounge access, and discounts on certain inflight purchases.

    One of the most valuable Delta benefits is the ability to bring a friend or family member with you for just the cost of taxes and fees. This benefit comes in the form of an annual companion certificate — and four co-branded Amex Delta credit cards offer it:

    • Delta SkyMiles® Platinum American Express Card
    • Delta SkyMiles® Platinum Business American Express Card 
    • Delta SkyMiles® Reserve American Express Card
    • Delta SkyMiles® Reserve Business American Express Card

    It's possible to get a lot of value from each of these bonuses — read our post on how to earn and redeem Delta miles for tips.

    You'll earn a companion certificate after your first year of holding one of these cards, then receive another one each year that you renew your card membership. Depending on how you use your companion benefit, you could save hundreds — or even thousands — of dollars each year.

    You can easily offset your credit card's annual fee if you take full advantage of this certificate each year. For example, the Delta SkyMiles® Reserve American Express Card charges a $650 annual fee.

    The amount you save will depend on the amount you spend. If you book a $1,000 seat for yourself, you can bring a friend for just the cost of taxes and fees, saving nearly $1,000. If you and a travel buddy wanted to fly from Atlanta to Seattle in business class, for example you might pay $1,500 per ticket. But with the companion certificate, you could buy one ticket and bring your buddy along for just the cost of taxes and fees — effectively cutting your price per ticket in half.

    This certificate can be particularly beneficial for travelers who are purchasing travel for work on their own dime, then filing for reimbursement later on. 

    Delta credit cards offer different companion certificates

    The companion certificate is essentially a buy-one-get-one coupon. You'll only pay for the taxes and fees of your companion when flying Delta, Delta Connection, and Delta Shuttle flights.

    Depending on which card you have, you can use the certificate for travel in economy, or in any class:

    • Delta SkyMiles® Platinum American Express Card: Companion Certificate valid for domestic, Caribbean, or Central American travel in Main Cabin ($350 annual fee)
    • Delta SkyMiles® Platinum Business American Express Card: Companion Certificate valid for domestic, Caribbean, or Central American travel in Main Cabin ($350 annual fee)
    • Delta SkyMiles® Reserve American Express Card: Companion Certificate valid for domestic, Caribbean, or Central American travel in Main Cabin, Delta Comfort+, or First Class ($650 annual fee)
    • Delta SkyMiles® Reserve Business American Express Card: Companion Certificate valid for domestic, Caribbean, or Central American travel in Main Cabin, Delta Comfort+, or First Class ($650 annual fee)

    As you can see, both Delta Reserve credit cards demand a significantly higher fee because they also offer Delta Sky Club access and Amex Centurion lounge access when you're flying Delta. Reserve card members receive 15 Delta Sky Club visits per year, and can earn unlimited visits each year if they spend $75,000 or more on the card on eligible purchases within the prior calendar year.

    If you're not sure which of these cards is best for you, check out our comparison of the Delta Platinum and Reserve cards to help decide.

    You can't fly just anywhere with a Delta companion certificate

    Delta companion certificates can only be booked via Delta's certificate redemption page, and have limitations on where you go, what fare class you book, and which carriers you can travel with.

    Here's what you should know: 

    Companion certificates are limited to the U.S., Caribbean, Mexico, and Central America

    As of February 2024, Delta companion certificates are valid for round-trip flights to all 50 states, Puerto Rico, the U.S. Virgin Islands, Mexico, Antigua, Aruba, Bermuda, Bonaire, Grand Cayman, Cuba, Jamaica, Bahamas, Turks and Caicos, Dominican Republic, Saint Kitts, St. Maarten, St. Lucia, Costa Rica, Belize, Guatemala, Panama, Honduras, and El Salvador.

    Most companion certificate fares require an advance purchase of up to 14 days, for round-trip travel with a minimum of three days and a maximum of 30 days. 

    Travelers are eligible for upgrades, based on the highest level of elite status held between both travelers.

    Delta companion certificates only work for Delta-operated flights in select fare classes

    Holding a companion certificate doesn't mean you can book any flight within the contiguous U.S. You can only purchase flights on Delta, Delta Connection, and Delta Shuttle flights.

    You must also pay attention to the specific "fare class" of each cabin. Fare classes are letters airlines use to categorize each seat on the plane that determine qualities such as price, ticket flexibility, eligibility for upgrades, and more.

    The following fare classes are eligible for Delta companion certificate travel:

    • Main Cabin (Economy): L, U, T, X, and V fares
    • Comfort+: W and S fares, but only when L, U, T, X, and V fares are available in Main Cabin (Delta Reserve cards only)
    • Delta Premium Select: A and G fares
    • First Class: I and Z fares (Delta Reserve cards only)

    The permitted economy fare classes cover most of the cheaper and mid-priced coach fares, as well as some pricier ones. You shouldn't have much trouble finding eligible flights in economy class as long as you're booking at least one month in advance.

    You must use your eligible Delta credit card to pay for companion certificate travel

    When reserving a companion certificate, you must book with your Delta Platinum or Delta Reserve credit card to activate the benefit. You must also book both seats at the same time. However, you can use Delta eCredits toward companion certificate travel, if you have them. 

    You can't combine any web-special fares or eCoupons with your payment method. Also, you cannot use Delta miles in tandem with a Delta companion certificate. You must purchase your fare with your eligible card to qualify.

    Bottom line

    The Delta companion certificate can be one of the most valuable ongoing credit card benefits in the travel credit card world — but only if you can use it, and know how to do so effectively.

  • 5 things to watch on the ASX 200 on Friday

    Business woman watching stocks and trends while thinking

    On Thursday, the S&P/ASX 200 Index (ASX: XJO) had another good session and stormed higher. The benchmark index rose 0.7% to 7,821.8 points.

    Will the market be able to build on this on Friday and end the week on a high? Here are five things to watch:

    ASX 200 to rise again

    The Australian share market looks set to end the week on a positive note despite a relatively poor session on Wall Street. According to the latest SPI futures, the ASX 200 is expected to open 17 points or 0.2% higher this morning. On Wall Street, the Dow Jones was up 0.2%, but the S&P 500 was flat and the NASDAQ was down 0.1%.

    Oil prices climb

    It looks like ASX 200 energy shares Beach Energy Ltd (ASX: BPT) and Karoon Energy Ltd (ASX: KAR) could have a good finish to the week after oil prices charged higher overnight. According to Bloomberg, the WTI crude oil price is up 2% to US$75.59 a barrel and the Brent crude oil price is up 1.9% to US$79.89 a barrel. Traders were buying oil after the European Central Bank cut interest rates.

    Buy Treasury Wine shares

    The Treasury Wine Estates Ltd (ASX: TWE) share price could be good value according to analysts at Goldman Sachs. In response to its North America and guidance update, the broker has reiterated its buy rating with an improved price target of $13.40. Goldman commented: “We reiterate Buy given positive delivery of the strategy reset as well as attractive double-digit EPS growth at an attractive valuation.”

    Gold price rises again

    ASX 200 gold shares including Evolution Mining Ltd (ASX: EVN) and Northern Star Resources Ltd (ASX: NST) could have a positive finish to the week after the gold price pushed higher overnight. According to CNBC, the spot gold price is up 0.7% to US$2,392.7 an ounce. Rate cut optimism appears to have given the precious metal a boost and lifted it to a two-week high.

    Life360 shares make Wall Street debut

    Life360 Inc (ASX: 360) shares will be in focus today when they return from their trading halt. The location technology company halted its shares yesterday as it completed its Nasdaq IPO. Life360 listed on Wall Street at US$27.00 per new share. However, the company’s debut was relatively subdued, with its shares ending the session exactly where they started it. Management stated that it “views the Offering and increased exposure to U.S. investors as a natural next-step in its growth.”

  • Guess who just slapped a buy rating on BHP shares?

    A little boy holds his fingers to his head posing as a bull.

    BHP Group Ltd (ASX: BHP) shares have just found a new bull.

    And according to the broker, investors should be snapping up the Big Australian’s shares before it’s too late.

    Who is bullish on BHP shares?

    The broker in question is Goldman Sachs.

    According to a note out of the investment bank, its analysts have reinstated coverage on the miner with a buy rating and $49.00 price target.

    Based on the current BHP share price of $44.05, this implies potential upside of 11.2% for investors over the next 12 months.

    But that isn’t the end of the returns. Goldman is forecasting fully franked dividend yields of 4.9% in FY 2024 and then 4.3% in FY 2025.

    This stretches the total potential 12-month return from BHP shares to around 16%.

    Why should you invest?

    Goldman has named a few reasons why it thinks investors should be picking up the mining giant’s shares today. One is its attractive valuation. It said:

    BHP is currently trading at ~6.0x NTM EBITDA (25-yr average EV/EBITDA of 6.6x), a slight premium to RIO on ~5x; both are trading at ~0.9xNAV. Over the last 10 years, BHP has traded at a ~0.5x premium to global mining peers. We believe this premium can be partly maintained due to ongoing superior margins and operating performance (particularly in Pilbara iron ore where BHP maintains superior FCF/t vs. peers).

    The miner’s exposure to copper is another reason to invest according to the broker. It adds:

    We remain bullish on copper and expect BHP to generate US$6.8bn in copper EBITDA in FY24 (27% of EBITDA) and almost doubling to US$11.5bn in FY25 (41% of EBITDA) due to ongoing supply side challenges and increasing demand.

    In addition, Goldman highlights that the company has a significant growth opportunity in copper despite its recent failure to acquire Anglo American (LSE: AAL). It said:

    We continue to believe that BHP’s major opportunity is growing copper production in Chile at Escondida and Spence, and growing production and capturing synergies in South Australia between Olympic Dam and the previous OZL assets. We think BHP has a competitive edge in copper heap leaching and believe it can potentially fill ~200ktpa of spare cathode capacity by 2030 and possibly the full ~315ktpa spare capacity by 2035.

    Overall, this could make BHP shares a great option for investors that are looking for some mining sector exposure for their portfolio this month.

  • The best soundbars: Top 9 picks for upgrading your TV speakers

    When you buy through our links, Business Insider may earn an affiliate commission. Learn more

    Sonos Arc
    The best soundbars include models from brands like Sonos.

    The best soundbars deliver a convenient way to upgrade your home audio setup. Even top TVs often have wimpy built-in speakers that lack depth and clarity. A good soundbar can be a game changer, providing clearer dialogue and deeper bass. 

    To help you find the right audio system for your setup, we've picked the best soundbars you can buy. The Yamaha YAS-209 is our top recommendation for anyone who wants a great all-around audio solution with good sound quality and a subwoofer at an affordable price. But buyers who crave a full-fledged Dolby Atmos system with rear surround sound speakers and up-firing drivers should check out the Samsung HW-Q990C

    Below, you can find all nine of our picks for the best soundbars of 2024. We have options for every price range and type of user, from entry-level two-channel models to high-end systems with 11.1.4 audio channels.

    Our top picks for the best soundbars

    Best overall: Yamaha YAS-209 – See at Amazon

    Best premium Dolby Atmos system: Samsung HW-Q990C – See at Amazon

    Best midrange for Dolby Atmos: Vizio Elevate 5.1.4 Channel Soundbar – See at Amazon

    Best entry-level Atmos bar: Bose Smart Soundbar 600 – See at Amazon

    Best for budget shoppers: Vizio V-Series V21d-J8 – See at Amazon

    Best virtual surround sound: Sennheiser Ambeo Soundbar Max – See at Amazon

    Best all-in-one option: Sonos Arc – See at Amazon

    Best for gaming: Sony HT-A7000 – See at Amazon

    Best with video streaming: Roku Streambar – See at Best Buy


    Best overall

    The YAS-209 delivers the perfect blend of solid audio quality, ease of use, and affordable pricing, making it the best soundbar for most people. This is the type of space-saving audio option many think of when looking for a soundbar, and it makes for a great upgrade to built-in TV speakers.

    The system includes a 36-inch soundbar unit and a wireless subwoofer for dedicated bass. The 2.1-channel hardware delivers stereo playback but also has DTS Virtual:X processing for a simulated surround sound effect. It's not as convincing as the pricier virtual surround systems we recommend, but it does a decent job. With or without virtual surround, the system provides clear and balanced audio for various types of content.

    The YAS-209 connects to your TV using its HDMI ARC port, and the soundbar has a handy HDMI-in port that supports passing through video at up to 4K resolution at 60Hz with HDR (but not Dolby Vision) from a connected device, like a gaming console or Blu-ray player. An optical audio port is also featured for older TVs without HDMI ARC, and you can wirelessly stream music via Bluetooth or WiFi.

    Thanks to built-in microphones, the YAS-209 even includes integrated support for Amazon Alexa, enabling hands-free control for functions like volume. All this at such a low price keeps the YAS-209 at the top of the list for many shoppers and reviewers alike, making it one of the best soundbars you can buy.


    Best premium Dolby Atmos system

    Samsung's flagship 11.1.4 Q990C is one of the best Dolby Atmos soundbars on the market. This has been a progressive process for Samsung over several years, resulting in a massive multi-piece system with 22 speakers working together to utterly submerge you in seamless sound. 

    Dolby Atmos technology is designed to spread audio effects in all directions, including from above your head, and the Q990C is perfectly equipped for the task. Armed with four up-firing drivers to bounce Atmos sound effects off your ceiling, four side-firing drivers, a pair of dedicated rear speakers, a brawny subwoofer, and an array of additional drivers, the HW-Q990C is a powerful machine that drops you directly into the action.

    But this system isn't just about muscle. It also provides excellent balance and fluid transition between speakers, helping it excel at enhancing everything from sitcoms and action flicks to jazz and hip-hop.

    Samsung HW-Q990C soundbar on a TV console shown from the side to showcase the firing drivers.
    Samsung's Q990 is closer to a full-fledged home theater system than a traditional soundbar (Q990C model pictured).

    The system is loaded with features, from built-in Alexa voice control to support for every major audio format. In addition to Dolby Atmos, the Q990C is compatible with the rival DTS:X format and many high-resolution audio files. Inputs include HDMI eARC, an Optical connection, and a pair of HDMI inputs with 4K HDR passthrough (though they stop short of HDMI 2.1 support for 120Hz gaming).

    Accessories include a stylish and intuitive remote, or you can use the Samsung SmartThings app for fine-tuning settings like EQ and individual channel volume. The soundbar is also designed to pair with many of the best Samsung TVs, like the S90C 4K OLED, via Q-symphony, which lets you use your TV's speakers as part of a combined audio system with the Q990C. 

    Buyers should note that Samsung now sells a new 2024 version of this soundbar, the Q990D. The updated model retains the same basic design while adding a few features, including HDMI 2.1 support for 4K/120Hz passthrough when connected to a PS5 or Xbox Series X. For now, we think the cheaper Q990C remains a better value, but the Q990D is a worthy option if you want its added gaming capabilities. 

    Read our Samsung HW-Q990C Soundbar review


    Best midrange for Dolby Atmos

    If you want an Atmos-capable audio system for under $1,000, it's tough to beat the immersive performance of Vizio's Elevate soundbar. It's pricier than standard soundbar packages, but it's one of the most affordable ways to enjoy a full 5.1.4 Dolby Atmos experience.

    The Elevate offers left, center, and right channels in the soundbar itself, along with two upward firing channels that bounce sound off your ceiling to create overhead effects. Two wired rear speakers with their own upward-firing drivers and an eight-inch wireless subwoofer are also included.

    The Elevate has a unique rotating speaker that can beam sound up or forward.

    In an intriguing design twist, the Elevate's front height speakers feature a rotating mechanism that allows them to automatically tilt up or forward depending on what you're listening to. When fed a 3D audio mix like Dolby Atmos or DTS:X, they move up to produce overhead effects. For other mixes, they face forward, helping to create a wider and more powerful front soundstage. 

    The Elevate's relatively large size and wired rear speakers make it more onerous and less space-saving than many soundbar options, but the system provides audio performance that's nearly on par with some traditional home theater packages at a relatively low price.

    Best entry-level Atmos bar

    As its name implies, the Bose Smart Soundbar 600 is designed as a soundbar and smart speaker in one. It has built-in microphones with Amazon Alexa voice control and supports Google Assistant when paired with a separate device. It's also one of the most budget-friendly Dolby Atmos soundbars you can buy. 

    Buyers can use the Bose Music App for easy setup, intuitive controls, and access to popular streaming services like Spotify and Amazon Music. You can stream additional services like Apple Music using AirPlay 2, Chromecast, or Bluetooth. The Bose Smart Soundbar 600 can also be paired with other Bose speakers to create a multi-room audio system or to add satellite speakers for a true surround sound setup.

    The Bose Smart Soundbar 600 is a great Alexa and home theater speaker in one.

    Despite its compact size, the Smart Soundbar 600 delivers impressive audio performance, with surprisingly full and clear sound from such a small profile. We were especially pleased by how clear dialogue sounds, even when watching big action scenes. And unlike other Dolby Atmos soundbars in this price range, like the Sonos Beam, this Bose model has true up-firing drivers to deliver more convincing overhead audio.

    On the downside, the Soundbar 600 doesn't support DTS audio formats and lacks some kick in its lower bass registers. You can pair it with a Bose subwoofer, like the Bose Bass Module 500, but that doubles the price.

    Still, even without a separate subwoofer, the Bose Smart Soundbar 600 is easily one of the best soundbars out there for $500, especially if you want Dolby Atmos, clear dialogue, and Alexa smarts in one compact device.

    Best for budget shoppers

    The Vizio V-Series V21d-J8 is a simple 2.1-channel soundbar built for buyers on a budget. It doesn't offer advanced audio performance or Dolby Atmos support, but this affordable bar still delivers a decent upgrade over the built-in speakers found on most entry-level and midrange TVs. 

    The soundbar has built-in woofers, meaning you'll get two main channels for pure stereo sound and a little extra bass, even though the system doesn't have a separate subwoofer unit. Vizio also uses DTS Virtual:X processing to simulate surround and height effects. The tech employed here is nowhere near as advanced as what you'd get on a high-end soundbar like Sennheiser's Ambeo Max, but it still helps to expand the device's soundstage.

    Standing out from the typical boxy design we see on most soundbars, the V-Series has angled sides that slope down to create a hexagonal profile. Buttons for various controls, including volume, source, Bluetooth audio, and power, rest on the side of the bar.

    The soundbar has an HDMI ARC port for easy connection to modern smart TVs, and you also get an optical audio port if your TV doesn't have an HDMI connection. There's no HDMI video passthrough, but you can hook up older audio sources to the bar's 3.5mm auxiliary port.

    The V-Series supports Bluetooth for wireless playback, making it easy to stream music from your smartphone, but you can't stream via WiFi. An included remote handles all your needs for adjusting volume, accessing basic equalizer options, and toggling various modes.

    Check out our full guide to all of the best budget soundbars.


    Best virtual surround sound

    If you want an absolutely killer listening experience without the hassle of setting up multiple speakers, look no further than the Sennheiser Ambeo Soundbar Max. This high-end soundbar uses premium components and innovative software to create an unparalleled virtual surround sound experience from a single audio component.

    The Ambeo Max is a beast of a soundbar, coming in at 50 inches wide and 40 pounds, making it tricky to fit in some living room setups. But its hefty design enables Sennheiser to pack in five tweeters, six four-inch drivers at the front and sides, and a pair of 3.5-inch up-firing speakers. The up-firing and side-firing drivers bounce audio off your ceiling and walls to make it sound like effects are coming from all around you in a full 5.1.4-channel configuration.

    Sennheiser's Ambeo Max delivers an incredibly immersive experience from a single-unit soundbar.

    The bar creates an immersive soundscape with the most realistic sense of surround sound we've heard from a single soundbar. While not as convincing as having actual rear and overhead speakers, the Ambeo Max is more convenient than having a full-sized system with multiple speakers.

    As you'd expect from Sennheiser, the Ambeo Max is also excellent for music streaming, providing rich and detailed sound across genres. And though the soundbar doesn't include a dedicated subwoofer, mid-bass performance is deep and impactful. You can also add a separate subwoofer from your brand of choice if you crave more low-frequency oomph. 

    Like most of our best soundbar picks, the Ambeo Max supports WiFi and Bluetooth for wireless music streaming directly from many of the best music streaming services, such as Spotify and Apple Music.

    Read our Sennheiser Ambeo Soundbar Max review.


    Best all-in-one option

    In many ways, the Sonos Arc is the quintessential all-in-one soundbar. It offers a slick and stylish design, rich and immersive audio performance, and a simplified setup to get you up and running in minutes. And that's just for starters.

    Because this is a Sonos soundbar, it's as much about what's inside this system as what you see and hear. Sonos' app makes it easy to stream music from various services, tune the sound to your liking, and even connect other Sonos speakers in a multi-room audio setup or as part of a multi-speaker surround system.

    Armed with support for Doby Atmos, the Arc offers both side-firing and up-firing drivers to surround you in the immersive, hemispheric dome for which the format is prized. With Sonos going all in on Dolby Atmos music, you can also stream new Atmos tracks and remixes from your favorite artists from supported services like Apple Music.

    The Sonos Arc is a great option for buyers who want big sound from just one audio component.

    However, there are some downsides to Sonos' minimalist design. Most notably, the Arc has limited input options. There's no spare HDMI connection or optical port. And though DTS 5.1 audio is supported, the Arc does not support DTS' 3D surround sound format, DTS:X.

    The Arc's typical $899 price point can also be tough to swallow, especially since it doesn't come with a separate subwoofer. It still offers relatively punchy bass performance, though, and its lack of extra trappings is part of what makes this concise package so appealing. With excellent sound and many modern features, the Arc is one of the best soundbars we've tested and a strikingly easy way to upgrade your audio setup.

    Best for gaming

    Sony's HT-A7000 is one of the most immersive single-unit soundbars we've tested, second only to Sennheiser's pricier Ambeo Max. With excellent musicality, punchy bass, and up-firing drivers, this monster-sized bar delivers expressive and powerful performance across content, from Dolby Atmos and DTS:X films to jazz and acoustic music.

    But it's the soundbar's hefty suite of gaming and A/V features that really kicks things up a notch. The system supports a laundry list of high-resolution audio formats, including Dolby TrueHD and DTS-HD Master Audio, multiple high-resolution audio types, and Sony's own 360 Reality Audio format for streaming 3D music from supported apps.

    An angled view of a Sony HT-A7000 soundbar under a TV
    Sony's HT-A7000 has HDMI inputs that support advanced gaming features with a PS5.

    On the gaming front, the HT-A7000 is one of the few soundbars that offers HDMI inputs with full HDMI 2.1 bandwidth support, enabling 4K HDR passthrough at up to 120Hz when connected to a PS5 or Xbox Series X/S. The soundbar also supports passing through VRR (Variable Refresh Rate) and ALLM (Auto low latency mode). And PS5 users get support for unique PlayStation features like Auto Tone HDR Mapping and Auto Genre Picture Mode.

    Streaming over WiFi is available from the usual suspects, including Spotify Connect, AirPlay 2, Chromecast, and Bluetooth. Alexa and Google Assistant control are also supported, but only when paired with a separate smart speaker device.

    At a typical street price of $1,000, price is an obvious barrier here, especially since the system doesn't include a separate subwoofer. Still, the HT-A7000 is a powerful performer with impressive gaming chops, especially for PS5 fans. Buyers should also be aware that Sony has a new soundbar for 2024 called the Bar 9. It's more compact and has two more speaker drivers, but it's also more expensive. For now, we recommend the HT-A7000 as the better value.  


    Best with video streaming

    If you're in the market for a soundbar and a new streaming media player, the Roku Streambar could be the convenient all-in-one device you're looking for. Not only is the Streambar smaller than any other soundbar on our list, but it also includes integrated video playback support for all of the best streaming services.

    When it comes to audio performance, the 2.0-channel soundbar features four 1.9-inch full-range drivers for basic two-channel stereo playback. There are no fancy virtualization options for simulated surround sound, and there's no included subwoofer for extra bass, but the Streambar sounds surprisingly solid for a device of its size.

    To be clear, you won't get the range, accuracy, or separation you'd get on a bigger soundbar, but during our evaluation, the Streambar still offered a nice upgrade over most built-in TV speakers. Its compact design makes it an ideal fit for apartments, dorms, and bedrooms.

    The Streambar can play audio and video streaming apps.

    As a media player, the Streambar provides access to Roku's extensive library of channels, including popular services like Disney Plus, Prime Video, and Hulu. It also supports up to 4K playback with high dynamic range using the standard HDR10 format. But while the navigation speed is decent, the Streambar isn't as snappy as the best streaming devices, like the Roku Ultra.

    Roku's handy voice remote is also included, enabling easy content search. Though digital assistant functionality isn't built-in, the bar is compatible with separate Alexa and Google Assistant devices.

    There are other soundbars on the market with built-in video playback, but the Streambar's compact size, affordable price tag, and reliable Roku interface make it our favorite of the bunch.


    How we test soundbars

    Samsung HW-Q990C soundbar underneath a television with "Captain America: Civil War" playing on its screen.
    We watch various movies and TV shows and listen to different music tracks to help elevate every soundbar we test.

    To determine the best soundbars, we test various key factors, including audio quality, format support, connectivity options, smart features, and overall value

    We also evaluate factors like build quality and aesthetics, as well as how easy a soundbar is to set up and use daily. After all, convenience is a big advantage of using a soundbar over more traditional speaker systems. A good soundbar should be easy to use and integrate into your entertainment setup.

    When reviewing soundbars, we evaluate low-, mid-, and high-frequency performance using a mix of test movies and shows across different genres. We also pay attention to how easy it is to hear dialogue using multiple settings, and we test audio at numerous volume levels to ensure the soundbar can get loud without losing quality. We also listen to various music tracks that have been selected to showcase different frequencies to determine if the soundbar sounds tinny or distorted and if it maintains good sonic detail and instrumental definition for various styles like rock, pop, acoustic music, and hip-hop.


    What to look for in a soundbar

    A side-by-side shot ofa Samsung Q990C subwoofer and Q990C satellite speaker.
    High-end soundbar systems, like the Samsung Q990, include separate subwoofers and satellite speakers.

    When shopping for a soundbar, pay close attention to various specs, including size and the number of audio channels supported.

    Entry-level soundbars tend to be smaller and are limited to basic two-channel stereo sound, while more expensive soundbars are larger and support multiple channels for surround sound effects. Some models consist of a single soundbar unit, others include a separate subwoofer, and some even have extra satellite speakers. Bigger, multi-speaker soundbar systems will deliver the best audio performance, but they'll take up more room. 

    All of the best soundbars support basic stereo PCM and Dolby Digital at the very least. But if you want a more immersive experience, you should look for soundbars that support DTS Virtual:X or true spatial audio formats like Dolby Atmos and DTS:X.

    The best soundbars use HDMI ARC or eARC ports to connect to your TV, but it's also nice when models include additional wired options like optical and 3.5mm to connect to older TVs or additional audio components. Extra HDMI ports to pass through video from connected devices like a Blu-ray player or gaming console are also great but shouldn't be expected on entry-level models.

    Bluetooth music streaming is common on many of the best soundbars, but options supporting WiFi music streaming will deliver even better sound quality. If you want a soundbar that can double as a smart speaker, you should find a model with built-in microphones and Alexa or Google Assistant.


    How do I connect a soundbar?

    The Bose Smart Soundbar 600 inputs shown on a wooden console.
    HDMI ARC is the current standard for connecting a soundbar to a TV, but most models include additional options like an optical port.

    Most soundbars we test connect to a TV via HDMI ARC or eARC. This is the most convenient connection type and the only way to source high-quality formats like Dolby Atmos from your TV directly. In most cases, the HDMI ARC connection also allows you to use your TV remote to control a soundbar's volume and power, reducing clutter.

    Even if you're using a TV that's several years old and doesn't offer 4K HDR resolution, there's a good chance it supports HDMI ARC. You can find out by checking your TV's input section and looking for an HDMI port labeled "HDMI ARC" or "HDMI eARC."

    If your TV does not allow for an HDMI ARC or eARC connection, you must use an alternative connection like an optical digital port. This still allows for good sound quality but doesn't support 3D audio formats like Dolby Atmos. In that case, you may also want to consider upgrading your TV. Budget 4K HDR TVs can now be purchased for about $300 or less, and even some of the best TVs hover around $500, depending on size.


    Soundbar FAQs

    A close-up of the format logos features on the Sennheiser Ambeo Max soundbar.
    Dolby Atmos and DTS:X are popular immersive audio formats that can bring 3D audio to a soundbar.

    Are soundbars worth it?

    Generally, even cheap soundbars deliver better audio quality than the speakers you'll find built into most displays, including many of the best 4K TVs. To keep costs down and ensure that the speakers fit within a flat-screen design, TVs usually include small divers and poor placement that can result in thin, muddy sound. The best soundbars can add more dimension, clarity, and bass to your TV-watching experience. 

    Soundbars can also improve the definition of dialogue and other effects for those with hearing issues. That's especially true for soundbars with a dedicated center channel, where most dialogue and other important movie and TV sound effects are directed.

    What size soundbar should I get?

    Size is an important factor to consider when shopping for a new soundbar. Many compact, single-unit soundbars are built with a width of around 25 inches, while some models, like the Roku Streambar, can be as small as 14 inches wide. On the other end of the spectrum, high-end soundbar models can be as big as 50 inches wide.

    Generally speaking, bigger soundbar models deliver better sound quality since they can incorporate more speaker drivers with larger dimensions. But smaller bars are often cheaper, more convenient, and easier to set up.

    If you plan to put your soundbar on an entertainment console with your TV, you should measure that area before purchasing. This way, you can ensure that the soundbar you choose won't be too wide to rest on your TV stand and that its height won't block your display.

    Can soundbars do surround sound?

    The best soundbars can support multiple audio channels. These channels refer to how many directions sound can be sent through the device. Entry-level soundbars often support two channels for basic left and right stereo playback, but many midrange and high-end models can support surround sound with five or more channels, including a center channel for dialogue, as well as rear channels via extra audio drivers, satellite speakers, or virtualization techniques. 

    Channel specifications are listed as a string of up to three numbers separated by decimal points. The first number represents how many standard ear-level channels are included (left, right, center, surrounds). The second number indicates if the device includes a dedicated low-frequency channel or separate subwoofer for extra bass. The final number indicates how many height channels are included for Dolby Atmos support.

    Buyers who just want a simple upgrade from their TV's integrated audio will likely be satisfied with a compact 2.0 or 2.1 soundbar system. But if you're looking for a more complete home theater experience, you'll want to opt for a 5.1 surround sound system or above.

    What is Dolby Atmos?

    Dolby Atmos is an immersive surround sound format that uses object-based audio mixing. In practice, this means that sounds can be more precisely positioned around your room, with effects placed in all directions, including overhead. For instance, when rain falls from the sky or a helicopter flies overhead, you can actually hear the sound coming from above.

    Dolby Atmos soundbars can use one of two methods to create overhead sound effects. The first involves audio processing to create a simulated sense of height from regular ear-level speakers. The second method uses up-firing drivers angled up instead of forward to bounce sound effects off your ceiling. Generally, good upward-firing drivers provide a much more convincing sense of overhead sound than audio processing can produce alone.

    For more specifics, see our What is Dolby Atmos explainer.

    Do I need a subwoofer?

    A subwoofer can be an integral part of your cinematic and musical experience. Due to basic physics, soundbars alone can't offer the power and authority you'd get in dedicated bass frequencies from even a moderately sized subwoofer. If you're looking for earth-rattling thunder, the deep boom of explosions, and hefty bass beats, you'll want to highly consider a soundbar that either includes a subwoofer or, at the very least, allows you to add one later.

    Best overall
    A Yamaha YAS 209 soundbar.
    The Yamaha YAS-209 is an excellent all-around soundbar.

    The YAS-209 has been around for a few years but is still a top performer. Its perfect blend of solid audio quality, ease of use, and affordable pricing make it the best soundbar for most people. This is the type of space-saving audio option that many shoppers think of when looking for a soundbar, and it makes for a great upgrade to built-in TV speakers.

    The system includes a 36-inch soundbar unit and a wireless subwoofer for dedicated bass. The 2.1-channel hardware delivers stereo playback but also has DTS Virtual:X processing for a simulated surround sound effect. It's not as convincing as pricier virtual surround systems, but it does a decent job. With or without virtual surround, the system provides clear and balanced sound for various types of audio content.

    The YAS-209 connects to your TV using its HDMI ARC port, and the soundbar has a handy HDMI-in port that supports 4K HDR video passthrough (but not Dolby Vision) from a connected device, like a gaming console or Blu-ray player. An optical audio port is also featured for older TVs without HDMI ARC, and you can wirelessly stream music via Bluetooth or WiFi.

    The YAS-209 even includes integrated support for Amazon Alexa thanks to built-in microphones, enabling hands-free control for functions like volume. All of this at such a low price is what keeps the YAS-209 at the top of the list for so many shoppers and reviewers alike, making it one of the best soundbars you can buy.

    When it comes to Atmos-capable soundbar systems, few options are as immersive as Vizio's Elevate soundbar. It's pricier than standard soundbar packages, but it's one of the most affordable ways to enjoy a full 5.1.4 Dolby Atmos experience.

    The Elevate offers left, center, and right channels in the soundbar itself, along with two upward firing channels that bounce sound off your ceiling to create overhead effects. Two rear speakers with their own upward-firing drivers and an 8-inch wireless subwoofer are also included.

    Best premium Dolby Atmos system
    Samsung HW-Q990C soundbar on a TV console shown from the side to showcase the firing drivers.
    Samsung's Q990 is closer to a full-fledged home theater system than a traditional soundbar (Q990C model pictured).

    Samsung's flagship 11.1.4 soundbar is one of the best Dolby Atmos soundbars on the market. This has been a progressive process for Samsung over several years, resulting in a massive multi-piece system with 22 speakers working together to utterly submerge you in seamless sound. 

    Armed with four up-firing drivers, four side-firing drivers (including two in the rear surrounds), a brawny subwoofer, and many other speakers, the HW-Q990B is a monstrous machine that drops you directly into the action. But this system isn't just about muscle — it also provides excellent balance and fluid transition between speakers, helping it excel at enhancing everything from sitcoms and action flicks to jazz and hip-hop.

    The system is loaded with features, from built-in Alexa control to support for major audio formats like Dolby Atmos, DTS:X, and high-resolution audio files. Inputs include HDMI eARC, as well as an Optical connection and a pair of HDMI inputs with 4K HDR passthrough (though they stop short of HDMI 2.1 support).

    Accessories include a stylish and intuitive remote, or you can use the Samsung SmartThings app for fine-tuning settings like EQ and individual channel volume. The system is also designed to work with select Samsung TVs, like the S90C 4K OLED, via Q-symphony, using the TV speakers as part of a combined audio system. 

    Buyers should note that Samsung sells a newer version of this soundbar, the Q990C. But while the new version offers a few minor upgrades related to software and bass response, it's otherwise identical to the Q990B. Since the Q990B is typically sold for less than the Q990C, we still recommend the older model while it remains in stock. But our general impressions apply to both versions.

    Best all-in-one option
    A Sonos Arc speaker on a TV stand.
    The Sonos Arc is a great option for buyers who want big sound from just one audio component.

    In many ways, Sonos' Arc is the quintessential all-in-one soundbar. It offers a slick and stylish design, rich and immersive audio performance, and a simplified setup to get you up and running in minutes. And that's just for starters.

    Because this is a Sonos soundbar, it's as much about what's inside this system as what you see and hear. Sonos' S2 app and software make it easy to stream music from various services, tune the sound to your liking, and even connect other Sonos speakers in a multi-room audio setup or as part of a multi-speaker surround system.

    As the first Dolby Atmos bar from Sonos, the Arc offers both side-firing and up-firing drivers to surround you in the immersive, hemispheric dome for which the format is prized. With Sonos going all in on Dolby Atmos Music, you can also stream new Dolby Atmos mixes and remixes from your favorite artists directly to the bar from supported services like Apple Music.

    There are some downsides to Sonos' minimalist design, including a lack of inputs. The Arc does not include a spare HDMI input or even an Optical input without a separate adapter. And though Sonos has added DTS 5.1 audio support, the Arc does not support DTS' competing 3D surround sound format, DTS:X.

    The Arc's typical $899 price point can also be tough to swallow for some, especially since it doesn't come with a separate subwoofer. It still offers relatively punchy bass performance, though, and its lack of extra trappings is part of what makes this concise package so appealing. With excellent sound and tons of modern features, the Arc is one of the best soundbars we've tested and a strikingly easy way to upgrade your audio setup.

    Buyers who do want to expand the Arc's surround sound performance with additional gear, should consider picking up a Sonos Sub for extra bass and two Sonos Era 300 speakers to serve as rear satellites. We listened to a demonstration with this configuration, and its performance blew us away. However, this setup is pricey. Sonos sells all four components packaged together for $2,256.

    Best smart bar
    The Bose Smart Soundbar 600 is shown on a black and brown console.
    The Bose Smart Soundbar 600 is a great Alexa and home theater speaker in one.

    As its name implies, the Bose Smart Soundbar 600 is designed to be a soundbar and smart speaker in one. It has built-in microphones with Amazon Alexa voice control and supports Google Assistant when paired with a separate device.

    The soundbar makes use of the Bose Music App for easy setup, intuitive control, and access to popular streaming services like Spotify and Amazon Music. You can stream additional services like Apple Music using AirPlay 2, Chromecast, or Bluetooth. The Bose Smart Soundbar 600 can also be paired with other Bose speakers to create a multi-room audio system or to add satellite speakers for a true surround sound setup.

    Despite its compact size, the Smart Soundbar 600 delivers impressive audio performance, with surprisingly full and clear sound from such a small profile. We were especially pleased by how well dialogue comes through, even when watching big action scenes. And unlike other smart soundbars in this price range, like the Sonos Beam, this Bose model has true up-firing drivers to deliver more convincing Dolby Atmos overhead audio.

    On the downside, the Soundbar 600 doesn't support DTS audio formats and lacks some kick in its lower bass registers. You can pair it with a Bose subwoofer, like the Bose Bass Module 500, but that doubles the price.

    Still, even without a separate subwoofer, the Bose Smart Soundbar 600 is easily one of the best soundbars you can get for $500, especially if you want Dolby Atmos, clear dialogue, and Alexa smarts all in one compact device.

    Best for budget shoppers
    A group of people watching TV in a furnished living room using the V-Series V21d-J8.
    The V-Series lacks advanced features, but it's still an affordable way to upgrade your TV's sound.

    The Vizio V-Series V21d-J8 is a simple 2.1-channel soundbar built for buyers on a budget. Its audio performance can't match more expensive models, but it still delivers a decent upgrade over the built-in speakers you'll find on most entry-level and midrange TVs. 

    The soundbar has built-in woofers, meaning you'll get two main channels for pure stereo sound and a little extra bass, even though the system doesn't come with a separate subwoofer. Vizio also uses DTS Virtual:X processing to simulate surround and height effects. The tech employed here is nowhere near as advanced as what you'd get on a high-end soundbar like the Ambeo Max, but it can still help expand the device's soundstage.

    Standing out from the typical boxy design we see on most soundbars, the V-Series has angled sides that slope down to create a hexagonal profile. Buttons for various controls, including volume, source, Bluetooth audio, and power, rest on the side of the bar.

    The soundbar has an HDMI ARC port for easy connection to modern smart TVs, and you also get an Optical audio port if your TV doesn't have an HDMI connection. There's no HDMI video passthrough, but you can hook up older audio sources to the bar's 3.5mm auxiliary port.

    The V-Series supports Bluetooth for wireless playback, making it easy to stream music from your smartphone, but you can't stream via WiFi. An included remote handles all your needs for adjusting volume, accessing basic equalizer options, and toggling various modes.

    Sony's HT-A7000 is one of the most immersive single-unit soundbars we've tested, second only to Sennheiser's pricier Ambeo Max. With excellent musicality, punchy bass, and up-firing drivers, this monster-sized bar delivers expressive and powerful performance across content, from Dolby Atmos and DTS:X films to jazz and acoustic music.

    But it's the soundbar's hefty suite of gaming and A/V features that really kicks things up a notch. The system supports a laundry list of high-resolution audio formats, including Dolby TrueHD and DTS-HD Master Audio, multiple high-resolution audio files, and Sony's own 360 Reality Audio format for streaming 3D music from supported apps.

    On the gaming front, the HT-A7000 is one of the few soundbars that offers HDMI inputs with full HDMI 2.1 bandwidth support, including 4K HDR passthrough at up to 120Hz when connected to a PS5 or Xbox Series X/S. Following a recent firmware update, the soundbar event supports passing through VRR (Variable Refresh Rate) and ALLM (Auto low latency mode). For PS5 users, it also supports advanced features like Auto Tone HDR Mapping and Auto Genre Picture Mode.

    Streaming over WiFi is available from the usual suspects, including Spotify Connect, AirPlay 2, Chromecast, and Bluetooth. There's also support for Alexa and Google Assistant, but only with a separate device.

    At up to $1,400, price is an obvious barrier here, especially since the system doesn't include a separate subwoofer. Still, the HT-A7000 is a powerful performer with impressive gaming chops, especially for PS5 fans.

    Best with video streaming

    The Streambar can play audio and video streaming apps.

    If you happen to be in the market for both a soundbar and a new streaming media player, then the Roku Streambar could be the convenient all-in-one device you're looking for. Not only is the Streambar smaller than any other soundbar on our list, but it also includes integrated video playback support for all of the best streaming services.

    When it comes to audio performance, the 2.0-channel soundbar features four 1.9-inch full-range drivers for basic stereo playback. There are no fancy virtualization options for simulated surround sound, and there's no included subwoofer for extra bass, but the Streambar sounds surprisingly solid for a device of its size.

    To be clear, you won't get the range, accuracy, or separation you'd get on a bigger soundbar, but during our evaluation, the Streambar still offered a nice upgrade over most built-in TV speakers. Its compact design also makes it an ideal fit for apartments, dorms, and bedrooms.

    As a media player, the Streambar provides access to Roku's extensive library of channels, including popular services like Disney Plus, Prime Video, and Hulu. You also get support for up to 4K playback with high dynamic range using the standard HDR10 format. But while the navigation speed is decent, the Streambar isn't as snappy as the best streaming devices, like the Roku Ultra.

    Roku's handy voice remote is included as well, enabling you to search for content easily. Though digital assistant functionality isn't built-in, the bar is compatible with separate Alexa and Google Assistant devices.

    There are other soundbars on the market with built-in video playback, but the Streambar's compact size, affordable price tag, and reliable Roku interface make it our favorite of the bunch.

    How we test soundbars

    We watch various movies and TV shows and listen to different music tracks to help elevate every soundbar we test.

    To determine the best soundbars, we test and research various key factors, including audio quality, format support, connectivity options, smart features, and overall value

    We also evaluate factors like build quality and aesthetics, as well as how easy a soundbar is to set up and use on a daily basis. After all, convenience is a big advantage of using a soundbar over more traditional speaker systems. A good soundbar should be easy to use and integrate into your entertainment setup.

    When reviewing soundbars, we evaluate low-, mid-, and high-frequency performance using a mix of test movies and shows across different genres. We also pay attention to how easy it is to hear dialogue using multiple settings, and we test audio at multiple volume levels to ensure the soundbar can get loud without losing quality. We also listen to various music tracks that have been selected to showcase different frequencies to determine if the soundbar sounds tinny or distorted and if it maintains good sonic detail and instrumental definition for various styles like rock, pop, acoustic music, and hip-hop.

    What to look for in a soundbar
    A side-by-side shot ofa Samsung Q990C subwoofer and Q990C satellite speaker.
    High-end soundbar systems, like the Samsung Q990, include separate subwoofers and satellite speakers.

    When shopping for a soundbar, you should pay close attention to various specs, including the soundbar's size and the number of audio channels it supports.

    Entry-level soundbars tend to be smaller, with support for basic 2-channel stereo sound, while more expensive soundbars are larger and support multiple channels for surround sound effects. Some models consist of a single soundbar unit, others include a separate subwoofer, and some even have extra satellite speakers. Bigger, multi-speaker soundbar systems will deliver the best audio performance, but they'll take up much more room. 

    When it comes to format compatibility, all of the best soundbars support basic stereo PCM and Dolby Digital at the very least. But if you want a more immersive experience, you should look for soundbars that support DTS Virtual:X or true immersive audio formats like Dolby Atmos and DTS:X.

    The best soundbars use HDMI ARC or eARC ports to connect to your TV, but it's also nice when models include additional wired options like Optical and 3.5mm to connect to older TVs or additional audio components. Extra HDMI ports to pass through video from connected devices like a Blu-ray player or gaming console are also great to have but shouldn't be expected on entry-level models.

    Bluetooth music streaming is common on many of the best soundbars, but options supporting WiFi music streaming will deliver even better sound quality. If you want a soundbar that can double as a smart speaker, you should find a model with built-in microphones and Alexa or Google Assistant.

    How do I connect a soundbar?
    The Bose Smart Soundbar 600 inputs shown on a wooden console.
    HDMI ARC is the current standard for connecting a soundbar to a TV, but most models include additional options like an optical port.

    The vast majority of soundbars we test connect to your TV via HDMI ARC or eARC. This is not only the most convenient connection type but also the only way to source high-quality formats like Dolby Atmos from your TV directly. In most cases, the HDMI ARC connection also allows you to use your TV remote to control a soundbar's volume and power, reducing clutter.

    Even if you're using a TV that's several years old and doesn't offer 4K HDR resolution, there's a good chance it supports HDMI ARC. You can find out by checking your TV's input section and looking for an HDMI port labeled as "HDMI ARC" or "HDMI eARC."

    If your TV does not allow for an HDMI ARC or eARC connection, you'll need to use an alternative connection like an optical digital port. This still allows for good sound quality but doesn't support 3D audio formats like Dolby Atmos. In that case, you may also want to consider upgrading your TV. A budget 4K HDR TV can now be purchased at a starting price of about $300 or less, and even some of the best TVs hover around $500, depending on size.

    Soundbar FAQs

    Dolby Atmos and DTS:X are popular immersive audio formats that can bring 3D audio to a soundbar.

    Are soundbars better than TV speakers?

    Generally, even cheap soundbars deliver better audio quality than the speakers you'll find built into most TVs. To keep costs down and ensure that the speakers fit within a flat-screen design, TVs usually include small divers and poor placement that can result in thin, muddy sound. The best soundbars can add more dimension, clarity, and bass to your TV-watching experience. 

    Soundbars can also improve the definition of dialogue and other effects for those with hearing issues. That's especially true for soundbars with a dedicated center channel, where most dialogue and other important movie and TV sound effects are directed.

    How many speaker channels should a soundbar have?

    The best soundbars can support multiple audio channels. These channels refer to how many directions sound can be sent through the device. Entry-level soundbars support two channels for basic left and right stereo playback, but high-end models can support five or more channels, including a center channel for dialogue, as well as surround channels via extra audio drivers, satellite speakers, or advanced virtualization techniques. 

    Channel specifications are listed as a string of up to three numbers separated by decimal points. The first number represents how many standard ear-level channels are included (left, right, center, surrounds). The second number indicates if the device includes a dedicated low-frequency channel or separate subwoofer for extra bass. The final number indicates how many height channels are included for Dolby Atmos support.

    Buyers who just want a simple upgrade from their TV's integrated audio will likely be satisfied with a compact 2.0 or 2.1 soundbar system. But if you're looking for a more complete home theater experience, you'll want to opt for a 5.1 system or above.

    What is Dolby Atmos?

    Dolby Atmos is an immersive surround sound format that uses object-based audio mixing. In practice, this means that sounds can be more precisely positioned around your room, with effects placed in all directions, including overhead. For instance, when rain falls from the sky, or a helicopter flies overhead, you can actually hear the sound coming from above.

    Dolby Atmos soundbars can use one of two methods to create overhead sound effects. The first involves using audio processing to create a simulated sense of height from regular ear-level speakers. The second method uses up-firing drivers angled up instead of forward to bounce sound effects off your ceiling. Generally, good upward-firing drivers provide a much more convincing sense of overhead sound than audio processing can produce alone.

    For more specifics, see our What is Dolby Atmos explainer.

    Do I need a subwoofer?

    A subwoofer can be an integral part of your cinematic and musical experience. Due to basic physics, soundbars alone can't offer the power and authority you'd get in dedicated bass frequencies from even a moderately sized subwoofer. If you're looking for earth-rattling thunder, the deep boom of explosions, and hefty bass beats, you'll want to highly consider a soundbar that either includes a subwoofer or, at the very least, allows you to add one later.

  • Guess which ASX All Ords stock has rocketed 37% in a year AND pays an 11% dividend yield!

    A coal miner smiling and holding a coal rock, symbolising a rising share price.

    The All Ordinaries Index (ASX: XAO) is up 10.31% since this time last year, with one ASX All Ords stock doing plenty of the heavy lifting.

    12 months ago, you could have picked up shares in this company for $4.62 apiece. At market close yesterday, those same shares were trading for $6.31, up a whopping 36.58% in a year.

    But let’s not forget those dividends.

    Over the course of the year the ASX All Ords stock pleased passive income investors by dolling out 69.5 cents a share in fully franked dividends.

    Adding that to yesterday’s closing price, the accumulated value of the company’s shares is up 51.6% in 12 months, with some potential tax benefits from those franking credits.

    Any guesses?

    If you said Yancoal Australia Ltd (ASX: YAL), go to the head of the virtual class.

    Here’s what’s been going right for investors in the ASX All Ords coal stock.

    How has this ASX All Ords stock been smashing the benchmark?

    Yancoal shares first popped onto most investors’ radars in 2022.

    That came as thermal coal prices surged to all-time highs following Russia’s invasion of Ukraine. And it saw the ASX All Ords stock surge 133.1% in 2022.

    Since then, coal prices have returned to earth. But that hasn’t stopped Yancoal from booking impressive profits and building up a serious cash pile.

    Despite focusing on its mine recovery plans in 2023, Yancoal increased its output each quarter. And Q4 2023 marked the highest rate of production for the miner in three years.

    Over the full year the ASX All Ords stock reported $7.8 billion in revenue and $3.5 billion of operating earnings before interest, taxes, depreciation and amortisation (EBITDA).

    That saw the company book an enviable $1.8 billion after-tax profit, which helps explain the market-beating 11.01% dividend yield.

    As for 2024, the first quarter of the year saw Yancoal boost its cash holdings by $260 million. That saw the ASX coal miner holding $1.66 billion in cash as at 31 March.

    Since that time Yancoal will have dipped into its cash holdings to pay out the $429 million final dividend. Eligible shareholders will have seen their portion of that passive income hit their bank accounts on 30 April.

    And the second half of the year is looking promising for the ASX All Ords stock.

    Commenting on that outlook back in April, Yancoal CEO David Moult said, “Yancoal continues to generate robust cash inflows. The AU$180 per tonne price realised [in Q1] was roughly double the cash operating cost we are targeting this year.”

    The post Guess which ASX All Ords stock has rocketed 37% in a year AND pays an 11% dividend yield! appeared first on The Motley Fool Australia.

  • Ukraine isn’t ‘one system away from some massive breakthrough,’ but there are things it can’t get enough of, White House official says

    Ukraine front line
    Ukrainian servicemen of Azov brigade are seen at an artillery position as Russia-Ukraine war continues in the direction of Lyman, Ukraine on April 07, 2024.

    • A White House official says Ukraine needs a consistent flow of capabilities, not one decisive weapon, to defeat Russia.
    • Russia is believed to be producing artillery shells three times faster than Ukraine's NATO partners.
    • The US is co-producing with Kyiv to boost defense industry and compete with Russia.

    Deputy National Security Advisor Jonathan Finer said there isn't a specific single weapon Ukraine needs to defeat Russia. Instead, Ukraine needs a consistent flow of certain capabilities.

    There is this idea out there that "they are one system away from some massive breakthrough where they will get the system and run roughshod over the Russian army," Finer said during a Center for New American Security conference Thursday. "This is not that kind of war," he added.

    Finer said that he wishes the US could provide Ukraine with an endless supply of artillery and air defense weaponry, which Ukraine needs most. "If there are two things that we could provide an infinite number of to the Ukrainians to try and turn the tide of this war, it would be artillery munitions and air defense interceptors," he explained.

    "We just don't make enough of them," he said, adding that "we're making more, and by early next year, we think we'll be in a much stronger position."

    In May, the consulting firm Bain & Company found that Russia is producing artillery shells three times faster than Ukraine's NATO partners for less, and it is expected to refurbish or produce as many as 4.5 million artillery shells this year.

    That said, the US, like some of its allies and partners in Europe, has been working to dramatically increase artillery shell production, particularly the highly sought-after 155 mm shells. Before the Russian invasion of Ukraine, the US was making about 14,000 a month, but the goal is to bring that number up to 100,000 by 2025.

    A serviceman of the 66th separate cannon artillery battalion of the 406th separate artillery brigade of the Armed Forces of Ukraine is pictured by the American M777 howitzer.

    In addition to making more shells, Finer added that the US is launching co-production with Kyiv to boost its defense industry and compete with Russia's manufacturing capabilities.

    Ukrainian soldiers expressed the dire need for artillery and air defense on the battlefield in an interview with CNN last week, with some saying that US-supplied M1 Abrams tanks have not been enough. US veterans who have fought in Ukraine have also said the same thing in the past, especially as Ukraine grappled with debilitating ammo shortages.

    "This conflict between two very similar armies, in some ways, is much more about the basic blocking and tackling that, frankly, I think many of us did not fully appreciate would remain a key facet of modern warfare: production of not super high-tech but critically important munitions, which we have let lapse," Finer said.

    "We are now taking significant action to get our act together on those things," he said.

  • AOC says she ‘wouldn’t be surprised’ if Trump ‘threw me in jail’ if he wins in 2024

    Rep. Alexandria Ocasio-Cortez and former President Donald Trump.

    • AOC suggested that Trump could jail her if he wins the presidency again.
    • "It sounds nuts, but like, I wouldn't be surprised if this guy threw me in jail," she said.
    • "If Donald Trump wins, we are looking at the potential dissolution of democracy," she added.

    Rep. Alexandria Ocasio-Cortez suggested this week that she could be jailed if former President Donald Trump defeats President Joe Biden in November.

    "I mean, it sounds nuts, but like, I wouldn't be surprised if this guy threw me in jail," the New York congresswoman said during an appearance on the "On With Kara Swisher" podcast. "He's out of his mind. I mean, he did his whole first campaign around 'lock her up.' This is his motto."

    Ocasio-Cortez made the remarks after she was asked what Trump's election would mean for not just the country, but the New York congresswoman's future as a politician.

    "It is unequivocal that if Donald Trump wins, we are looking at the potential dissolution of democracy in the United States of America," said Ocasio-Cortez. "The question about what would happen to me or the Democratic Party is a joke compared to the question of what is going to happen to our country."

    Ocasio-Cortez argued that a second Trump term would be far more radical than the first.

    "I feel like what we saw in his first presidency was an amuse-bouche to what his intentions are," said Ocasio-Cortez. "He has learned from his mistakes of appointing professionals, and he will not make that mistake next time."

    The congresswoman also discussed Big Tech, the progressive movement, and why she believes the lack of a cease-fire in Gaza is making it difficult for Democrats to effectively communicate with younger voters ahead of the 2024 election.

    "Nobody right now in a millennial space wants to talk about, or advocate, or engage their bullhorn in a way that they feel is undermining or seeking to distract or undercut attention on the atrocity that Palestinians are facing," said Ocasio-Cortez. "So if you are a Democrat that wants to build support among young people, and shore up your support on economic issues, on your message, on health care, on your message, on wages, on jobs, we need a cease-fire."

    Swisher also asked the congresswoman about her recent spat with Rep. Marjorie Taylor Greene in a House Oversight Committee hearing, where the Georgia Republican insulted Democratic Rep. Jasmine Crockett's "fake eyelashes."

    "Marjorie Taylor Greene's selfishness and narcissism is part of what is screwing over the Republican Party," said Ocasio-Cortez. "While it may be good for her, in a way, she is such an embodiment of their core values that they are trying to distract the public from."

  • A mysterious Jupiter-sized planet that shouldn’t exist is as puffy as a marshmallow and astronomers finally think they know why

    Artist's cocept of exoplanet WASP 107b imaged by
    This artist's illustration shows what exoplanet WASP 107b could look like based on new data from JWST. This warm gas giant confounded researchers until recently.

    • Exoplanet WASP 107b is a gas giant that's nearly as big as Jupiter, but far less massive.
    • Based on this discrepancy, astronomers didn't know how a planet like WASP 107b could exist.
    • But now, two independent teams of researchers have harnessed the power of JWST to solve the mystery.

    Right in our cosmic neighborhood, about 210 light years away, is a planet beyond our solar system that defied scientific explanation for years. Its name is WASP 107b.

    Now, two different teams of astronomers think they've found the solution, but it's launched a series of new questions that will require further research.

    WASP 107b: The exoplanet that shouldn't exist

    Artist's impression of a planet passing in front of its host star with a coronal mass ejection.
    An artist's impression of WASP 107b passing in front of its host star. This planet is almost the same size as Jupiter, but only has 12% of its mass.

    Astronomers first detected this unusual exoplanet in 2017.

    Their initial observations suggested WASP 107b was about as wide as Jupiter in size, but is 10 times less massive, earning it the nickname "super-puff," like a puffy marshmallow or fluffy cotton candy.

    For years, experts struggled to understand how such a planet could grow so big in diameter but remain so light in mass. As far as scientific models were concerned, the exoplanet shouldn't exist.

    "People started to bend over backwards to try to figure out how to make such a planet," David Sing, a Bloomberg distinguished professor at Johns Hopkins University, told Business Insider.

    Typically, planets grow wider just like humans. The more matter they consume, the wider — and more massive — they get. Therefore, if this exoplanet was as big as astronomers observed, then it shouldn't have been so low in mass.

    Artists rendition of a gas giant forming
    Gas giants form when clouds of gas gather around a dense, rocky core. But models suggested that WASP 107b's core would be too small to have formed a gas giant.

    "WASP 107b is an outlier among the outliers," said Luis Welbanks, a NASA Sagan postdoctoral fellow at Arizona State University.

    Now, thanks to the James Webb Space Telescope, two separate research teams — one led by Sing and another by Welbanks — think they've finally cracked the case. What's more, both teams came to remarkably similar conclusions, bolstering each other's findings.

    Both teams posit the answer to this mystery was hiding in WASP 107b's core. It turns out that the center of this exoplanet is much hotter and more massive than astronomers previously thought.

    But to reach that conclusion, the two teams had to do some serious space sleuthing.

    Scientific models didn't align with observations

    nasa hubble telescope space
    Hubble images of WASP 107b didn't solve the mystery of its large size and low density. Astronomers needed a more powerful instrument: JWST.

    Why it took astronomers years to understand WASP 107b's mysterious origins stems from what many astronomers face: a lack of information due to technological limits.

    Thanks to preliminary observations with the Hubble Space Telescope, astronomers knew some information about WASP 107b when it was discovered but not enough to answer the big question.

    So, they initially turned to scientific models to fill in the gaps. One major gap was the exoplanet's core.

    Scientific models suggested the core had to be relatively small and cold, Sing said.

    "Which was a real mystery," he said, since gas giants, like Jupiter and WASP 107b, typically need massive cores to accumulate all that gas. These cores also tend to be hot because otherwise, a cold core would naturally drive it to contract, shrinking its size.

    jwst
    JWST enabled astronomers to take another look at WASP 107b, this time measuring the gasses in its atmosphere to estimate its interior temperature.

    But, according to scientific models, WASP 107b's core was smaller than it should be — measuring no bigger than 4.6 Earth-masses, Sing said.

    So, clearly astronomers weren't seeing the full picture.

    Enter JWST: the most powerful telescope ever launched into space. With this tool, Sing and Welbanks discovered that previous assumptions about WASP 107b's interior were all wrong.

    Probing beneath the surface

    Transmission spectrum for WASP 107-b
    This chart shows the different gasses that make up WASP 107b's atmosphere. When Sing and Welbanks measured methane, the found that there was less than they expected. That was the key to understanding its core.

    To solve the mystery of WASP 107b, Welbanks's and Sing's teams analyzed the exoplanet's atmospheric composition with JWST.

    Each team identified some of the usual suspects like carbon dioxide, sulfur dioxide, and water vapor. But they were surprised to find an unusually low amount of methane.

    Methane is unstable at high temperatures. But WASP 107b's surface temperature was cold enough that it should have had more methane than what JWST observed.

    The most plausible answer to this methane mystery was that hot gas from deeper within the exoplanet was vigorously mixing with the colder gas near the surface, Welbanks and Sing concluded.

    "With these new measurements, we're actually able to use methane as basically a thermometer into the interior, and we find it's much hotter than we expect," Sing said.

    The two teams both published their separate studies in the peer-reviewed journal Nature.

    illustration of james webb space telescope with gold panels against a starry purple background
    JWST may not be able to peer directly into a planet's interior, but it can gather information about its atmosphere to reveal what lies within.

    The fact that JWST's observations suggested the core was hotter also meant it was likely much larger, which would explain WASP 107b's big diameter. Indeed, both Sing and Welbanks concluded that the core is much more massive than the original estimates.

    However, Welbanks and Sing's measurements of the core mass differ. While this discrepancy warrants further investigation, both studies are basically telling the same story, said Scott Gaudi, professor of astronomy at Ohio State University.

    "The fact that this thing is puffy is largely due to a high internal temperature," said Gaudi, who wasn't involved with the research but is a former colleague with a co-author on Welbanks's paper.

    Collaboration is key

    A collage of super puffball exoplanets compared to planets in our solar system
    The results of Sing and Welbanks' collaborative research could inform future studies of other super puffs, like the Kepler 51 planets.

    This clarified picture of WASP 107b's interior doesn't mean astronomers are done asking questions about this strange super puff. One remaining question is how this exoplanet's core got to be so hot, in the first place.

    "Exactly what's causing that high internal temperature is not clear," Gaudi said. But Welbanks and Sing have a theory — one that Gaudi thinks could be right.

    WASP 107b's orbit around its host star is "eccentric," meaning it isn't perfectly circular. That eccentric orbit intermittently squeezes the planet, and "just like playing with silly putty in your hands and moving it around, it gets warm," Welbanks explained.

    That heat-generating squeezing is called tidal heating. Gaudi thinks it's a solid explanation for why WASP 107b's core is so much hotter than expected.

    But Gaudi still has some questions about the mechanisms behind this tidal heating.

    For instance, in order for WASP 107b's eccentric orbit to heat its core this much, the core would have to dissipate tidal heating very efficiently, Gaudi said.

    Map of all known exoplanets
    A NASA map of all 4,003 known exoplanets discovered as of 2019. Each of these planets has its own unique characteristics, and scientists like Sing and Welbanks are helping us understand them.

    That means that each time the exoplanet gets "squeezed" while circling its star, a lot of energy gets deposited into the core. According to Gaudi, that also means that the exoplanet's orbit shouldn't stay eccentric for very long — eventually, it should become perfectly circular.

    So, why is WASP 107b's orbit still eccentric? Have Sing and Welbanks simply caught it at the right time, or is there something else sustaining the exoplanet's wonky orbit, like the pull of a neighboring planet?

    Welbanks and Sing plan to explore WASP 107b's eccentric orbit, tidal heating, and other remaining questions in the future.

    But for Sing, Welbanks, and Gaudi, the most important lesson to be learned from this work is that collaboration yields success.

    "In the era of science where a lot of things are not reproducible, having two teams come up with the same thing right away was very reassuring," Sing said.

    "Science is done in a greater, better fashion when you work together," Welbanks said.
