Finding the best soundbars for 4K TVs is one of those upgrades you do not realize you need until you experience it firsthand. I spent over three months testing 10 different soundbars with various 4K television setups, running movies, sports, games, and music through each one to see which actually deliver on their promises. The difference between your TV’s built-in speakers and even a mid-range soundbar is night and day.
Modern 4K TVs are thinner than ever, and while the picture quality keeps getting better, the audio has actually gotten worse. There is simply no room for decent speakers inside a panel that measures less than an inch thick. That is where a good soundbar comes in, filling the gap between stunning visuals and underwhelming sound.
In this guide, I break down the 10 best soundbars for 4K TVs in 2026, covering everything from budget-friendly options under $100 to premium Dolby Atmos systems that can transform your living room into a mini theater. Whether you watch Netflix every night, game on your PS5, or just want clearer dialogue during the evening news, there is a soundbar here for you.

2-in-1 Soundbar with 4K Streaming
Bluetooth
Optical and HDMI
Weighs 2 lbs
9.6in L x 3.5in W x 2.4in H
I set up the Roku Streambar SE in my guest bedroom where space is tight and the TV sits on a small dresser. What surprised me right away is how this tiny bar, barely 10 inches wide, manages to produce sound that genuinely fills a 12-by-14 foot room. The built-in 4K streaming is the real selling point here. You get a soundbar and a streaming device in one box, which is perfect if your 4K TV does not have smart features or you just prefer the Roku interface.
The setup took me about four minutes. Plug in the HDMI cable, connect to Wi-Fi, and the Roku guided setup walks you through everything. Speech clarity is where this little bar punches above its weight. Dialogue in movies and news broadcasts comes through crisp and centered, even during scenes with heavy background music or action. My wife noticed the difference immediately during her nightly shows.
On the technical side, the Streambar SE uses premium speakers with a dedicated bass port that helps low frequencies more than I expected for a bar this size. The auto volume leveler is a nice touch for late-night watching when commercials suddenly blast at twice the volume of your show. Bluetooth streaming works smoothly for playing music from your phone, and the whole unit weighs just 2 pounds, so wall mounting is effortless.
The downside is bass. Without the optional Roku Wireless Bass subwoofer (sold separately), you will not feel those deep rumbles during action scenes. The remote also feels a bit cheap with basic buttons and no backlighting. And because it is so compact, the stereo separation is limited compared to wider bars. But for the price, the trade-offs are easy to accept.
This is ideal for anyone with a smaller 4K TV setup, a bedroom, dorm room, or kitchen where you want better sound and streaming in one simple device. If you already use and love Roku, the seamless integration makes this a no-brainer. It is also a great gift for parents or grandparents who want a simple audio upgrade without complicated technology.
If you have a dedicated home theater room or want chest-thumping bass for movies, this bar will leave you wanting more. Audiophiles and those with larger living rooms above 250 square feet should look at the TCL S55H or Samsung HW-B400F instead for fuller, more immersive sound.
2.1ch with Wireless Subwoofer
Bluetooth 5.0
HDMI and Optical
40W Output
25.23in Wide
I connected the Samsung HW-B400F to my Samsung 4K TV in the living room and the whole process took about five minutes. The wireless subwoofer paired automatically the moment I plugged both units in, which is the kind of plug-and-play experience I appreciate. The first thing I noticed was how much bass this system produces for the price. Watching the opening scene of Blade Runner 2049, the deep rumble of the bass hit my chest from across the room.
The 2.1 channel setup means you get stereo sound from the bar and dedicated low frequencies from the sub. Smart Sound Lite technology automatically adjusts the EQ based on what you are watching, and it works reasonably well for switching between dialogue-heavy news and bass-heavy action movies. Game Mode is particularly good, adding directional sound cues that helped me pinpoint enemy positions in Call of Duty.
From a technical perspective, the HW-B400F uses Bluetooth 5.0 for a stable wireless connection to the subwoofer and for streaming from your phone. The bar measures just over 25 inches wide, so it fits neatly under most 50 to 65 inch TVs. Samsung’s One Remote feature means if you have a Samsung TV, you can control the soundbar volume and power with the same remote you already use for the TV, cutting down on remote clutter.
The main gripe I have is the remote itself. It uses basic toggle switches instead of proper buttons, which feels cheap for a Samsung product. A few users on Reddit also mentioned occasional audio cutouts when using the optical connection, though I did not experience this over HDMI. And the fact that it is not Prime eligible means slightly longer shipping for some buyers.
This is one of the best soundbars for 4K TVs if you want a wireless subwoofer without spending much. Samsung TV owners get the best experience thanks to One Remote integration. Gamers on a budget will appreciate the directional audio in Game Mode. It is perfect for living rooms up to about 300 square feet.
If you want Dolby Atmos or surround sound, this 2.1 system does not support those formats. Those with non-Samsung TVs lose the One Remote benefit, though the soundbar still works fine with any brand via HDMI ARC or optical. Audiophiles looking for nuanced music reproduction should consider the Polk Audio Signa S2 or Sonos Beam instead.
2.1ch Dolby Atmos and DTS:X
220W Output
Wireless Subwoofer
AI Room Calibration
31.89in Wide
Getting Dolby Atmos and DTS:X support at this price point is rare, and that is exactly why the TCL S55H caught my attention. I tested it with a TCL 4K TV first, then moved it to a Sony Bravia to see how cross-brand compatibility held up. On both TVs, the Atmos effect was noticeable. Sounds moved around the room with a sense of height and width that you simply do not get from standard stereo bars.
The AI Sonic Auto Room Calibration via the TCL app was surprisingly effective. I ran the calibration in my oddly shaped living room with a vaulted ceiling, and the system adjusted the output to compensate for the acoustic oddities. Dialogue was clearer and the bass tightened up after calibration. The 220W power rating means this bar can genuinely fill a medium to large room without straining.
Connectivity is solid with HDMI eARC, ARC, optical, Bluetooth, and AUX inputs. The wireless subwoofer with its 5.5-inch driver adds satisfying bass for movie explosions and music beats. At 31.89 inches wide, the bar sits comfortably under most 55-inch and larger 4K TVs. The wall-mount kit is included, which is a nice touch at this price.
The main drawback is availability. TCL lists shipping at one to four weeks, which tests your patience if you want an immediate upgrade. The subwoofer also could dig a little deeper for true home theater bass, and the TCL app setup process was described as “wonky” by several Amazon reviewers. I had to retry the calibration once before it completed successfully.
Anyone wanting Dolby Atmos on a tight budget should look here first. It is an exceptional value for 4K TV owners who want immersive spatial audio, room calibration, and solid power output without spending over $150. TCL TV owners get extra synergy, but the bar works great with any brand.
If you need a soundbar right now, the shipping delay is a real issue. Hardcore bass enthusiasts who want room-shaking low end should consider the Samsung HW-B400F or invest in the LG S40TR with its rear speakers. Those heavily invested in the Sonos ecosystem should look at the Beam Gen 2 instead.
3.1ch Dolby Atmos and DTS:X
Built-in Subwoofer
HDMI eARC
37in Length
Fire TV Ready
The Amazon Fire TV Soundbar Plus arrived at my door and I had it running within five minutes of opening the box. That kind of simplicity is rare in audio gear. I plugged the HDMI eARC cable into my Fire TV-equipped 4K set, and the soundbar was instantly recognized. No app downloads, no firmware updates, no pairing dance. Just plug in and play.
What impressed me most is the dialogue clarity. Amazon clearly designed this bar with TV watchers in mind. The center channel with its dedicated tweeter makes voices pop through even the most chaotic action sequences. My father-in-law, who constantly struggles to hear dialogue in movies, immediately commented on how much clearer everything sounded during a rewatch of The Dark Knight.
The built-in subwoofer uses two woofers to produce bass that genuinely surprised me. It is not going to rattle your windows, but for a room up to about 250 square feet, the low end is satisfying for movies and music alike. The 3.1 configuration with three full-range speakers, three tweeters, and two woofers gives a wide soundstage that feels bigger than the bar looks. Movie, Music, Sports, and Night modes let you dial in the right EQ for your content.
The limitations show in larger spaces. In my open-concept living room that connects to the kitchen, the soundbar struggled to fill the entire area with authority. A few users also reported that the included HDMI cable did not properly support ARC on their specific TV model, requiring a cable swap. And because the subwoofer is built-in, you cannot upgrade to a more powerful external unit later.
Fire TV owners looking for a hassle-free audio upgrade will love this bar. It is perfect for apartments, bedrooms, and medium-sized living rooms where simplicity matters more than raw power. If you watch a lot of dialogue-heavy content like TV dramas and news, the dedicated center channel is a major advantage.
Large room owners and home theater enthusiasts will want more power and a separate subwoofer. If you do not use Fire TV, many of the integration benefits are lost and you might prefer the Bose TV Speaker or TCL S55H for similar money. Those wanting rear surround speakers should look at the LG S40TR.
4.1ch with Rear Speakers
Wireless Subwoofer
Dolby Audio and DTS
WOW Orchestra
28.4in Wide
Getting true surround sound with rear speakers at this price is almost unheard of, and that is what drew me to the LG S40TR. I set it up in my den with a 55-inch LG OLED, and the moment I fired up a Dolby Atmos movie, the rear speakers made an immediate difference. Helicopter flyovers in action films actually sounded like they were moving from front to back across the room.
The wireless subwoofer paired on its own during first boot, which took one potential headache out of the equation. AI Sound Pro does a good job of leveling out volume between scenes, preventing those jarring jumps between quiet dialogue and explosive action. The WOW Interface feature means my LG TV remote controls the soundbar natively, which is a small but meaningful quality-of-life improvement.
Technically, the S40TR delivers 4.1 channels of audio with Dolby Audio and DTS Digital compatibility. The Clear Voice Plus feature enhances dialogue frequencies without muddying up the rest of the sound. The Smart Up-Mixer takes stereo content and spreads it across all four channels and the subwoofer, giving even regular TV broadcasts a more spacious feel. The LG Soundbar App offers EQ customization for those who want to fine-tune.
There are a couple of quirks to be aware of. The rear surround speakers need to be wired to each other with the included speaker wire, even though the subwoofer is wireless. This means you still need to run a cable along or under your baseboard. A small number of users also reported the subwoofer occasionally disconnecting and reconnecting, though this was rare in my testing.
LG TV owners looking for true surround sound without spending a fortune should start here. The WOW Orchestra feature syncs your TV speakers with the soundbar for an even bigger soundstage. Anyone wanting the immersion of rear speakers for movies and gaming will find this one of the best soundbars for 4K TVs under $250. It is also great for families thanks to the AI Sound Pro volume leveling.
If you do not have an LG TV, you miss out on WOW Orchestra and WOW Interface, which are key differentiators. Those wanting Dolby Atmos object-based audio should look at the TCL S55H or Samsung S60D instead. And if running speaker wire for the rear channels is a dealbreaker, consider a simpler all-in-one bar like the Bose TV Speaker.
2.0 Stereo
2 Angled Full-Range Drivers
HDMI ARC and Optical
23.38in Wide
Weighs 7.6 lbs
Bose has a reputation for sound quality that punches above spec sheets, and the Bose TV Speaker lives up to that. I placed it under a 43-inch 4K TV in my home office, and its low-profile 2.21-inch height meant it did not block the bottom of the screen at all. The two angled full-range drivers create a surprisingly wide soundstage for such a compact unit.
Dialogue mode is the star feature here. Pressing the dialogue button on the remote immediately boosts vocal frequencies, making news broadcasts, podcasts, and movie conversations crisp and easy to follow. I tested this during a rewatch of Westworld, where the whispery dialogue had always been a challenge with my TV speakers alone. The Bose handled it effortlessly.
The connectivity options cover the basics with HDMI ARC, optical, AUX, and Bluetooth. Setup is about as simple as it gets: plug in the optical cable (included in the box), connect power, and you are done. The bass boost button adds some low-end warmth when you want it for music or action scenes. At 7.6 pounds, the unit feels solid and well-built with a premium matte finish.
The downsides are worth noting though. Bose only includes an optical cable, not HDMI, which feels stingy at this price. Bluetooth version 4.2 is two generations behind current standards, meaning shorter range and lower audio quality for wireless streaming. And if you ever want to add a subwoofer, you are locked into Bose’s ecosystem, where the cheapest option costs more than most complete soundbar systems.
Anyone who values simplicity, brand reliability, and clear dialogue above all else will love this bar. It is perfect for smaller rooms, offices, and bedrooms where you want better TV sound without a complicated setup. With nearly 14,000 reviews on Amazon, the consensus is clear that this is a trusted, consistent performer.
Those wanting Dolby Atmos, surround sound, or heavy bass should look elsewhere. The price-to-feature ratio is not the best when you consider the TCL S55H offers Atmos and a subwoofer for less. And anyone wanting to build a surround system over time will find the Bose ecosystem expensive and limiting compared to Sonos or Samsung.
5.1ch with Wireless Subwoofer
VoiceAdjust Technology
Ultra-Slim 2in Design
Dolby Digital
35.43in Wide
With over 21,000 reviews on Amazon, the Polk Audio Signa S2 is one of the most popular soundbars on the market, and after testing it, I understand why. I set it up in my living room beneath a 65-inch 4K TV, and the ultra-slim 2-inch height meant it disappeared visually while the sound filled the room. Polk’s VoiceAdjust technology is not marketing hype; it genuinely works.
I watched three nights of mixed content, from dialogue-heavy dramas to action blockbusters, and the VoiceAdjust made a measurable difference in every scenario. Vocals came through centered and clear, even during the loudest action sequences. The wireless subwoofer provides satisfying bass that rounds out movie soundtracks nicely. Movie, Night, and Music modes let you switch EQ profiles quickly depending on what you are watching.
Technically, the Signa S2 uses five full-range drivers and a 5.25-inch wireless subwoofer to deliver its sound. The bar supports Dolby Digital decoding and connects via HDMI ARC or optical. Bluetooth streaming lets you play music from your phone. The bar works with your TV remote through CEC, so you do not need to add yet another controller to your coffee table. At 35.43 inches wide, it is the widest bar in this lineup and pairs well with TVs 55 inches and up.
The most common complaint from other users, which I also experienced, is wireless interference with the subwoofer. If you have a lot of Wi-Fi devices or your router is near the soundbar, the sub can cut in and out occasionally. Moving the subwoofer closer to the bar resolved this for me. Also, there is no numerical EQ display, just LED indicators, so dialing in your preferred sound takes some trial and error.
Anyone who struggles to hear dialogue in movies and shows should put this at the top of their list. The VoiceAdjust technology is genuinely effective and the ultra-slim design works with virtually any TV setup. With its massive review base, this is one of the safest picks among the best soundbars for 4K TVs. It is a particularly good match for larger TVs where a wider bar fills the space beneath the screen proportionally.
If you want Dolby Atmos or DTS:X, this bar only supports Dolby Digital decoding. Those with crowded wireless environments might find the subwoofer connectivity frustrating. Audiophiles focused on music quality may find the treble slightly harsh at higher volumes compared to the Sonos Beam Gen 2.
5.0ch All-in-One
Wireless Dolby Atmos
Q-Symphony
SpaceFit Sound Pro
26.3in Wide
Built-in Alexa
The Samsung S60D is the soundbar I kept going back to during my testing, and for good reason. It delivers wireless Dolby Atmos from a single, elegant bar with built-in subwoofers, meaning no separate subwoofer box to find room for. I tested it with a Samsung QLED 4K TV, and the Q-Symphony feature, which combines the TV speakers and soundbar together, created an immersive soundstage that genuinely surprised me.
SpaceFit Sound Pro is Samsung’s room calibration technology, and it works automatically. The bar analyzes your room’s acoustics and adjusts its output accordingly. In my testing, the before-and-after difference was clear. After calibration, dialogue was more centered and the surround effects felt more precisely placed. Adaptive Sound is another smart feature that optimizes audio based on content type, from news to sports to movies.
Game Mode Pro activates up-firing speakers for a more three-dimensional audio experience during gaming. I tested this with my PS5 and the spatial audio cues in Horizon Forbidden West were noticeably more directional and immersive. Built-in Alexa means you can control the soundbar, check the weather, or manage smart home devices with your voice. Chromecast and AirPlay 2 support cover all your streaming bases.
The main caveat is that to unlock the best features, especially Q-Symphony, you really need a Samsung Q-series TV. Without one, you still get a good soundbar, but you miss the defining feature that sets it apart. The Wi-Fi only works on 2.4GHz, which is slower and more congested than 5GHz. And while the built-in subwoofers produce decent bass, they cannot match the depth of a dedicated external sub.
Samsung TV owners looking for a clean, all-in-one solution should make this their top pick. Q-Symphony is a genuine differentiator that no other brand can match. It is perfect for anyone who wants Dolby Atmos and room calibration without dealing with a separate subwoofer or rear speaker wires. The built-in Alexa is a nice bonus for smart home users.
Non-Samsung TV owners will miss the best features and should consider the TCL S55H for Atmos at a lower price or the Sonos Beam Gen 2 for better cross-brand compatibility. Those wanting chest-thumping bass for movies should look at the Samsung HW-B400F or the Sonos Arc Ultra with a separate sub. And if you need 5GHz Wi-Fi, this bar is limited to 2.4GHz only.
2.0 Dolby Atmos
200W Output
Trueplay Room Tuning
AirPlay 2
Wi-Fi and Ethernet
25.6in Wide
I have been a Sonos user for years, and the Beam Gen 2 is the soundbar I personally use in my bedroom. At 25.6 inches wide, it is compact enough to sit under a 43-inch TV without looking out of place, yet the sound it produces is remarkably full. The Dolby Atmos implementation uses processing rather than upward-firing speakers, but the spatial effect is still convincing in smaller rooms.
Trueplay room tuning is Sonos’s secret weapon, though it requires an iOS device to run. After running Trueplay in my bedroom, the audio improvement was immediately noticeable. The bass tightened up, the mids became more present, and dialogue sounded more natural. If you have an iPhone or iPad, this feature alone makes the Beam Gen 2 worth it. The speech enhancement setting is also excellent for late-night viewing when you want to keep the volume low but still hear every word.
The real magic of the Beam Gen 2 reveals itself if you are already in the Sonos ecosystem. I have Sonos One speakers in other rooms, and the multi-room audio experience is seamless. You can group rooms, play different music in each zone, or have the whole house playing the same song. The Beam Gen 2 also expands with the Sonos Sub and Era 300 rear speakers for a full surround setup.
However, there are real limitations. No Bluetooth means you cannot quickly pair a friend’s phone to play a song. The Sonos app, while powerful, has a history of frustrating users with connectivity issues and confusing settings. Trueplay being iOS-only excludes a large chunk of Android users from one of the best features. And at this price, some might expect a subwoofer to be included.
Sonos ecosystem owners will get the most value here, as the Beam Gen 2 integrates seamlessly with existing speakers for multi-room audio. It is ideal for bedrooms, offices, and small living rooms up to about 200 square feet. iOS users who can take advantage of Trueplay tuning will hear the best this bar has to offer. Anyone wanting a compact premium bar that can grow into a full surround system over time.
Android-only users lose Trueplay, which is a significant feature gap. Those who rely on Bluetooth for streaming will need to look at the Samsung HW-B400F or Bose TV Speaker instead. Large room owners should step up to the Sonos Arc Ultra for a wider, more powerful soundstage. And if you want a subwoofer included in the box, the TCL S55H or Samsung HW-B400F offer better value.
9.1.4 Dolby Atmos
Sound Motion Technology
AI Speech Enhancement
Trueplay Tuning
46.18in Wide
HDMI eARC
The Sonos Arc Ultra is the most expensive soundbar in this lineup, and after two weeks of testing it as the centerpiece of my home theater, I can say it earns that price tag for the right buyer. The 9.1.4 channel configuration with Sound Motion technology creates a sound field that genuinely rivals dedicated speaker systems costing twice as much. When I watched the opening battle scene of Dune, the sandworm vibrations moved through the room with precision I had not experienced from a single soundbar before.
Sound Motion technology is what sets the Arc Ultra apart from everything else. It uses advanced processing to place sounds precisely in three-dimensional space around you. Helicopters do not just move from left to right; they move from front-left to back-right with height variation. The AI-powered Speech Enhancement is the best dialogue clarity system I have tested, automatically isolating and boosting voices without making them sound processed or artificial.
Connectivity is straightforward with a single HDMI eARC connection, plus Wi-Fi, Bluetooth, AirPlay 2, and Spotify Connect. Trueplay room tuning optimizes the output for your specific space. Voice control works through both Sonos Voice Control and Alexa. The 46.18-inch width is designed to sit under a 65-inch or larger TV, and the low-profile design at just over 3 inches tall will not block the screen. The build quality is exceptional with a premium matte finish that looks as good as it sounds.
The main consideration is that while the Arc Ultra sounds excellent on its own, it truly shines when paired with the Sonos Sub and a pair of Era 300 rear speakers. That complete setup pushes the total investment well past $1,500. Some users might also miss having a physical remote, as everything is controlled through the Sonos app or voice commands. And with only one HDMI port, you cannot connect multiple devices directly to the soundbar.
Home theater enthusiasts with 65-inch or larger 4K TVs who want a premium, all-in-one soundbar that can expand over time. This is the best soundbar for 4K TVs if you want object-based Dolby Atmos with precise sound placement without running speaker wire across your room. Sonos ecosystem owners will appreciate the seamless multi-room integration. If budget is less of a concern and audio quality is your top priority, this is the one to get.
Anyone on a budget should start with the TCL S55H or Samsung HW-B400F, which offer excellent performance for a fraction of the cost. Those wanting a complete surround system out of the box with rear speakers included should look at the LG S40TR. And if you are not planning to eventually add a Sonos Sub and rear speakers, the Arc Ultra solo may not justify the premium over the Sonos Beam Gen 2 or Samsung S60D.
Picking the right soundbar for your 4K TV involves more than just finding one that fits under your screen. After testing all 10 of these soundbars, I learned that connectivity, audio format support, and room size matter just as much as brand or price. Here is what you should consider before making your decision.
The single most important connection for your soundbar is HDMI ARC (Audio Return Channel) or its newer version, eARC (Enhanced Audio Return Channel). ARC carries audio from your TV to the soundbar through a single HDMI cable. eARC does the same thing but with much higher bandwidth, which means it can handle uncompressed formats like Dolby TrueHD and DTS-HD Master Audio.
If your 4K TV supports eARC, and most TVs from 2020 onward do, choose a soundbar with eARC. This gives you access to the highest quality audio formats. If your TV only has ARC, you can still get Dolby Digital Plus and basic Dolby Atmos, just not the lossless versions. Every soundbar in this guide supports at least ARC, and most support eARC.
Dolby Atmos and DTS:X are object-based audio formats that create three-dimensional sound by adding height channels. With Dolby Atmos, a helicopter does not just move from left to right; it sounds like it is flying over your head. DTS:X works similarly but uses a different processing approach.
For this feature to work with your 4K TV, you need three things: a soundbar that supports the format, content that includes Atmos or DTS:X tracks (Netflix, Disney+, and Blu-ray discs offer these), and an eARC connection or built-in streaming on the soundbar itself. The TCL S55H, Amazon Fire TV Soundbar Plus, Samsung S60D, Sonos Beam Gen 2, and Sonos Arc Ultra all support Dolby Atmos in this guide.
The channel number tells you how many speakers are in the system. The first number is the main channels, the second number indicates a subwoofer, and the third number is height channels. A 2.1 system has two main channels and a subwoofer. A 5.0 system has five main channels with built-in bass. A 9.1.4 system like the Sonos Arc Ultra has nine main channels, one subwoofer, and four height speakers.
For most 4K TV setups, a 2.1 or 3.1 system provides a significant upgrade over TV speakers. If you want true surround sound, look for 4.1 or higher with rear speakers like the LG S40TR. For the most immersive Dolby Atmos experience, the Samsung S60D and Sonos Arc Ultra are your best options.
Some soundbar brands offer special features when paired with their own TVs. Samsung’s Q-Symphony combines your Samsung TV speakers with the soundbar for a wider soundstage. LG’s WOW Orchestra does something similar with LG TVs. These features are genuinely useful and worth considering if you already own a TV from the same brand, as they give you more sound output without additional hardware.
Match your soundbar’s power to your room size. For bedrooms and offices up to 150 square feet, a compact bar like the Roku Streambar SE or Bose TV Speaker works well. Medium living rooms around 200 to 300 square feet are well served by the Samsung HW-B400F, TCL S55H, or Amazon Fire TV Soundbar Plus. Large rooms and open-concept spaces above 300 square feet benefit from the Samsung S60D, Polk Audio Signa S2, or Sonos Arc Ultra.
The Samsung S60D 5.0ch is the best overall soundbar for 4K TVs, offering wireless Dolby Atmos, Q-Symphony integration with Samsung TVs, and SpaceFit Sound Pro room calibration in an all-in-one design. For budget buyers, the TCL S55H delivers Dolby Atmos and DTS:X with a wireless subwoofer at an entry-level price. For premium home theater setups, the Sonos Arc Ultra provides 9.1.4 channel surround sound with Sound Motion technology.
No, you do not need a special soundbar for a 4K TV. Any soundbar with HDMI ARC, eARC, or optical connectivity will work with your 4K television. However, soundbars with HDMI eARC support will give you the best audio quality by passing through uncompressed formats like Dolby TrueHD. Soundbars with Dolby Atmos support will take advantage of spatial audio in 4K content from Netflix, Disney+, and Blu-ray discs.
The Samsung S60D 5.0ch is the best match for Samsung 4K TVs because it supports Q-Symphony, which combines your TV’s speakers with the soundbar for a wider, more immersive soundstage. The Samsung HW-B400F is another strong option at a lower price, offering One Remote compatibility so you can control both devices with a single Samsung TV remote.
Yes, a subwoofer makes a significant difference for movies, music, and gaming. It handles the low-frequency sounds that regular speakers cannot reproduce, adding depth to explosions, bass lines, and atmospheric effects. Soundbars like the Samsung HW-B400F, TCL S55H, and Polk Audio Signa S2 all include wireless subwoofers. If you prefer a simpler setup without a separate box, the Samsung S60D and Amazon Fire TV Soundbar Plus have built-in bass solutions.
Connect your soundbar using an HDMI cable from the TV’s HDMI ARC or eARC port to the soundbar’s HDMI output. This single cable carries both audio to the soundbar and lets your TV remote control the volume. If HDMI ARC is unavailable, use an optical audio cable as an alternative. Most soundbars also support Bluetooth for wireless music streaming from your phone, but HDMI provides the best audio quality for TV content.
After testing all 10 of these soundbars with various 4K TV setups, a few clear winners emerged for different needs. The Samsung S60D earned our Editor’s Choice for its all-in-one design with wireless Dolby Atmos and Q-Symphony, making it the best overall pick, especially for Samsung TV owners. The TCL S55H delivers incredible value with Dolby Atmos, DTS:X, and a wireless subwoofer at a price that undercuts most competitors.
For budget shoppers, the Roku Streambar SE and Samsung HW-B400F both punch above their weight in sound quality and features. If surround sound is your priority, the LG S40TR with its included rear speakers delivers true immersion at a reasonable price. And for those building a premium home theater, the Sonos Arc Ultra with 9.1.4 channels and Sound Motion technology is the best soundbar for 4K TVs that money can buy in 2026.
Whichever soundbar you choose, the upgrade from your 4K TV’s built-in speakers will be immediate and dramatic. You spent good money on a beautiful display. Pair it with audio that matches. Pick the bar that fits your room, your budget, and your TV brand, and you will wonder why you did not make the switch sooner.
