The Best Soundbars by Use Case
Best for a Slim Atmos Setup: TCL Design Series Bang & Olufsen A65K
The TCL Design Series Bang & Olufsen A65K pairs a 3.1.2-channel layout with a wireless subwoofer, making it a fit for viewers who want height effects and a dedicated center channel without separate rear speakers. Its listing specifies Dolby Atmos and DTS:X support, plus AI Sonic Auto Calibration. The slim profile may also suit a setup where a bulky bar would compete with the TV or furniture.
Reasons to buy:
- Dedicated center channel supports clearer dialogue.
- Up-firing height channels support Atmos and DTS:X effects.
- Wireless subwoofer adds a separate bass component.
Reasons to avoid:
- It does not list detachable or separate rear surround speakers.
- Check TV placement and available connections against the full product listing before ordering.
Skip it if you specifically want physical surround speakers positioned behind your seat.
Best for Sonos Expansion: Sonos Beam Gen 2 – Black
The Sonos Beam Gen 2 – Black suits listeners who want a compact soundbar that can grow into a larger Sonos setup. The listing highlights Dolby Atmos, Wi-Fi, Ethernet, AirPlay 2, HDMI eARC, and the option to expand with a Sonos Sub Mini and rear speakers. Trueplay tuning is included, while control options include the Sonos app, TV remote, AirPlay 2, and voice.
Reasons to buy:
- Expandable with compatible Sonos Sub Mini and rear speakers.
- Supports Wi-Fi, Ethernet, AirPlay 2, and HDMI eARC.
- Can stream music, radio, podcasts, and audiobooks when the TV is off.
Reasons to avoid:
- The listing describes a five-driver soundbar, not a package with a separate subwoofer or rear speakers.
- Verify your TV has HDMI eARC if you want to use that connection.
Skip it if your priority is a bundled wireless subwoofer and physical rear speakers from the start.
Best All-in-One for Streaming: JBL Bar 300MK2-5.0 Channel All-in-one soundbar
The JBL Bar 300MK2-5.0 Channel All-in-one soundbar is designed for buyers who want a wide soundstage and streaming support without adding a separate subwoofer. Its listing specifies Dolby Atmos, MultiBeam 3.0, and built-in bass ports, along with AirPlay, Google Cast, Spotify Connect, Tidal Connect, and Roon Ready. PureVoice 2.0 is intended to improve dialogue audibility, and the JBL ONE app provides sound customization.
Reasons to buy:
- All-in-one design avoids a separate subwoofer.
- Multiple listed streaming services and connection ecosystems.
- Room calibration and adjustable equalizer through the JBL ONE app.
Reasons to avoid:
- It has no separate wireless subwoofer in the published product details.
- Built-in bass ports may not suit buyers seeking a dedicated subwoofer component.
Skip it if deep bass from a separate subwoofer is a central part of your movie setup.
Best for Detachable Surround Speakers: JBL Bar 700: 5.1-Channel soundbar with Detachable
The JBL Bar 700: 5.1-Channel soundbar with Detachable offers a distinct setup for viewers who want rear-channel sound without permanent speaker wiring. Its two detachable surround speakers are battery-powered, and the listing pairs them with Dolby Atmos and a 10-inch wireless subwoofer. Built-in Wi-Fi, AirPlay, Alexa Multi-Room Music, and Chromecast are also specified for streaming.
Reasons to buy:
- Detachable speakers provide physical surround channels without extra power connections at their rear positions.
- Includes a 10-inch wireless subwoofer according to the listing.
- Supports several named music and streaming ecosystems.
Reasons to avoid:
- Detachable speakers are battery-powered, so placement and charging routine matter.
- Confirm you have room to position the surround speakers when watching.
Skip it if you prefer a single soundbar with no speakers to move or maintain.
Best for Adjustable Dialogue and Bass: Polk Audio Signa S4 Dolby Atmos 3D Sound Bar
The Polk Audio Signa S4 Dolby Atmos 3D Sound Bar is a practical fit for TV viewers who want a dedicated wireless subwoofer and direct control over voice and bass levels. The listing specifies a seven-driver array, a center channel, up-firing height speakers, HDMI eARC, and Polk VoiceAdjust and BassAdjust features. Its stated slim profile may help when a soundbar needs to sit in front of a screen, though buyers should check their own TV stand clearance.
Reasons to buy:
- VoiceAdjust lets listeners change voice levels.
- BassAdjust provides separate bass control.
- Includes a wireless subwoofer and up-firing height speakers.
Reasons to avoid:
- The published details do not describe physical rear surround speakers.

Also Considered
The LG SC9S 3.1.3-Channel Perfect Matching Soundbar may suit owners of an LG OLED evo C Series TV who want listed WOW Orchestra and WOW Interface features, but its TV-specific positioning makes it less universal as a general pick.
The WiiM Bar 3.0.2 Dolby Atmos & DTS Smart Soundbar stands out for its touchscreen, RoomFit, and stated expansion path to a wireless 5.1.2 system, though compatible surrounds and subwoofer are sold separately.
The JBL Bar 500MK2-5.1 Channel soundbar System may fit buyers seeking a 10-inch wireless subwoofer, Dolby Atmos, and dialogue enhancement, but the published details do not list detachable physical surround speakers.
The ULTIMEA Skywave X50 5.1.4ch Wireless Surround may appeal to shoppers seeking a bundled multi-speaker system with wireless surrounds and an 8-inch subwoofer, but its many listed system claims merit careful compatibility checks.
How to Choose the Best Soundbar Under $500
Choose the surround layout for your room
Channel numbers describe speaker-channel arrangements, but they do not mean every system uses separate speakers around the room. A 3.1.2 model such as the TCL has height channels and a subwoofer channel, while the JBL Bar 700 lists detachable surround speakers. An all-in-one bar such as the JBL Bar 300MK2 uses MultiBeam processing for a wide soundstage instead.
For overhead effects, look for explicitly listed up-firing speakers and Dolby Atmos support, then consider ceiling height and room layout. Reflected sound depends on the room, so do not treat an Atmos label as proof of identical results in every space. If physical sound behind you matters more, prioritize models listing rear or detachable surrounds.
Decide whether a separate subwoofer matters
A separate wireless subwoofer can add a dedicated low-frequency component, but it also needs floor space and a nearby power outlet. TCL, Polk, and JBL Bar 700 list wireless subwoofers; JBL Bar 300MK2 instead describes built-in bass ports and no separate subwoofer in the published details.
Think about what you watch and where the subwoofer could sit. Action films and bass-heavy music may make a separate subwoofer attractive, while a compact room or a preference for fewer components may favor an all-in-one bar. Listed wattage alone does not establish how a system will sound in your room.
Check dialogue features and controls
A center channel and dialogue adjustment can help when voices are hard to follow at the volume you prefer. The TCL and Polk list dedicated center-channel designs, while JBL specifies PureVoice 2.0 on the Bar 300MK2. Sonos describes clear dialogue, but the published details do not specify a user-adjustable dialogue control for Beam Gen 2.
Look for the exact control you need, not just broad claims about clarity. Voice-level adjustment, a dialogue mode, and a center channel are different features. If you watch at night, check whether a night mode or loud-effects management is listed; the WiiM Bar specifies Night Mode and AI Dialog Enhancement.
Match connections and streaming to your devices
Check the TV’s ports before choosing. HDMI eARC appears in the published details for Sonos Beam Gen 2 and Polk Signa S4, among others, but confirm the exact connection requirements in the product listing and your TV manual. The ULTIMEA Skywave X50 lists 4K HDR pass-through, a feature relevant when routing a source through the soundbar; verify supported formats and connection behavior for your devices.
Streaming features also vary. Sonos lists AirPlay 2, Ethernet, Wi-Fi, and app control. JBL Bar 300MK2 names AirPlay, Google Cast, and several music services. Choose based on the services and devices you already use, and confirm that your preferred control method is supported.
Consider setup, space, and future expansion
Measure the space below the TV and check whether the soundbar could cover the screen edge or remote sensor. Also account for a subwoofer’s placement and any rear speakers that need to sit near your listening position. Polk describes its bar as slim, but confirm dimensions in the current listing before making a close-fit purchase.
If you want to build a system gradually, compare the named expansion options rather than assuming products from one brand work together. Sonos lists compatibility with its Sub Mini and rear speakers; WiiM describes expansion with compatible WiiM surrounds and a subwoofer sold separately. Check the specific devices and requirements before buying add-ons.
How We Compared
This comparison uses the published product listings, including stated channel layouts, speaker arrangements, connection options, streaming support, dialogue controls, and expansion details. The guide separates listed features from listening outcomes, which can vary with room layout, TV compatibility, placement, and personal preference. No customer feedback was supplied for these products, so the recommendations rely on listed specifications and design details rather than review patterns.
Frequently Asked Questions
Will any of these soundbars work with my TV?
Compatibility depends on the TV’s available connections and the soundbar’s requirements. Check the soundbar listing and TV manual for HDMI eARC or other supported audio connections. Polk states that Signa S4 works with TVs including 8K, 4K, and HD sets, but you should still verify the connection method for your specific TV.
Do Dolby Atmos soundbars need rear speakers?
No. Several listed bars use up-firing speakers or sound processing to create height or surround effects without rear speakers. The JBL Bar 700 specifically includes detachable surround speakers, while other models describe Atmos support without listing physical rear speakers. Choose based on whether you want virtualized effects or speakers placed behind you.
Is a soundbar with a wireless subwoofer always the better choice?
Not for every room or listener. A separate subwoofer adds a dedicated bass component but takes up space and adds another unit to place. An all-in-one model can simplify the setup, though it does not offer the same separate subwoofer arrangement described by the TCL, Polk, and JBL Bar 700 listings.
What does HDMI eARC do for a soundbar setup?
HDMI eARC is a connection feature listed on several models, including Sonos Beam Gen 2 and Polk Signa S4. To use it, both the soundbar and TV need compatible ports, and the connection should follow the manufacturers’ instructions. Check your TV manual rather than assuming every HDMI port supports eARC.
Can I expand a soundbar system later?
Some models list specific expansion paths. Sonos Beam Gen 2 can be expanded with a compatible Sonos Sub Mini and rear speakers, while WiiM describes adding compatible WiiM surrounds and a subwoofer to reach a wireless 5.1.2 setup. Confirm which accessories are compatible and whether they are sold separately before planning a future upgrade.
