Compare JBL Bar 500 MK2 Soundbar vs KEF LSX II Wireless HiFi Speakers

Reviewers liked the broad finish selection, from fabric and satin options to bolder colors, though LT models sacrifice some luxury finishes.

Reviewers repeatedly praise calibration as quick and useful, with automatic room tuning or one-button calibration called out as an easy way to improve the sound.

AirPlay support is consistently present, with reviewers grouping it among the major streaming and casting options.

AirPlay support is repeatedly listed as part of the LSX II wireless streaming suite.

One reviewer highlights 750 W total system power, supporting the impression that the bar-sub package has substantial output for home theater use.

The built-in active amplification is consistently treated as a strength, with 200W total power or separate amp channels noted across reviews.

App feedback is mixed: one review says the JBL One app connected and updated easily, while others mention limited in-app streaming and EQ settings that do not save.

Most app comments are positive, especially setup and responsiveness, but one review cites slow Chromecast response and another notes missing multi-room sync.

Format support is good but not unanimous: reviewers cite Dolby Atmos and DTS Virtual X on the MK2, while one transcript says there is no DTS support.

High-resolution format support is strong, with reviews citing PCM up to 24-bit/384kHz plus DSD and MQA support depending on model.

Bluetooth streaming is mentioned positively in owner use, but there is limited direct evidence about long-range or stress-test stability.

Bluetooth range evidence is limited and mixed, with one review wishing for Bluetooth 5.0 mainly for extra range while noting Wi-Fi makes range less critical.

Build evidence is positive where reviewed, with rigid construction, durable materials and well-made cabinets noted by several sources.

Chromecast and Google Cast support are repeatedly listed as built-in streaming options across reviews.

Chromecast support is widely confirmed, although one LT review reports slow track loading through Chromecast.

System cohesion is mixed: the bar-sub package can elevate the experience, but one reviewer hears a gap between the subwoofer and soundbar.

Reviewers describe the presentation as coherent, organized and balanced, especially in near-field or small-room use.

Design impressions are broadly positive, emphasizing a low-profile, discreet bar with minimal branding and, in one review, a new white finish.

Design is a major strength, with reviewers calling the speakers stylish, elegant, compact and visually premium.

Build quality is acceptable rather than premium: reviewers mention the compact low bar and plastic/aluminum-style construction that still feels solid.

Detail retrieval gets positive remarks, especially for movie effects and small audio nuances that stand out clearly.

Detail retrieval is consistently strong, with reviewers hearing clear separation, transparent presentation and fine instrumental texture.

Dialogue clarity is one of the strongest themes, with several reviewers saying voices are clear, easy to understand, or helped by PureVoice.

For TV and movies, reviewers generally report crisp dialogue and clearer voices, though home-theater scale still depends on use case.

High-volume behavior is mixed: some reviewers hear no distortion, while others note brittle, harsh or strained treble when pushed.

Dolby Atmos performance is generally effective for a bar, though reviewers note the height effect is virtual and less dramatic without up-firing drivers.

Dynamic ability is strong for room-filling impact, but bass speed can lag on fast rhythms according to one review.

Dynamic performance is praised for punch, rhythm and clean leading edges, though deep bass and extreme output remain limited by size.

EQ customization is available through the app or controls, but one reviewer criticizes the lack of saved presets and unsaved EQ behavior.

The KEF app offers meaningful EQ and placement adjustments, including Normal and Expert modes and subwoofer tuning.

The tonal balance is warm and bass-rich; reviewers like the fullness, though some note slower or less seamless bass integration.

Tonal balance is widely praised as accurate and controlled, but several reviewers note brightness, bass limits or EQ sensitivity.

Gaming passthrough is useful for basic console hookup but limited, with reviewers warning that 4K passthrough is capped and not HDMI 2.1.

Google compatibility is present through Google Cast/Home mentions, with one review noting external voice-control dependence.

Google-related support appears through Chromecast compatibility across multiple reviews.

HDMI 2.1 gaming support is a weakness because reviews state the HDMI input is not HDMI 2.1 or is limited to 4K/60.

Gaming over HDMI is limited by the product’s ARC-only implementation rather than newer eARC or immersive-format support.

HDMI ARC/eARC is consistently useful, with reviewers saying it is included and simple for TV hookup.

HDMI ARC is a repeated strength for TV use, with reviewers valuing simple TV connection and remote-volume convenience.

Home theater integration is a strength, helped by HDMI connectivity, TV remote control behavior, passthrough, and console/disc-player flexibility.

The LSX II works well as a compact TV or 2.0 home-theater system, but reviewers repeatedly caution that surround immersion and deep bass are limited.

The wireless subwoofer connection is treated as a practical benefit because placement is flexible without running speaker cable.

Inter-speaker connectivity is model-dependent: standard LSX II can use wired or wireless links, while LT versions require a cable.

TV latency is generally strong, with reviewers reporting no sync issues or virtually no lag.

Maximum loudness is a strength, with reviewers citing 750 W output, room-filling sound, and more volume than they needed.

Maximum volume is impressive for the size in desktops and small to mid-size rooms, but very loud living-room bass is a limitation.

Low-volume listening benefits from PureVoice, especially for nighttime or apartment use where dialogue still needs to stand out.

Low-volume evidence is limited but mixed, with one reviewer saying dynamics drop too low and another still feeling bass at lower levels.

Microphones are discussed mainly for calibration, not calls or voice capture, but reviews confirm built-in/top microphones for room analysis.

Multi-speaker pairing is supported through JBL grouping or Oriccast-style linking, though reliability is not deeply stress-tested.

Multi-speaker or multi-room evidence is mixed, with some KEF multi-room control support but no synchronized multi-room playback in the app.

Uni-Q dispersion earns strong praise for reducing the sweet-spot problem and preserving stereo image off axis.

On-device controls are basic and accessible, with volume/source controls mentioned, though one reviewer dislikes the input button behavior.

On-device controls are a weakness because reviewers repeatedly note the absence of speaker touch controls or controls on the cabinets.

Optical input is consistently listed as a supported wired option alongside HDMI connections.

Optical input support is repeatedly listed among the wired connection options.

Price impressions are mixed but favorable overall: reviewers call it high, yet often reasonable given the included amps, streaming and sound.

Remote usability is positive overall, described as simple or useful, with phone remote control also available through the app.

Remote usability is mixed, from useful and ergonomic to cheap-feeling, plasticky, or lacking source controls.

Setup is repeatedly described as simple, from easier app connection to basic power/HDMI hookup and one-button calibration.

Setup simplicity is a clear strength, with multiple reviewers calling the process smooth, quick or plug-and-play.

Smart assistant integration exists through Alexa/Google compatibility, but one reviewer notes assistants are not built into the soundbar itself.

Smart features are broad, including streaming services, app control, casting, room calibration, and multi-room playback options.

Smart features are broad, especially streaming services, app control, Roon support on standard LSX II, and flexible source handling.

Height presentation is the main Atmos compromise: it creates some height, but several reviews stress there are no dedicated up-firing drivers.

Soundstage height and depth are praised in near-field use, with reviewers hearing images above, behind and layered between speakers.

Spotify Connect is strongly supported where tested, including a review that says it works seamlessly.

Spotify Connect support is repeatedly confirmed as part of the streaming feature set.

Status feedback is a strong usability point, with reviewers appreciating clear built-in displays or plain-English indicators.

Status feedback is handled by LED or light-ring indicators rather than elaborate lighting.

Stereo imaging is praised in one review for centered vocal effects and a stable image.

Stereo imaging is one of the most consistent strengths, with reviewers praising placement, layering, precision and wide soundstage behavior.

The subwoofer is one of the product's clearest strengths, repeatedly described as powerful, deep, physical, and central to the experience.

Subwoofer integration is strong, with outputs and app crossover settings available, and several reviewers recommending a sub for deeper bass or movies.

Surround simulation is widely praised for spreading sound around the room, though it remains simulated rather than rear-speaker surround.

Surround simulation is weak because reviewers explicitly note that these stereo speakers do not provide immersive surround formats.

Value is a major positive theme, especially in reviews calling it affordable, best-in-test, or a strong buy around $500 or less.

Value is viewed positively when considering the all-in-one design, sound quality, and cheaper LT alternative, even when the initial price is high.

Video passthrough is useful, with HDR10+/Dolby Vision or 4K Dolby Vision mentioned, but gaming bandwidth limits remain a caveat.

Voice clarity is generally strong, with reviewers saying voices are emphasized clearly and stand out without strain.

Voice and vocal clarity are generally strong, with centered vocals and dialogue-forward presentation, though one comparison notes weaker intelligibility than a rival.

Weight and size convenience are mixed: the bar is compact, while the subwoofer is heavy enough to place once and leave alone.

The compact footprint and modest weight make placement and room-to-room movement easier than traditional systems.

Wireless streaming is generally positive through Wi-Fi and casting, although one reviewer notes the lack of Ethernet could matter in weak Wi-Fi rooms.

Wi-Fi streaming is generally reliable in reviewer use, with one review noting no network problems and another calling wireless performance good.

Wired inputs are flexible, with reviewers citing HDMI/eARC, optical, USB, and even Ethernet or flash-drive playback depending on the transcript.

Wired input support is extensive across reviews, including HDMI ARC, optical, USB-C, analog aux on standard LSX II, Ethernet and subwoofer output.
