Compare KEF LS50 Wireless II Powered Bookshelf Speakers vs Edifier M90

AirPlay 2 receives positive evidence in the one review that tested it, where streaming from an iPhone worked seamlessly.

AirPlay 2 is absent, so the M90 cannot join an Apple multi-room setup and must rely on Bluetooth or wired connections.

HDMI ARC/eARC evidence is split: some reviewers report flawless integration, while others report Samsung or HDMI connection failures.

HDMI eARC is a standout strength, delivering simple TV setup, reliable CEC volume control, and strong audio quality. It makes the M90 a convincing alternative to a compact soundbar.

Weight is a practical drawback, with reviewers noting the speakers are heavy or hard to handle alone.

The speakers have reassuring heft but retain a compact, desk-friendly footprint. They are easy to position on shelves or media consoles without feeling flimsy.

The main backwards-compatibility concern is long-term software support for earlier wireless LS50 owners and whether app support will continue.

AUX and optical inputs make it easy to use turntables with preamps, older media players, and legacy televisions.

Remote-control evidence is mixed to negative overall, with complaints about cheap feel, poor tactile cues, and reliance on the app.

The compact radio remote is highly useful for volume, inputs, playback, and EQ presets, and it works without line of sight. Because the physical controls are on the rear, the remote becomes nearly essential.

Wi-Fi streaming reliability is mixed: AirPlay/Chromecast can work seamlessly, but other evidence reports Wi-Fi glitches and dropouts.

There is no Wi-Fi streaming, direct music-service support, or multi-room playback, which is a notable limitation for shoppers wanting a networked speaker.

On-device controls are praised in limited evidence for looking elegant and integrating well with the speaker surface.

The only physical knob and power control sit on the rear of the active speaker, making direct adjustments awkward. Most users will rely on the remote, app, or TV remote instead.

Inter-speaker connection evidence is mixed, ranging from rock-solid pairing to dropouts or brief left/right startup mismatch.

The generously long speaker-to-speaker cable allows proper stereo spacing across desks, shelves, and TV stands.

TV latency is praised in the one review that tested dialog-heavy content, where audio and video stayed in sync.

HDMI eARC provides responsive, well-synced TV and gaming audio. One customer encountered noticeable Bluetooth video delay, so wired TV use is the safer choice.

Bluetooth stability is praised in one review as part of a connectivity package where everything just worked.

Pairing is usually fast and stable at normal room distances. An isolated customer report found repeated disconnections when using Bluetooth with a TV.

The tonal balance is usually praised as clean, neutral, clear, and well controlled, though some reviewers find it clinical or not warm.

The overall tuning is warm-neutral or broadly balanced, with strong bass and clear vocals. Depending on preset and placement, the mid-high range can sound cool, dry, recessed, or slightly rough, making the nine-band EQ especially useful.

Bluetooth codec support earns positive evidence from aptX playback being judged high quality despite Bluetooth’s lossy nature.

LDAC provides unusually strong wireless quality for this class, while AAC keeps iPhone playback respectable. LDAC is unavailable on Apple devices and cannot be used simultaneously with multipoint.

Value evidence is split but broadly positive: many reviewers call the performance strong for the money, while some prefer cheaper separates or alternatives.

The combination of sound quality, HDMI eARC, broad inputs, app EQ, and compact size makes the M90 strong value as an all-in-one system. One customer preferred a much cheaper alternative, but the wider consensus is highly favorable.

Maximum volume is praised as surprisingly loud for compact speakers, though one reviewer notes SPL limits compared with larger systems.

The M90 gets far louder than most desktop setups require and comfortably fills small to medium rooms. Output remains impressive in larger spaces, though the compact drivers cannot match full-size speakers.

Cabinet construction is praised for inert, well-braced, refined build that supports low coloration.

The dense MDF-style cabinets feel solid, rigid, and more premium than typical computer speakers. One unit showed average panel fit, but most found the enclosure impressively substantial.

The top touch controls receive positive evidence in the one review that evaluated their responsiveness.

The remote buttons respond quickly, have practical sizing, and remain easy to use in a dark room.

Low-volume performance has limited but positive evidence from soft piano notes still conveying scale and power.

Detail and clarity remain intact at apartment-friendly listening levels, making the M90 especially effective for quiet desktop use.

Setup evidence is polarized: many reviewers call it easy or guided, while others find the initial app/Google Home process frustrating.

Most setups are plug-and-play, with USB-C and HDMI working in minutes. Docking-station arrangements and the app's Bluetooth connection can require extra troubleshooting or clearer instructions.

Detail retrieval is one of the strongest themes, with reviewers repeatedly hearing fine texture, layering, micro-detail, and clarity.

Vocals, instruments, and small textures are generally clear and well separated. The smooth upper treble can occasionally blend fine details on dense recordings.

Reviewers consistently describe the presentation as integrated, cohesive, and naturally held together.

Drivers blend smoothly into a unified, clean presentation, with vocals and instruments remaining organized across music, games, and video.

Wired input flexibility is generally praised, though the missing USB input is a drawback for desktop use.

HDMI eARC, optical, USB-C, AUX, and sub-out cover nearly every desktop, TV, and legacy source. Multiple devices can remain connected and be switched without moving cables.

Subwoofer evidence is context-dependent: some reviewers say the speakers do not need one for music, while movie or bass-focused setups benefit from adding one.

The dedicated sub output makes it easy to add deeper extension. Many desktop listeners will be satisfied without one, while action movies and bass-heavy music benefit clearly from a subwoofer.

Review evidence praises the expanded finish choices and treats the new colors as a visual upgrade rather than a functional change.

The black and white matte finishes look clean, modern, and easy to match with a desk or TV stand. The surfaces resist fingerprints and everyday marks well.

High-resolution format support is generally viewed as useful and broad, though one reviewer heard no practical difference between very high sample-rate files.

Hi-res wired processing and LDAC playback preserve more detail than basic Bluetooth, with a clearly audible benefit on compatible high-resolution material.

Soundstage size is praised for width, depth, and height, though one reviewer finds width weaker than depth.

The M90 produces unusually wide, deep, and tall staging for its size, especially over HDMI or optical and with careful placement.

Stereo imaging is a major strength, with repeated praise for precise placement, separation, and stable images.

The speakers create a wide, stable stereo image with convincing center vocals and precise placement. A few demanding recordings reveal less pinpoint separation than dedicated hi-fi monitors.

Dynamic ability is praised for punch, agility, and unflappable scaling at volume.

The bi-amplified design gives the compact speakers strong punch and reserve, keeping music and movie effects lively as volume rises.

Home-theater use is praised when HDMI works, with reviewers using the speakers as a simple TV or 2.1 setup.

HDMI eARC, CEC, clear dialogue, and wide stereo imaging make the M90 an excellent bedroom or office TV upgrade. Larger rooms and effects-heavy movies may still need a subwoofer or bigger speakers.

Design evidence is strongly positive, with repeated praise for the looks, finishes, compact style, and visual attention to detail.

The restrained, boxy design looks modern and purposeful without flashy styling. It blends easily into desks and living rooms, although the busy rear panel is less elegant.

EQ and room-tuning controls are praised for allowing meaningful bass, treble, room, and subwoofer adjustments.

The nine-band EQ and saveable presets make meaningful tonal and room corrections easy, with presets accessible from the remote. Power users may miss full parametric EQ, and some changes require a Bluetooth app connection.

App evidence is mixed: several reviewers call KEF Connect easy, reliable, or improved, while others report frustrating setup or connection losses.

ConneX is usually fast, clear, and stable, with useful input, firmware, and EQ controls. It can feel basic, sometimes requires Bluetooth for changes, and a few users found reconnection or setup unnecessarily fiddly.

Voices and vocals are repeatedly praised as realistic, intelligible, clear, and precisely placed.

Voices sound clear, forward, and full-bodied across music, podcasts, and TV. They remain intelligible without becoming shouty or thin.

Price evidence is mixed: reviewers call the speakers expensive or recently more costly, but several still judge them worth the money.

The regular price is a noticeable jump from the M60 and can feel high for a single-purpose desktop setup. Discounts make the proposition much easier to justify.

High-volume cleanliness is mostly praised, though one synthesis review warns control drops at concert-hall levels.

Most listeners found the sound clean and controlled even when pushed hard, with little hiss or obvious distortion. At extreme levels, bass can become boomier and a few tracks lose some composure.

The built-in amplification is presented as a major convenience because buyers do not need to match the speakers with a separate amplifier.

The active, bi-amplified design needs no separate receiver, DAC, or power amplifier, simplifying both desktop and TV systems.

Optical input receives positive evidence as a fallback that worked fine when HDMI had issues.

The optical input is handy for televisions, media players, and older digital sources. It sounds good, though it does not support the same automatic wake behavior as HDMI.

Bluetooth and HDMI wake quickly, but USB-C, optical, and AUX may require the remote or app. The aggressive default sleep behavior can interrupt quiet content, though firmware and app settings can largely fix it.

Bass is punchy, fast, and unusually authoritative for four-inch drivers, with little muddiness or bloat. Deep sub-bass and large-room impact remain limited, so bass-heavy listeners may want a subwoofer.

Bluetooth pairing is quick and straightforward, making casual phone and tablet playback easy.

The crowded rear panel can turn into a visible tangle when several sources are connected at once.

Chromecast testing is positive in the review that directly used it, with seamless playback reported.

TV and movie dialogue comes through crystal clear, nuanced, and naturally centered, even during busy scenes.

The exposed drivers have no grilles, leaving the soft tweeters vulnerable to curious fingers or accidental contact.

Directional effects are easy to track, with strong impact and spacious rendering for desktop or couch gaming. HDMI eARC also keeps TV gaming responsive.

Google-related setup is the main weakness, with reviewers calling Android/Google Home onboarding more fiddly or forced.

The box includes a generous cable selection, but a few customers received defective USB-C or power cables that required replacement.

Multipoint makes switching between two devices convenient and generally seamless. Enabling it disables LDAC, so shoppers must choose convenience or the highest Bluetooth quality.

Music sounds lively, clean, and enjoyable across genres, with rich vocals, punchy bass, and useful detail. The tuning favors accessible long-session listening over strict studio-monitor neutrality.

Dispersion and sweet-spot evidence is positive, with Uni-Q/coaxial design helping wider seating and room coverage.

The compact footprint and substantial output are an excellent match for desks, bedrooms, offices, apartments, and small to medium living rooms.

Smart-feature evidence praises the stable all-in-one platform but notes the lack of onboard voice-assistant functions.

Spotify reliability is criticized in owner-reported evidence because tracks can cut out near the end.

Status feedback is a weak point in limited evidence because one reviewer found missing volume indication frustrating.

The wide front stage gives flyovers and directional effects convincing space, but it remains a stereo system rather than true surround sound.

Recycled cardboard-style protective forms reduce packaging waste while still keeping the speakers well protected.

Highs are generally smooth, detailed, and comfortable for long sessions. Some listeners heard recessed, cool, or slightly rough upper frequencies, which the EQ can usually tame.

HDMI eARC and CEC connect reliably, wake quickly, and let the TV remote control volume and power without fuss.
