Compare Bang & Olufsen Beosound A1 Speaker 3rd Gen vs KEF Muo

EQ customization was a standout, with reviewers praising the visual sound control as helpful, easy, and unusually gratifying.

Five presets provide quick tonal changes, but the lack of a manual equalizer is one of the most repeated complaints. Several listeners wanted direct control over recessed mids or bass behavior.

Omnidirectional sound was generally positive, though one reviewer disputed true 360-degree behavior while still finding placement easy.

The Muo is primarily directional rather than truly omnidirectional. Listening from the front gives the clearest result.

Charging time was a weak spot because reviewers described the roughly three-hour charge as leisurely or on the long side.

A 15-minute charge can restore about three hours of playback, while a full charge takes roughly two hours. That combination is consistently viewed as fast and practical.

Privacy/data sentiment was lightly positive because the removal of Alexa also means Amazon’s assistant is not always listening.

The app requires an account and asks for age and gender information that feels unnecessary for a speaker. This is the clearest privacy-related concern.

On-device controls were praised as nice and clicky in direct use.

Physical controls range from solid and clicky to awkward in the dark. Hidden button combinations for stereo and USB-C modes make advanced functions less intuitive.

Physical controls were praised for positive, responsive, clicky action.

Button quality is mixed: one unit had clicky, tank-like controls, while others found the sealed buttons hard to distinguish or requiring firm presses. Low-light use is the main frustration.

General Bluetooth connectivity was mostly positive for quick pairing, but one reviewer criticized the lack of Auracast as a missed futureproofing opportunity.

Bluetooth 5.4, Fast Pair options, Auracast, and broad device support make wireless use comprehensive. Playback handled music and video smoothly in normal use.

Smart features were mixed: the app content and radio features impressed one reviewer, while another found the overall package simple rather than feature-packed.

Auracast and app control add useful modern features, but the Muo lacks Wi-Fi and has limited software depth. Auracast compatibility is also more restrictive for iPhone users.

The B&O app was repeatedly praised as responsive, simple, flexible, and among the best companion apps in the category.

The KEF Connect app reliably covers volume, inputs, battery status, presets, and updates, but most descriptions call it basic. One assessment found it especially clean and intuitive, while others wanted much more depth.

Cohesion was praised, with reviewers describing the presentation as unified, whole, and remarkably cohesive.

Most material sounds open, organized, and easy to follow, with clear separation between instruments. Midrange mismatch can weaken cohesion, and one strongly negative test found the presentation entirely unconvincing.

The microphone system was tied to clearer, more transparent voice calls in review evidence.

The built-in microphone performed better than expected in a real call, keeping voices clear and background noise controlled. The caller barely noticed the speakerphone was being used.

Reviewers generally found the small speaker louder than expected for its size, but several cautioned that it is not built to fill bigger rooms or outmuscle larger rivals.

Output is ample for desks, bedrooms, and smaller gatherings, and one test found it could fill a living room. It is not a party speaker, though, and the harshest test found maximum volume dramatically limited.

High-volume behavior was praised for staying controlled, with reviewers reporting little distortion even when the speaker was pushed.

Most tests found the Muo clean and composed at high volume, with little obvious distortion until the extremes. One highly critical test instead heard severe clipping and bass breakup, making this a sharply divided area.

The tonal balance was widely praised for rich, controlled bass, clear mids, and refined highs, with a few caveats around ultimate bass depth and one first-impression review finding it flat.

The dominant impression is balanced, natural tuning with clear separation and restrained bass emphasis. Some tests heard shouty or recessed mids, and one strongly negative assessment called the sound boxy and hollow.

The leather strap drew praise as expertly crafted and part of the speaker’s premium look.

The removable color-matched strap is sturdy, discreet, and useful around the house or outdoors. Even skeptical commentary still regarded it as a practical addition.

Price opinion was split: many reviewers saw the speaker as expensive, but several argued its build, sound, and longevity justified the premium.

The Muo's premium materials, refined sound, and connectivity justify the price for design-conscious music lovers. Buyers prioritizing maximum loudness, bass, or features per dollar will find cheaper rivals more compelling.

Portability was strong overall: reviewers liked the bag-friendly size and balanced heft, though it is not the lightest compact speaker.

At roughly 740 grams, the Muo is compact enough for bags and travel while still feeling substantial. Its dense build is slightly heavier than some rivals and less comfortable for all-day hand carrying.

Vocal reproduction was a consistent strength, with reviewers praising intelligibility, definition, and natural-sounding voices in music.

Voices are usually clear, textured, and unusually natural for a compact speaker, especially at moderate levels. A few listeners found the midrange too forward, strident, or slightly recessed depending on material.

Durability was mixed: reviewers liked the tough build and survival in bags, but several warned the metal finish can scuff and the speaker should not be thrown around like rugged JBL models.

The structure feels robust enough for normal outdoor use, but the smooth aluminum finish is easy to mark, scratch, or dent. It can survive weather better than careless packing.

Detail retrieval was a major strength across reviews, with repeated praise for high detail, clarity, and track-level separation.

Fine texture, instrument separation, and small recording details are recurring strengths. The Muo often sounds more open and articulate than typical compact Bluetooth speakers.

USB-C wired audio was praised as a meaningful bonus, especially because reviewers heard clearer, punchier performance through a cable.

USB-C audio is widely treated as a useful advantage for computers, phones, and low-latency desk use. One listener heard little sonic improvement over Bluetooth, but still recognized it as a meaningful upgrade.

Construction quality was repeatedly praised for premium materials, flawless finishing, and a substantial feel.

Machined aluminum, solid end caps, and premium finishing give the Muo excellent perceived build quality. The tradeoff is a surface that can collect scratches and dents more easily than rugged rubber designs.

Battery life was a consistent strength, with reviewers calling the 24-hour figure credible, impressive, and in some tests conservative.

Battery life is a major strength: one measured test reached 22 hours 38 minutes, while a louder test still managed 11 hours 39 minutes. A skeptical assessment questioned the unspecified conditions behind the 24-hour claim.

Everyday usability was praised for simple operation and controls that were easy to use without friction.

Orientation sensing, portable dimensions, weather protection, USB-C audio, and simple daily controls make the Muo highly versatile. It works especially well across desks, kitchens, patios, offices, and travel.

Codec support was considered solid, with aptX Adaptive repeatedly framed as a welcome or high-quality advantage.

Bluetooth 5.4 with AAC, SBC, and aptX Adaptive gives the Muo strong modern codec coverage. aptX benefits depend on a compatible source, and one listener found the real-world improvement modest.

Connection stability was consistently positive, with reviewers reporting no pairing or dropout issues in normal testing.

Pairing connects quickly and remains stable, including in environments where interference could be a concern. Reconnection to the most recent device is also dependable.

Imaging and spatial organization were praised for openness and instrument separation, though one review noted limited scale compared with larger rivals.

A single Muo throws a wider stage than its size suggests, while two units noticeably sharpen left-right placement and immersion. The mono presentation still cannot match a true stereo setup on its own.

Design and aesthetics were one of the strongest consensus points, with nearly every reviewer praising the premium, elegant, luxurious look and feel.

The curved aluminum body, seven finishes, and compact form consistently look and feel premium. Some find the nearly unchanged design dated, but it still stands apart from ordinary rubberized speakers.

Speakerphone performance was praised, with reviewers describing calls as clear, successful, and even a ten-out-of-ten hands-free experience.

Calls are clear and practical in quiet to moderately noisy spaces, with useful echo and noise control. It is suitable for meetings and quick conversations but not a replacement for a dedicated conference microphone.

Inter-speaker connectivity was praised where tested, especially for quick stereo setup and pairing with another A1.

Two Muos can create true stereo, while Auracast expands playback to multiple compatible speakers. The feature is compelling for offices, bedrooms, and parties, though buying several units becomes expensive.

Dynamic headroom was good but not class-leading: some reviews praised dynamism, while others wanted stronger quiet-to-loud swings.

Most testing found the speaker able to move from quiet to loud without stress and preserve dynamic contrast. One severe dissenting test heard aggressive limiting that pushed output down.

Setup was described as quick and issue-free in one review’s pairing experience.

Basic Bluetooth pairing is quick and easy, especially with Fast Pair and Swift Pair. Stereo and USB-C modes can require less obvious button combinations.

Sustainability stood out through repairability, replaceable battery comments, and praise for longevity-focused design.

Recycled plastics from bottles and electronic waste give the Muo a more thoughtful sustainability story than many premium portables. The material choice complements rather than cheapens the design.

Water resistance was strongly supported by outdoor-use praise and hands-on dunk or sink tests that reported no damage.

IP67 protection makes the Muo comfortable around rain, kitchens, beaches, and accidental splashes or brief immersion. Multiple hands-on accounts found it reassuringly robust outdoors.

One reviewer tested pairing across generations and found the stereo-pairing experience impressive and reliable.

True Wireless Stereo pairing stayed stable during extended testing. Once connected, two speakers maintained a dependable left-right setup.

USB-C charging was praised when paired with simultaneous laptop playback, making the port more useful than simple charging.

USB-C fast charging keeps the Muo current and convenient. The same port also supports audio, making one cable useful for both power and playback.

AirPlay compatibility was a clear omission in the Macworld review, which said the lack of Wi-Fi or AirPlay kept it from being perfect for Apple users.

USB-C playback supports high-resolution digital audio and turns the Muo into a strong compact desk speaker. It is a useful alternative to lossy Bluetooth.

Backwards compatibility was a clear plus because multiple reviewers valued pairing the 3rd Gen with the older A1 2nd Gen.

Bass opinions vary more than any other trait: many heard deep, tight, textured impact, while others found sub-bass soft or heavily reduced as volume rose. One test reported severe distortion and disputed the claimed extension.

Bluetooth range was workable but not exceptional, with one review keeping it near the same room and another noting dropouts only near the end of a garden test.

Podcasts and spoken content came through clearly even with surrounding noise. The dialogue-focused DSP setting can push voices forward for easier listening.

The IP67 enclosure is consistently praised for dependable dust protection in travel and outdoor use. It meaningfully broadens where this premium-looking speaker can be used.

Despite IP67 water protection, the Muo does not float. That makes pool or deep-water use less reassuring than with floating outdoor speakers.

Google Fast Pair makes Android connection quick and nearly effortless. It is one of the Muo's more practical convenience features.

Video sync is generally tight over Bluetooth, with imperceptible or near-imperceptible delay for streaming. Fast-paced gaming can reveal a little lag, while USB-C removes it.

Low-volume listening is a standout strength, staying clear, composed, and full enough for late-night use. Bass support is strongest at quieter settings before DSP reduces it as volume rises.

Multipoint was positively received, especially in hands-on switching tests where it worked easily and flawlessly.

Most listening tests praise the Muo's clarity, balance, spaciousness, and refined hi-fi character across many genres. A minority found it genre-dependent, and one severe outlier judged it distorted and unpleasant.

The broad consensus is positive, centered on premium design, clear sound, long battery life, and versatile connectivity. Satisfaction falls when judged mainly on party output, deep bass, ruggedness, or strict value.

The USB-C port cannot charge a phone or other device. One comparison treated the missing power-bank function as a meaningful practical disadvantage.

The premium aluminum finish feels exposed without a case. Two assessments said a travel cover should have been included, even though the omission was not a deal-breaker.

App-based power, volume, and input control add genuine convenience from across a room. Remote operation is simple even though the app itself is limited.

The Muo is especially well matched to desks, kitchens, bedrooms, offices, and hotel rooms. It stays clear at low volume and can fill intimate spaces without needing party-level output.

Alexa and voice-assistant support were mixed-to-negative: some reviewers did not miss it, while others treated its removal as a lost useful feature.

Status indicators worked but drew mild criticism for size and viewing angle.

Value-for-money sentiment was more divided than price alone, ranging from strong praise in one A1 review to doubts from What Hi-Fi and Expert Reviews at the current price.

Wi-Fi streaming was a drawback for Apple-focused users because the speaker lacks Wi-Fi and AirPlay support.
