Compare Focal Bathys MG Wireless Headphones vs Sonos Ace Wireless Over-Ear Headphones

ANC is good to very good and clearly improved over the original, but the consensus is that Sony and Bose still cancel more noise overall, especially in the mids. The three-mode ANC system gives useful control with Silent, Soft, and Transparency options, even though there is no true ANC-off mode.

ANC is widely rated strong for travel and commuting, and multiple reviewers say firmware updates pushed it closer to class leaders. A minority still place Bose and Sony slightly ahead, but few call the Ace weak at cancelling steady noise. Most reviews describe limited user control over ANC intensity: typically on, off, or Aware mode, with some adaptive behavior added over time. If you want multiple manual levels like Bose offers, this is a common disappointment.

Android support is straightforward, with repeated references to Android compatibility in specs, pairing, and app support.

Android compatibility is generally solid, and Android users get the biggest upside from aptX Lossless and broader codec support. Some Sonos home-theater features started iOS-first, but later updates expanded support according to reviewers.

The Focal & Naim app is useful for basics like ANC, EQ, personalization, lighting, and battery view, but several reviewers find it limited or occasionally glitchy.

The Sonos app is needed for setup, updates, EQ, and home-theater features, and opinions are mixed. Some like the simplicity and redesign, while others report pairing hiccups, limited options, or updates that feel slower than they should.

aptX support is a clear plus and is repeatedly listed as part of the headphone's strong everyday wireless feature set.

aptX support, including aptX Lossless on compatible Snapdragon Sound devices, is frequently cited as a meaningful advantage over some rivals. Android users benefit most from this capability.

Audio-video sync is usually described as low-latency for movies and TV, especially when features are working properly. A couple of reviews report occasional lip-sync hiccups during TV Audio Swap that were resolved by reconnecting or pausing playback.

Bass is generally praised for depth, slam, texture, and control, though several reviewers note the default tuning can run a little warm, boomy, or heavy before EQ.

Bass is commonly described as full and controlled, helping the Ace feel rich and premium. Some reviewers want more rumble and impact for movies, while others feel the default tuning can lean a bit bass-forward compared with neutral targets.

Battery life is solid rather than class-leading, with the commonly cited 30-hour Bluetooth figure generally holding up well in real use. Battery replacement appears possible through Focal service rather than as a user-swappable design, offering some serviceability without true end-user replaceability.

Battery life is generally reported around the advertised 30 hours with ANC, and several reviewers call it a strong point. A few wish it were longer, but most agree it is competitive in the premium class.

Bluetooth performance is usually stable with fast pairing and dependable everyday use, but a few reports mention quirks rather than flawless behavior.

Bluetooth stability is mostly reported as solid with reliable day-to-day connections. Some reviews mention brief dropouts or stutters, especially around early firmware or when using TV Audio Swap.

Build quality is one of the strongest consensus positives, with premium materials, excellent finishing, and solid construction throughout.

Build quality is typically described as premium and well-finished, with sturdy materials and a polished look. A few reviews mention early quirks or software-related rough edges, but physical construction is rarely the main complaint.

The built-in DAC and hi-res USB playback are among the headphone's clearest differentiators, and many reviewers treat DAC mode as a headline feature.

Physical controls are a strength, with tactile buttons and switches that are generally easier to trust than touch panels.

The included cables are generally described as acceptable to durable, even if they are not luxurious extras.

Cable quality is mostly fine, but at least one review explicitly complains that the included USB-C cable is too short for comfortable desktop or couch use.

The carry case is repeatedly praised as protective, slim, and premium, even if a few users still find it bulky in a bag.

The included case is usually praised as protective and slim, and it looks premium on the outside. A few reviewers dislike the material feel, zipper behavior, or the finicky fit when packing the headphones away.

Fast charging is a practical plus, with the widely repeated 15-minute top-up for roughly five hours of playback.

USB-C charging and fast-charge behavior are widely praised, with multiple reviews citing short top-ups that deliver hours of use. Full charge times and convenience compare well against Lightning-based rivals.

Clamp is generally better judged than on the original Bathys, feeling secure without being overly oppressive for most listeners.

Codec support is serviceable rather than cutting-edge: aptX and aptX Adaptive are welcome, but multiple reviews call out the lack of broader premium codec coverage.

Codec support is a key talking point: AAC for iPhone, aptX and aptX Lossless via Snapdragon Sound for compatible Android, plus wired USB-C audio. One review notes the lack of LDAC, so codec completeness depends on what you expect.

Long-session comfort is one of the Bathys MG's most consistent wins, with many reviewers praising fatigue-free wear over flights, workdays, or extended listening.

Comfort is one of the strongest consensus positives: many reviewers say the Ace disappears on the head for long sessions. Some note the cups can feel tight for larger ears or get warm, but comfort is still often ranked top tier.

Design is a major selling point, with the chestnut finish, leather, metal accents, and illuminated logo giving the Bathys MG a clearly luxurious identity.

Design is broadly seen as sleek, minimalist, and premium, with physical controls that many find more reliable than touch pads. Cosmetic preferences vary, but the Ace generally scores high on aesthetics.

The included 3.5mm and USB-C wired options add real convenience for travel, desk use, and higher-quality listening beyond Bluetooth.

Softer, more supple pads are a meaningful upgrade, improving comfort, seal, and overall premium feel.

The cups offer enough articulation to sit comfortably and fold flat, but the headphone is not especially compact and does not fold into a tighter travel shape.

EQ is helpful and usable, but the five-band structure is repeatedly described as limited compared with fuller parametric options.

EQ customization is frequently described as basic, often limited to simple bass and treble adjustments. It helps fine-tune warmth but is less flexible than multi-band EQs offered by several competitors.

Reviewers consistently describe the tonal balance as natural, balanced, or close to reference in the better presets, with cleaner frequency relationships than the original Bathys.

The headband and slider system is easy to adjust and feels premium, helping users dial in fit without fuss.

The yokes and hinge-related hardware are widely described as sturdy, well finished, and built to last.

The included bundle is straightforward but useful, typically covering the hard case plus 3.5mm and USB-C cables.

Included accessories, especially the hard case and cables or adapters, are generally viewed as generous for the category. A couple of reviewers still wish for longer cables or more flexibility, but the bundle is mostly well received.

Instrument separation is frequently singled out as excellent, with strong channel separation, precise placement, and the ability to keep dense mixes organized.

Instrument separation and imaging are often highlighted as a strength, with good layering and placement for a wireless ANC headphone. Even mixed reviews tend to credit the Ace for clarity in complex mixes.

The built-in mic setup is a practical part of the package, handling calls, assistants, and ANC duties without standing out as a weak point.

LDAC is a notable omission and one of the most commonly cited feature complaints at this price.

At louder playback levels the Bathys MG generally stays composed and detailed, but some reviewers still hear treble edge on bright material, so max-volume behavior is good rather than perfect.

The microphone array does a respectable job suppressing background noise and keeping speech intelligible, though wind and harsher noise are not fully erased.

Microphone noise reduction is often described as effective at suppressing background noise, though not always the best in class for wind or the noisiest streets. Overall, most reviewers consider it reliable for calls.

Call quality is generally solid, with voices coming through clearly and naturally even if the very best Sony-style call performance is still a step ahead.

Call quality is generally rated good to very good, with clear speech in typical environments. A few reviews call it average or slightly muffled, and one notes updates aimed at improving the microphones over time.

Midrange performance is a major strength, delivering clear, rich, weighty instruments and improved vocal/instrument resolution over the original, even if a few reviewers wanted vocals pushed further forward.

Midrange is typically clear and pleasant for vocals, though a few reviews note mild recession depending on the track and default tuning. With light EQ, several reviewers say vocals regain balance easily.

The Bathys MG works broadly across phones, computers, tablets, and wired sources, making it easy to use across mixed-device setups.

Multi-platform compatibility is generally strong for phones and computers, and the Ace can also integrate with compatible Sonos soundbars. The biggest platform caveats are codec differences (Android vs iOS) and which devices support specific Sonos features.

Multipoint is supported and often works well, though several reviewers mention occasional switching quirks that keep it from feeling completely polished.

Multipoint is commonly praised for convenience and generally works well for hopping between phone and laptop. One review reports clunky or inconsistent behavior, so it is not universally flawless.

Passive isolation benefits from the over-ear seal and softer pads, though seal sensitivity with glasses is noted by at least one reviewer and total isolation still leans on ANC.

Portability is decent for a premium over-ear: the headphone folds flat and the revised case is slimmer, but it still is not a truly compact travel design.

The Ace folds flat but does not fold into a compact bundle, so portability depends heavily on bag space. The case is often described as slim, but still fairly wide.

Preset profiles, especially Dynamic, are viewed positively and can materially improve tonal balance depending on listener taste.

Replaceable earpads are explicitly mentioned and add welcome long-term serviceability.

Replaceable, often magnetically attached earpads are praised as a practical, premium touch for long-term ownership. Reviewers generally like the ease of removing and reattaching pads.

Convenience sensors are sparse, with at least one reviewer specifically calling out the lack of wear detection.

Sidetone adjustment is present in the app, but it is not explored deeply enough in reviews to suggest anything beyond basic usefulness.

Sidetone is highlighted as a useful calling feature when available, feeding some of your own voice back naturally so you do not over-project. Not every review treats it as essential, but those who mention it tend to be positive.

Setup is usually straightforward, but the app and feature set are not always as polished or flexible as the best consumer-audio ecosystems.

Setup and software are mixed: many find pairing straightforward, while others report app detection issues, feature rollouts that arrive later, or firmware updates that take patience. Updates have also meaningfully improved ANC and home-theater features over time.

Across the file, the Bathys MG is repeatedly described as one of the best-sounding wireless headphones available, with standout refinement, detail, dynamics, and realism. Wired listening is a real strength, especially in USB-DAC mode, with reviewers repeatedly hearing cleaner, higher-resolution playback than over standard Bluetooth.

Sound quality is generally praised as warm, smooth, detailed, and spacious, making it easy to enjoy for long sessions. The recurring critique is that it is not always as punchy, dynamic, or incisive as the very best at this price, and the limited EQ means you cannot fully reshape the signature.

For a closed-back wireless design, the Bathys MG earns unusually strong soundstage marks, with convincing width, layering, and better spatial openness than most ANC rivals.

Soundstage is frequently called spacious for a closed-back, and it becomes more enveloping with spatial audio enabled. Reviews describing movie playback often emphasize the wide, out-of-head presentation.

Spatial audio is absent, and several reviewers explicitly note that Focal prioritized core sound over that feature.

Spatial audio and Dolby Atmos support are widely considered a headline strength, especially for movies and TV, with head tracking adding immersion for many listeners. A minority see it as a gimmick for music, but overall sentiment is strongly positive.

Fit stability is mostly good for seated use and commuting, but a few comments suggest movement-related thumping or shifting during more active use.

Stability on the head is usually good for everyday use, but one review notes slipping when sweaty. If you plan on workouts, fit stability and heat build-up can be a consideration.

The packaging and material story show some environmental consideration, including recycled or FSC-style materials in the box and presentation.

There are no touch controls here, so anyone wanting swipe gestures or tap controls will not find them.

Transparency mode is considered effective and natural enough for conversations and situational awareness without removing the headphones.

Transparency or Aware mode is consistently described as natural and easy for conversations, often compared favorably with top competitors. A few reviewers still prefer Apple or Bose, but overall sentiment is very positive.

Treble is mostly clear, smooth, and detailed, but a few reviewers hear some edge or heat up top, especially on bright recordings or at louder levels.

Treble is usually characterized as clean and non-fatiguing, avoiding harshness. A few listeners want more sparkle and air, especially compared with brighter, more energetic rivals.

USB-C is central to the product experience, handling charging and the high-value DAC mode for higher-resolution wired playback.

USB-C is consistently appreciated for both charging and wired audio, and many reviews call it a clear win over older Lightning implementations. It also supports practical desktop and travel use cases.

Voice assistant access is built in and works as expected through the dedicated button and supported platforms.

Most reviewers find music playback loud enough, but TV Audio Swap volume is repeatedly described as quieter than music. At least one reviewer also reports a low-volume floor or coarse steps that make quiet listening harder.

Multiple reviews point out there is no official IP rating, making the Ace a weaker pick for workouts, heavy sweat, or rain exposure. Some still use it casually at the gym, but it is not positioned as a sport headphone.

At about 350g the Bathys MG is not especially light, but most reviewers still find the weight well managed and comfortable in practice.

Weight comfort is routinely praised, especially compared with heavier metal competitors. The lighter feel is a major contributor to long-session wearability.
