Compare Focal Bathys MG Wireless Headphones vs Bose QuietComfort Ultra Wireless 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 consistently described as class-leading, excelling on planes, trains, and busy streets; a few note rare odd behavior with extremely loud peaks. Noise canceling is highly adjustable through modes and a 10-step slider, often with wind control, but several reviewers dislike the lack of a true ANC-off state.

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

Android works well for basics, but best codec features depend on compatible Snapdragon hardware and may fall back to AAC on some popular phones.

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 Bose Music app is easy to navigate for modes, updates, and basic customization, but power users may find it simpler than competing apps.

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

aptX Adaptive/Lossless is a notable perk for supported phones, but real-world availability varies and some reviews warn of inconsistent handset support.

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 strong and punchy; fans call it controlled and fun, while detractors describe it as too heavy or less controlled without EQ.

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 typically described as mid-pack (around 24 hours), with Immersive Audio often cutting it to roughly 18 hours; some find it acceptable, others call it a weakness.

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

Bluetooth connection is generally stable with good range, with occasional reports of finickiness on some computers.

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

Build is seen as solid but not the most premium; a few report rattles or long-term wear concerns, while others find it durable enough for daily travel.

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.

Controls mix physical buttons with a touch strip; many like the simple layout, but some dislike multi-press functions and loud button clicks.

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

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

The hard, zippered carrying case is frequently praised as compact and protective, usually including storage for cables and accessories.

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

Charging performance is strong, with fast-charge claims commonly cited and the ability to top up quickly for a few hours of listening.

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

Clamping force is usually described as gentle and well-judged; the comfort-focused clamp can reduce stability for vigorous movement.

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 centers on SBC/AAC plus Snapdragon Sound with aptX Adaptive/Lossless on compatible devices; Bluetooth 5.3 and LE Audio readiness are mentioned, though rollout varies.

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.

Long-wear comfort is a standout: lightweight feel, soft cushioning, and glasses-friendly fit make it easy to wear for hours.

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 understated and modern with premium touches, but several reviewers call it low-key and wish it stood out more.

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.

Ear pads are widely praised as plush, but some long-term use reports mention compression/divots and concerns about thin pleather longevity.

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 is available but limited (often described as a 3-band slider with modest sensitivity), so deep tuning is not a strength.

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.

Headband adjustment is smooth and fits a wide range of head sizes, helping distribute pressure for comfort.

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

The dual-hinge folding design improves packability; most find it sturdy, though pinch points and occasional rattles are mentioned.

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

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

Separation and imaging are strong, but a few sources mention channel matching or processing can affect spatial cues.

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.

Clarity generally holds up at higher volumes, with multiple reviewers noting strong detail retention when turned up.

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

Noise reduction for calls is often effective in busy environments, but some tests still capture background announcements or office noise.

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 reviews are mixed: some describe it as excellent with clear voice pickup, while others report graininess, robotic tone, or dropouts in meetings.

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 generally clear and present, though some note it can sit behind the bass depending on track and tuning.

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

Cross-platform use is strong overall, working well with iOS, Android, and computers for everyday listening.

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

Multipoint is supported and usually reliable, enabling easy switching between phone and laptop; switching behavior can be manual depending on use.

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.

Large, plush pads create a strong seal that boosts passive isolation and supports the overall noise-reduction performance.

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.

Fold-up-and-flat portability is a key advantage, helping the headphones and case take up less space than some rivals.

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

Preset EQ profiles exist (for example bass/treble focused presets), but the selection and granularity are limited compared with rivals.

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

Earpads are removable/replaceable according to at least one review, which is a plus for long-term maintenance, though long-term pad wear and compression are still discussed.

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

Sensors enable wear detection, auto-pause/resume, and sleep/auto-off behavior that helps conserve battery, though detection can feel slow for some.

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

The black finish can show fingerprints and smudges more than lighter colorways.

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

Setup is generally straightforward with fast pairing on supported devices; a few note slower on-head detection or reconnection in daily use.

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.

Overall sound is widely described as rich, detailed, and engaging with a bass-forward tilt; some reviewers still prefer more neutral or more detailed rivals.

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 above average for closed-back ANC headphones, and Immersive Audio can widen it further with varying success.

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

Immersive/spatial audio can widen the presentation for some content, but many find it inconsistent or overly processed and note the battery hit.

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 excellent for desk and travel use, but some reviewers report slipping/falling during dynamic workouts or bending.

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.

The touch volume strip/slider is often described as responsive and easy by feel, though some users report accidental volume jumps.

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

Transparency/Aware mode is repeatedly praised as natural and low-hiss, close to AirPods Max quality and especially useful for office awareness.

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 typically detailed and crisp without harshness, though a few describe it as slightly distant or affected by processing.

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

USB-C is charging-only; lack of USB-C digital audio passthrough is a repeated complaint for a flagship-priced model.

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

Voice assistant access is typically supported via a customizable shortcut, making hands-free control convenient for many users.

Maximum volume output is described as very loud with ample headroom.

There is no IP rating, and multiple reviews advise against heavy sweat or rain exposure despite the headphones handling normal daily use.

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

Weight is generally considered light for the class (around 250g), contributing to reduced fatigue over long sessions.
