Pros
Balanced, natural and highly detailed sound with excellent dynamic expression and controlled frequency integration.
USB-DAC mode delivers notably sharper separation, fine detail and hi-res playback up to 24-bit/192kHz.
Premium, durable construction with soft leather and memory-foam pads supports comfortable long listening sessions.
Cons
Bass can sound thick or occasionally muddy without EQ on some material.
Noise cancellation is effective but falls short of the very best Bose and Sony implementations.
At 350g, the design is relatively heavy; some listeners may also find their ears get warm during use.

What Reviewers Are Saying
SOUND QUALITY PERFORMANCE 90/100
Reviewers find the Bathys MG unusually refined and resolving for a wireless noise-cancelling headphone, with a warm, rich balance, convincing punch and notably strong clarity in USB-DAC mode. Its principal sonic caveat is an elevated low end that can sound thick or occasionally muddy without EQ, while the treble may bring a touch of sharpness on some material.
Bass
87/100
Bass reaches deeply and is widely praised for impact, weight and improved control over the original Bathys. However, several reviewers hear considerable resonance or thickness, with MajorHifi finding it occasionally muddy and The Headphone Show preferring a tighter, more tactile low end; the app EQ can help.
Midrange
92/100
The midrange earns especially enthusiastic feedback for its rich body, clarity and expressive instrumental tone. The Headphone Show calls it a meaningful advance over the original on piano, acoustic instruments and vocals, though MajorHifi found some vocals slightly veiled relative to the otherwise clear mids.
Treble
89/100
Reviewers describe the treble as clear, refined and capable of drawing out crisp shimmer and ambient detail without persistent sibilance. There is some caution around a mid-treble edge: The Headphone Show notes sharpness around sibilants, even as other reviewers praise the smooth, controlled presentation.
Resolution Detail
92/100
Detail retrieval is a major strength, with What Hi-Fi praising layers of texture and insight beyond cheaper flagship wireless rivals. USB-DAC mode receives particular acclaim for sharper separation and fine detail, although MajorHifi felt bass definition could obscure articulation on some tracks.
Soundstage Imaging
87/100
The presentation has precise placement, strong separation and useful depth, allowing instruments and vocals to remain clearly located. It is not an especially expansive stage, even by closed-back standards according to Audioholics, but the stable imaging and layering make the space convincing.
Dynamics
92/100
The Bathys MG is repeatedly described as punchy, impactful and dynamically assured, with drum hits carrying weight, texture and clear gradation. Reviewers also note that it retains composure at higher levels, while DAC mode further improves transient definition and nuance.
Assessments of Build Quality, Usability, and Overall Propositions.
Comfort Fit
89/100
The softer leather-and-memory-foam pads and improved clamp distribution are consistently praised, with multiple reviewers reporting comfortable hours-long sessions and no meaningful pressure points. Heat can build up for some listeners, and people with large ears may feel the back of the pad or baffle, but these are limited caveats.
Build Quality
92/100
Reviewers consistently regard the Bathys MG as a premium, sturdily made headphone, highlighting the leather headband, magnesium yokes, aluminium accents and high-quality pads. MajorHifi and Audioholics specifically describe it as built to last, while the finish and materials reinforce its luxury positioning.
Features Usability
91/100
This is a versatile wireless headphone with multipoint Bluetooth, app-based EQ and personalization, effective ANC, a carrying case, analogue connection and a high-resolution USB-DAC mode. ANC is repeatedly described as very good rather than class-leading, and one reviewer encountered possible multipoint bugs, but the overall feature set is exceptionally capable for travel, work and focused listening.
Value for Money
86/100
At $1,499, the Bathys MG is an expensive proposition, and The Headphone Show questions whether its improvement over the original fully warrants the price increase. On the other hand, Audioholics calls it a relative bargain among high-end portable closed-backs, while other reviewers consider it a credible best-in-class alternative for buyers prioritising sound quality alongside wireless convenience.
