Focal Bathys
Open pageThe Bathys is a closed-back wireless ANC over-ear built around a 40mm aluminium-magnesium M-shaped dome driver, and it is judged first on sound. The tuning follows a Harman-leaning philosophy: smooth and fairly dense, with a clean midrange called a standout in its class, vocals forward without shouting, and a top end that relaxes from about 4kHz so sparkle is limited while sibilance is effectively absent. Bass is where accounts split, between a lifted shelf peaking around 50Hz that reads as powerful and punchy, and a low end described as subdued, or as deep sub-bass rumble that reserves itself rather than dominating. Staging divides the same way, from among the best heard on a Bluetooth over-ear to a rounded, intimate space whose distance portrayal leaves something to be desired. Running the headphone over USB-DAC instead of Bluetooth tightens the low end, adds treble bite and enlarges the stage. Build draws less argument: magnesium yokes, an aluminium headband, leather and memory foam pads, 350g, and no creak in the articulation. Noise cancelling is strong below roughly 1-2kHz and lets more midrange and voice through, and it is placed behind the Sony, Bose and Apple flagships, with low-frequency attenuation measured close to 20dB. There is no LDAC and no passive mode, so a flat battery means silence. Price is the standing objection: it launched at $799, and one verdict is that less expensive alternatives cover most of the same ground.
Strengths
- Sound quality is the headline: an accurate frequency balance that earns the best-sounding-ANC-headphone label in this category.
- Midrange is the standout band, cleanly separated from the bass and tonally transparent, with a 3kHz hump balancing male and female vocals.
- Premium build for the class: magnesium yokes, an aluminium headband, leather and memory foam pads, and no creak in the articulation.
- USB-DAC mode is a real second gear, tightening the low end, adding treble bite and enlarging the stage well past Bluetooth.
- Battery beat its 30-hour rating in a standardized test, running 31 hours 30 minutes with ANC engaged.
- The top end sidesteps the 6kHz and 8kHz sharpness zones, so long sessions stay clean with effectively no sibilance.
Weaknesses
- Noise cancelling sits behind the Sony, Bose and Apple flagships, with low-frequency attenuation measured close to 20dB.
- Cancellation weakens above roughly 1-2kHz, letting more midrange and human voice through than rival flagships do.
- Treble relaxes from about 4kHz, so air and sparkle are limited and percussion bite and crunch are reduced.
- Stage depth is intimate over Bluetooth and distance portrayal is weak, a limit of the closed-back ANC design.
- No LDAC, and no passive mode: once the battery is flat the headphone stops working entirely.
- The thin headband can cause soreness at the crown after a few hours, and 350g can be a problem for slighter listeners.
