Focal’s wireless noise-cancelling headphone, with a real USB-DAC mode at 24-bit / 192kHz and drivers made in its own French workshops. Bathys arrived in 2022 as Focal’s first wireless noise-cancelling headphone and remains the entry point into the company’s Bluetooth range. It sits below the Bathys MG rather than having been replaced by it; Focal sells both. The driver is a 40mm aluminium/magnesium ‘M’-shaped dome made in Focal’s workshops in France, the same inverted-dome geometry the company uses across its wired headphones. What separates it from most travel headphones is the USB-DAC mode: connect over USB-C and the Bluetooth chain is bypassed entirely, up to 24-bit / 192kHz. Over the air it runs Bluetooth 5.1 with SBC, AAC, aptX and aptX Adaptive. Noise cancelling runs in three modes. Silent gives maximum attenuation for an aircraft cabin; Soft reduces the lowest frequencies while leaving you aware of the room, which suits an office; Transparent passes ambient sound so you can hold a conversation without taking the headphones off. Eight microphones handle the cancelling, two of them dedicated to calls under Focal’s Clear Voice Capture. The Focal & Naim app adds a five-band equaliser with saveable presets, the Mimi hearing test, control of the earcup light, firmware updates and voice assistant selection. One thing worth knowing before you buy: both the 3.5mm jack and the USB input are actively amplified, so the headphones will not play at all with a flat battery. That is also why the wired figures are higher than the wireless one — 35 hours on the jack and 42 in USB-DAC mode, against 30 hours over Bluetooth with cancelling running, because the radio is switched off rather than because the headphone has gone passive.
