Focal Bathys: wireless noise-cancelling headphones
Closed-back Bluetooth headphones made for travel, with 40 mm M-shaped aluminium-magnesium dome drivers, built by Focal: aluminium stiffens the dome and lowers distortion, magnesium damps it.
Noise cancellation
Active noise cancellation has three modes: Silent, the strongest, for planes and trains; Soft, lighter, for home and office; Transparent, which lets voices through so you can talk with the headphones on.
Connections and use
Besides multipoint Bluetooth 5.1, with two devices connected together, you can listen by cable: from the jack or from the USB-C socket, where the built-in converter accepts files up to 24 bit / 192 kHz. The Focal and Naim app sets the five-band equaliser and the listening profile, which a hearing test of a couple of minutes tailors to the wearer; one button calls up the voice assistant.
