What it is
The ATH-M50xBT2 is a pair of closed-back wireless over-ear headphones from Audio-Technica, announced and put on sale on 18 August 2021 (Audio-Technica press release). It replaced the ATH-M50xBT as the wireless version of the ATH-M50x studio monitor headphones, and keeps that model's 45 mm drivers, ear pads, headband and fold-flat design with 90-degree swivelling ear cups (Audio-Technica product page).
Over Bluetooth 5.0 it supports the SBC, AAC and LDAC codecs, pairs with two devices at once and has a low latency mode. Wireless playback runs through an AK4331 DAC and a dedicated headphone amp. Buttons on the left ear cup handle volume, playback, calls and voice assistants, and two beamforming microphones pick up calls. The free A-T Connect app for iOS and Android sets the EQ, low latency mode, codec, left/right balance and voice assistant; EQ settings apply over Bluetooth only.
Battery life is about 50 hours, a full charge over USB-C takes about 3.5 hours, and a 10-minute charge gives up to 3 hours. The detachable 1.2 m cable with 3.5 mm plugs plays even with a flat battery, though the buttons and microphones don't work when wired. Impedance is 38 ohms, sensitivity 99 dB/mW, and the headphones weigh about 307 g.
The box holds a 30 cm USB-A to USB-C charging cable, the 1.2 m audio cable and a pouch. There is no 6.3 mm (1/4") adapter for a mixer or controller socket.
