Audio-Technica ATH-M20XBT Wireless Over-Ear Headphones (Black)

Audio-Technica ATH-M20xBT (Black)

The Audio-Technica ATH-M20xBT takes the design of the wired ATH-M20x studio headphone and makes it wireless. It is a closed-back, over-ear Bluetooth headphone with 40 mm drivers tuned for enhanced low-frequency performance, up to 60 hours of battery life, multipoint pairing and a low latency mode — a specification aimed at listeners who move between music, video, calls and work on more than one device during the day. In black, with a weight of about 216 grams, it is built as an everyday headphone rather than a fashion piece.

Key features

• 40 mm drivers with rare earth magnets, tuned for enhanced low-frequency performance
• Up to 60 hours of continuous use on a full charge
• Rapid charge: 10 minutes gives up to 3 hours of use
• Multipoint pairing connects two Bluetooth devices at once
• Low latency mode for streaming and gaming
• Bluetooth 5.0 with AAC and SBC codec support
• Built-in microphone and controls on the left earcup
• 1.2 metre cable included for wired listening

Sound and driver design

The 40 mm drivers use rare earth magnets and copper-clad aluminium wire voice coils, and Audio-Technica tunes them for the same sonic signature as the wired M20x, with emphasis on low-frequency weight. The rated frequency response is 5 to 32,000 Hz, with sensitivity of 100 dB/mW and impedance of 36 ohms. The closed-back, over-ear construction surrounds the ear completely, which provides useful passive isolation in offices, on public transport and in shared rooms, and keeps longer sessions comfortable thanks to professional-grade earpad and headband materials.

Battery and charging

Battery life is the headline figure: up to approximately 60 hours of continuous music playback from the internal 3.7 V lithium polymer battery, so charging becomes a weekly event rather than a daily one. When the battery does run low, a 10-minute rapid charge over USB-C provides up to 3 hours of use. A full charge takes approximately 4 hours. The short USB Type-A to USB-C charging cable is included, and if the battery is empty altogether, the supplied 1.2 metre audio cable with a 3.5 mm plug keeps the headphones working as a wired pair.

Multipoint, low latency and calls

Multipoint pairing keeps the ATH-M20xBT connected to two Bluetooth devices simultaneously — a laptop and a phone, for example — so a call can be answered without re-pairing. The low latency mode reduces the delay between picture and sound when watching video or gaming. Supported Bluetooth profiles are A2DP, AVRCP, HFP and HSP, with a line-of-sight operating range of about 10 metres. The omnidirectional microphone, rated at minus 42 dB sensitivity with a 50 to 20,000 Hz response, sits in the left earcup alongside buttons for calls, music playback and volume.

Everyday use

At roughly 216 grams the ATH-M20xBT is light for a full-size over-ear headphone, which matters over a working day of mixed listening and calls. Controls are physical buttons rather than touch surfaces, so volume and playback can be adjusted without looking. The operating temperature range is 5 to 40 degrees Celsius.

For listeners who want the M-Series sound and fit without a cable, and who value battery life and two-device connection over app features, the ATH-M20xBT is a complete and durable answer.
