Наушники — Audio-Technica ATH-M20xBT

The ATH-M20xBT is the Bluetooth version of Audio-Technica's ATH-M20x, the entry model of the Japanese company's M-Series professional studio headphones. It keeps the tuning and 40mm drivers of the wired M20x but adds a wireless connection, multipoint pairing, a low-latency mode and a long-running battery, while still allowing wired use with the supplied cable. It is designed for listeners who want a monitor-style headphone for commuting, video editing, remote work and home listening.

Key specs that matter

The ATH-M20xBT is a closed-back dynamic headphone with 40mm drivers using rare-earth magnets and copper-clad aluminium wire voice coils. Frequency response is 5Hz to 32kHz, sensitivity is 100dB/mW and impedance is 36 ohms. Bluetooth 5.0 supports the A2DP, AVRCP, HFP and HSP profiles with AAC and SBC codecs and SCMS-T content protection, and multipoint pairing connects to two devices at once. The battery gives up to 60 hours of continuous use, a 10-minute rapid charge gives around three hours, and charging is by USB-C. A microphone and buttons are built into the left earcup. A 1.2m cable with a gold-plated 3.5mm plug and a 30cm USB charging cable are included. The headphone weighs about 216g.

Engineering and use context

Copper-clad aluminium voice coils combine aluminium's low mass with copper's conductivity, keeping the moving parts light, while rare-earth magnets provide a strong magnetic field from a compact motor. The closed-back, over-ear design seals the earcups around the ears, which isolates the listener from surrounding noise and contains spill toward neighbours, useful in open offices and on public transport. With multipoint, it holds links with, for example, a laptop and a phone simultaneously, switching between them as calls or audio arrive. The low-latency mode shortens the Bluetooth transmission delay, improving synchronisation between picture and sound for video and gaming. When connected with the cable, the headphone works as a passive wired model, so it can still be used with an audio interface or mixer or when the battery is flat, which matters for studio use where Bluetooth delay is unacceptable. The earpad and headband materials are taken from Audio-Technica's professional range for durability and long-wear comfort.

Pairing

Wirelessly, the ATH-M20xBT connects to phones, tablets and computers, with AAC suiting Apple devices. Wired, its moderate impedance and good sensitivity make it easy to drive from laptops, audio interfaces and portable players.

Alternatives

Audio-Technica's own ATH-M50xBT2 is the higher M-Series wireless model with larger 45mm drivers and LDAC support.
