Product Overview
The Audio-Technica ATH-M40x is a pair of closed-back professional studio monitor headphones tuned flat for accurate monitoring across the frequency range. With 40 mm drivers and detachable cables, they suit tracking, mixing, and broadcast monitoring in studios and AV control rooms. The closed-back design provides isolation for critical listening in noisy environments.
Product Description
The ATH-M40x is built for accurate monitoring rather than colored playback, with a flat tuning that supports consistent mixing decisions. Its 40 mm drivers deliver clear detail from a low 15 Hz to an extended 28,000 Hz.

An impedance of 38 ohms and 99 dB sensitivity let the headphones run from interfaces, mixers, and portable devices without a separate amplifier in most cases. The closed-back earcups isolate the listener and reduce bleed into open microphones.
Detachable cables simplify replacement and storage, and the earcups swivel for single-ear monitoring. For a lighter-duty option, the ATH-M30x shares the same 40 mm driver platform.
