Audio-Technica ATH-M40x Closed-Back Monitor Headphones

Closed-Back Studio Headphones for Tracking, Mixing, and DJ Monitoring

The Audio-Technica ATH-M40x Closed-Back Monitor Headphones are designed for studio tracking, mixing, location recording, DJing, and daily listening where accurate sound and reliable isolation are important. Their over-ear closed-back design helps separate the listener from outside noise, making them a practical choice for production rooms, mobile recording setups, editing stations, DJ rigs, and focused personal listening.

Equipped with 40mm dynamic drivers with rare earth neodymium magnets and CCAW voice coils, the ATH-M40x headphones are tuned for a flat, accurate response across a 15 Hz to 24 kHz frequency range. This makes them well suited for monitoring program audio, checking mixes, and hearing detail across a wide spectrum without relying on exaggerated headphone voicing.

The ATH-M40x features 90-degree swiveling earcups for flexible fit and one-ear monitoring, which is useful for DJs, singers, and production users who need to monitor room sound and headphone playback at the same time. Generous cushioning on the headband and earpads supports comfort during longer sessions, while the foldable construction and included carrying pouch make storage and transport easier.

Two detachable single-sided cables are included for different workflow needs: a 3.9 to 9.8 ft coiled cable and a 9.8 ft straight cable. Each cable uses a gold-plated 3.5mm TRS mini plug, and the included quarter-inch screw-on adapter supports connection to compatible audio interfaces, mixers, stereo receivers, and dedicated headphone amplifiers.
