Audio-Technica ATH-M40x Professional Monitor Headphones

Studio monitoring headphones

The Audio-Technica ATH-M40x professional monitor headphones are tuned flat for accurate audio monitoring across an extended frequency range. They suit studio engineers, producers and DJs who need reliable reference sound for tracking and mixing. The circumaural design contours around the ears to provide excellent sound isolation in loud environments. 90 swiveling earcups allow convenient one-ear monitoring during sessions.

Passive thermal and acoustic design

These wired headphones require no power supply, so they generate no heat and draw no electrical power during use. The closed-back circumaural earcups provide passive noise isolation by physically sealing around the ears. This acoustic seal keeps external sound out and prevents audio bleed into open microphones. No active cooling or noise-cancelling circuitry is present to affect the signal path.

Consistent performance under extended sessions

The 40 mm drivers with rare earth magnets and copper-clad aluminum wire voice coils maintain their flat tuning during long tracking or mixing periods. Because the design is completely passive, there is no battery to deplete, no firmware to throttle and no thermal limit that alters the frequency response. Robust construction and pro-grade materials ensure the headphones withstand daily professional use without degradation.
