Engaged Listening
In the studio or onstage, at home or out and about, the closed-back, over-ear design of the M40x gives you excellent passive isolation to keep out exterior noise, with minimal bleed. Critically acclaimed M-Series professional monitor headphones deliver accurate audio and outstanding comfort, perfect for long sessions in the studio and on the go.
/ Flexible Listening
Two Cables
ATH-M40x includes two detachable cables — a 3M straight cable and a coiled cable that can stretch from 1.2M to 3M — for flexible use both in the studio and at home. Each cable terminates in a 3.5 mm mini jack, and a 6.3 mm (1/4”) adapter is included for use with source equipment that requires it.
