Key strengths
beyerdynamic's specification sheet lists microphone data — cardioid back-electret condenser, 20–20,000 Hz, 21.6 mV/Pa and an approx. 190 mm boom — alongside the headphone specifications.
One cable serves PC (separate headphone and microphone plugs) and, with the supplied adapter, consoles and phones with a combination jack.
Ear pads, headband pad and cable are offered as replacement parts, and the headband cushion has a fontanelle recess.
Before you buy
It is open-back: beyerdynamic recommends the closed MMX 300 PRO where other players are in the room and no sound should escape; no attenuation figure is published for the MMX 330 PRO.
It is analogue only (no USB or wireless), and beyerdynamic's sources disagree on whether the cable has an integrated remote.
Every specification. With its source.
