The Audio-Technica ATH-M70x Pro Monitor Headphones use proprietary 45mm large-aperture drivers with rare-earth neodymium magnets and copper-clad aluminum wire voice coils to deliver an extended frequency response of 5 to 40,000 Hz. Their closed-back circumaural design follows the contour of the ear to help isolate from environmental noise and makes them suitable for studio mixing, tracking, FOH, DJing, mastering, post-production, audio forensics, and personal listening.
