The black ATH-M40x Monitor Headphones from Audio Technica are designed for use in studio tracking and mixing and well as for DJ monitoring applications. They feature 40mm Neodymium drivers with copper-clad aluminum voice coils tuned for a flat response. The headphones have a circumaural, around-the-ear design that provides sound isolation in loud environments. The ear cups on the ATH-M40x can be swiveled up to 90 degrees, allowing for single-ear monitoring. The headphones have a detachable single-sided cable system, and both coiled and straight cables are included. When not in use, the ATH-M40x can be folded down and stored in the included carry pouch.
