Audio-Technica ATH-M40x Professional Monitor Headphones — Refurbished (Restored)

Restored Audio-Technica ATH-M40x professional monitor headphones, rebuilt and tested for reliable performance. Constructed with durable materials and precision engineering, they utilize 40 mm drivers with rare earth magnets and copper-clad aluminum wire voice coils. The response is tuned flat for incredibly accurate sound monitoring across the entire frequency range. A circumaural earcup design wraps around the ears to provide effective sound isolation in loud environments, and the earcups swivel 90° for convenient one-ear monitoring. Professional-grade earpad and headband materials increase comfort and long-term durability. The design also collapses for compact, space-saving portability.
