The ATH-AP2000Ti over-ear headphones feature proprietary large-aperture 53 mm drivers, a permendur magnetic circuit, and diaphragms with a diamond-like carbon (DLC) coating, enabling them to deliver exquisite, full-range audio, including the capacity to reproduce Hi-Res Audio. The headphones also utilize Core Mount Technology that optimally positions the driver unit within the housing to improve airflow efficiency. The efficient airflow helps the headphones reproduce highly transparent mid and high frequencies and rich, precise bass sound.
