ATH-A2000X closed-back dynamic headphones use elite materials and design characteristics that push to the finer limits of audio playback quality. Large 53 mm drivers with Permendur* magnetic circuitry and bobbin-wound OFC-7N voice coils deliver unmatched expressive power and incredible sonic detail. High-rigidity titanium housings and a lightweight magnesium alloy frame are an ideal choice for virtually lossless audio. ATH-A2000X headphones come with Clarino**, a carefully engineered leather that is extremely durable, yet amazingly soft to the touch. The cords used are 99.99999% oxygen-free copper, more pure than regular copper wire. The result is an uncompromised listening experience for the most discerning audiophile.
