The Audio-Technica ATH-AVA400 is an open-back, over-ear dynamic headphone designed for listeners who appreciate spacious, natural, and well-balanced sound. Its 40 mm drivers with CCAW (copper-clad aluminum) voice coils deliver clear mids and highs, with a smooth and airy soundstage — ideal for music listening, movies, or relaxed home audio sessions.
The honeycomb–punched aluminium housings and open-back design allow air to flow freely through the earcups, reducing resonance and delivering a wide, open soundscape — giving a more “room-like” listening feel rather than the closed-in sound of sealed headphones.
Comfort is prioritized: a self-adjusting headband adapts to your head shape for a secure fit, while soft cloth earpads reduce pressure on your ears — making ATH-AVA400 suitable for long listening sessions without fatigue.
A generous 3.0 m cable with gold-plated stereo plug (3.5 mm mini, with 6.3 mm adapter included) ensures easy connection to a variety of devices, from laptops and portable players to home stereo systems and dedicated amplifiers.
