Designed to satisfy the most discerning music lovers, the Audio-Technica AD900X is a great choice for those who like the spacious quality of open-back headphones and the comfort necessary for long listening sessions. The 53-millimeter dynamic drivers were specifically designed for this model, with rare-earth magnets and the company’s copper-clad aluminum-wire (CCAW) voice-coil technology for superior audio reproduction and an extremely wide frequency response. The result is an immersive listening experience with clear, natural vocal and instrumental reproduction, plus a smooth tonal balance, precise imaging, and excellent dynamic range. For a uniquely comfortable fit, the AD900X has generously cushioned ear pads, a lightweight honeycomb aluminum casing, and 3D Wing Support, which adjusts perfectly to each wearer.
