HD 660S2 Audiophile Open-Back Headphones

Crafted for discerning ears, the Sennheiser HD 660S2 offers a deeply immersive listening experience with refined acoustic performance and extended sub-bass response. Its ultra-light aluminum voice coils and 300-Ohm impedance deliver precise impulse control and rich, natural timbre, and the airflow-optimized 42-mm transducers and a vented magnet system help reduce distortion, revealing subtle textures and dynamic range across a wide frequency spectrum (8 Hz to 41,500 Hz). The open-back design enhances spatial realism, while plush ear cushions and detachable long cables ensure comfort and flexibility for desktop setups. Whether mixing, mastering or simply enjoying, the HD 660S2 brings studio-grade sound home!
