SENNHEISER HD 660 S2

Dynamic open-back headphones with crisp bass, excellent mid-frequency response, and a sweet, natural treble. The new transducer has better control of diaphragm movements thanks to a specially manufactured precision stainless steel fabric. The extremely light aluminum voice coils ensure maximum fidelity of the impulses. Transducers are carefully selected and hand-matched to ensure consistently tight tolerances (±1 db). The hd 660 s reveals its full potential optimally when connected to the balanced outputs of a dedicated headphone amplifier such as the hdv 820 or the balanced output of a mobile digital audio player. As a result, it comes with a choice of cables made from highly conductive ofc copper (very low handling noise and robust para-aramid reinforcement) for any occasion. The elliptical ear cups of the HD 660 S2 are shaped to follow the anatomy of the ear, while the thick padding on the headband and the replaceable ear cushions guarantee hours of listening in maximum comfort.
