Open Dynamic Headphones
SENNHEISER HD660S are robust and lightweight open dynamic headphones, yet capable of offering an extremely natural and real listening experience thanks to the latest generation transducer that minimizes harmonic distortion. Extremely versatile, they guarantee high-fidelity listening from both stereo systems and high-resolution mobile devices.
The SENNHEISER HD660S were developed from the previous HD 650 model: the transducers are hand-selected and assembled to ensure the same sound quality in both earcups (with a tolerance of approximately 1 dB). They ensure maximum fidelity in the reproduction of the highest notes, clear and well-balanced bass, excellent response in the mid-frequencies, and extremely natural highs. With an impedance of 150 ohms, the SENNHEISER HD660S can be used with high-resolution mobile players or connected to HiFi stereo systems. They express their full power when connected to amplifiers with balanced outputs, such as Sennheiser's HDV 820 or other digital players. They are equipped with OFC copper cables with both 6.35 mm jacks and 4.4 mm Pentaconn connectors, as well as 6.35 mm and 3.5 mm adapters.
