Sennheiser Headphones Wired HD 660S2 Black Open Type High Performance Transducer Ultra Light Voice Coil Vent Magnet System []

A rich sub-bass is added to achieve a natural, yet high-fidelity sound: An ultra-lightweight aluminum voice coil with an impedance of 300 Ω is used to reproduce excellent impulse response and high-quality sound that is familiar to the ear. Transducer with efficient airflow: Unique vent magnet system improves airflow inside the transducer, and internal steel mesh eliminates unnecessary distortion. By doubling the sound pressure in the lowest range, sub-bass, mid-bass, and higher frequency bands are reproduced with high precision and balance. Percussion instruments and electronic music will become more rewarding to listen to. The ear pads are a combination of soft padding and velor, and fit your head with moderate lateral pressure. The open design uses ergonomics to eliminate any discomfort and provides the same comfort even when listening for long periods of time. High quality, designed in Germany and manufactured in Ireland. The playback frequency characteristics are 8Hz - 41,500Hz, and the cable is 1.8m long, perfect for desktop use. Manufacturer's 2-year warranty (limited to new purchases from Amazon LLC)
