Sennheiser HD-650

Sennheiser HD-650 - dynamic open-back hi-fi headphones with circumaural design (covers the ear lobe), designed to provide a true audiophile experience with natural open sound. The lightweight aluminium voice coils ensure remarkable transient response, while the full-range drivers deliver a frequency response from 10 to 41000 Hz. They offer a comfortable design due to their elliptical shape, which naturally adapts to the shape of the ear.

HD 650 uses a detachable 3 m cable made from highly conductive OFC copper conductors, with low noise. The headphones can be used with high-performance mobile devices and can excel with high-quality hi-fi components such as SACD players, DVD-A, and CDs. HD 650 is delivered with the detachable cable and a 1/8" to 1/4" adapter.
