Product Details

Technical Features

The HD 650 is a pair of top-of-the-range open, dynamic hi-fi stereo headphones with extremely lightweight aluminium voice coils that ensure excellent transient noise. Each HD 650 features hand-picked systems with narrow tolerances (+/- 1dB), and specially developed acoustic silk for precise, uniform attenuation over the entire area. The specially modulated detachable connecting cable made from highly conductive OFC copper ensures low structure-borne sound sensitivity.


With an elliptical design adapted to the shape of the ears, the HD 650 is exceptionally comfortable to wear. Boasting a high-quality titanium/silver finish, the HD 650 is not only comfortable to wear, it also looks good.

With a 6.35mm stereo jack, the HD 650 can be connected directly to stationary hi-fi components of the highest quality, in particular SACD, DVD-A and CD players.
