USER MANUAL HD 650 SENNHEISER

With the HD 650, Sennheiser has followed the changes in the listening habits of music-lovers and the way in which they experience sound. In spite of all purism and the highest demands on precise sound reproduction, a slight change in listening behaviour is detectable.
