ESCRIPTION
The DT 660 is a closed headphone that attenuates ambient noise
effectively and no sound from the headphone will be heard either.
The DT 660 features a most sophisticated sound with a detailed
reproduction of the deepest bass and brilliant highs. The 90° 
swivelling ear-cups and softer yet sturdy materials for the head-
band and the ear pads ensure outstanding levels of comfort. The
fold-away design makes it easy to store and transport. 
The DT 660 is still manufactured in Germany providing an excellent
quality.
