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° swiveling ear-cups and softer yet sturdy materials for the headband and the ear pads ensure outstanding levels of comfort. The fold-away design makes it easy to store and transport.
