The sound quality of these headphones is really outstanding. This was however found already in various reviews, that's true extent. What interests me here more ergonomic since you usually already has the device for a while at the top. First and foremost: try best in the shop if you really appeals the clamp behind the ears! The temple always exerts the Sennheiser might find unpleasant pressure on the head so that people with a big head or the 'wrong' shape of the head, either immediately or after several minutes Wear For additional fastening each a plastic strap serves also may begin to press when your ear is incorrect "fits" The very light headset acts not too high (cheap plastic but a matter of taste) and the connecting cable from the speaker to the bracket is so tiny that it snaps securely fast times with no proper care or transport in a backpack without protection. Another flaw is the open design. The headset can not be used if you want to hear something in public transport of the music yet. Regardless of the headphone is kept with which side to his ear, it's almost identical. The single-sided cable minimizes cable chaos on the body, but is standard. The cable is sufficiently long and has a 3.5 mm jack.
