Headphones very comfortable to wear in the city, remains compact and discreet. Average sound quality (lacking some momentum and treble). Very nice quality cord (ultra flexible and do not kink). Folded, the helmet takes up very little space in a backpack or even a large pocket. The iPod Remote / iPhone was sometimes misfires (more than volume control) but remains convenient and well placed. Clever, the jack on the right earpiece to share his music. I would have preferred the descent Cable on that side ... usual question taken with Apple earphones
