“cardo BK-1 - Hands free communication that allows you to talk with your friends while riding. The headphones do not sit directly over your ear so ambient noise (traffic, horns, motorbikes, other cyclists calling out from behind you, etc.,) is not blocked out. These headphones are much safer than wearing a set of earbuds for cyclists.”
