i got these mainly to listen to while i was skiing, but i tried them on and i was very impressed with the construction of the headphone and the sound quality of the 57mm drivers. the over ear design is practical and comfortable, and they dont make you look like a total dork. the speaker its self fits inside any RED helmet and they also fit inside some of the K2 Edge helmets. the cord for the helmet application has a mute and volume nob on it with a clip for your jacket. the headphone wire is about 5ft long and is coiled in the mid section.
