for me all im doing is replacing wind noise. drives me crazy. the head phones i use i can still hear traffic, still less of course. which also keeps me out of trouble IMO. when some cool kid yells somthing profane at me, i cannot understand it and i dont chase the car. when i ride solo only, do i wear my ipod. i dont know what people are thinking when they are listening to music when around other people. i had a guy get upset with me when he was talking to me because he couldnt hear me. go figure
