I use a pair of $11 Maxell's I got at walmart with various sized rubber ear plugs so they really block out alot of wind noise, I think that's key. That way you don't have to blast the music to be able to hear it. Plus the pair I have, has a mic so I can make quick calls at gas stops by plugging the headset into my phone and not have to remove my helmet. I clip a gen2 ipod shuffle onto my helmet chin strap. Or sometimes I'll put my phone in my gps case on the Ram mount and plug into it for music.
