Anyone have any success with open face helmets? I bought a creative MP3 player with earbuds and then bought some behind the head headphones that had a very high SPL (sound pressure level) rating, but no matter what i did after 35-40MPH i literally couldn't tell if it was on even with the volume all the way up ! I wonder if those speakers would help cut wind noise while providing ample volume w/o killing my ears. At this point since i have little use for a MP# player it seems i threw $80 down the toilet.
