I have been riding for about 24 years since I was a kid and I have now found the enjoyment of music while riding. Before anyone starts lecturing; I know the repercussions. I don't have the music up loud enough to drown out any of the sounds that are needed to keep my attention. My problem is I purchased the Sansa unit and it's wonderful. The earplugs are not the best though. They don't fit very well inside the ear which leads to more wind noise and thus a louder volume. I read somewhere that the ETYMOTIC ER-6I NOISE ISOLATING IN-EAR EARPHONES work really well. They are kind of pricey but I have read good things about them. I was curious if anyone had used them and how they fit inside the helmet.
