Product Description:
These helmet speakers are thin, provide high volume, and are uniquely designed for helmets. They plug into any radio, MP3, or CD player that has a standard 1/8" output jack. They are very comfortable inside your helmet. Just press them into your helmet's ear pockets or secure them to the helmet lining with the attached Velcro or adhesive Velcro pads. Use these speakers with any helmet that covers your ears.

Rating : - Not Loud Enough
I agree with many of the other reviewers. Definitly NOT loud enough, I tried them with my Ipod and my Garmin - neither was loud enough. I had to go with in ear phones.
