Richard Solo's FreeWheelin audio system (US$150 street price) allows you to add stereo speakers to your bike helmet. As the picture to the right shows, it consists of three small boxes that use a high-powered variant of Velcro to mount to the helmet's back and sides.
It's about as dorky looking a product as you could imagine but dang if it doesn't deliver really fabulous sound.
I hooked up my test unit to USB power for a few hours before taking it all for a spin on my bike. Charging is really easy, but you either have to hook up your entire helmet or dismount/remount the speakers and control box from their attachment areas. It's not a big deal either way, I found. Pairing the Bluetooth was also super-easy.
