Start off and state up front no where does this company claim that this device works with a motorcycle helmet. But I suspect that it may.

TuneBug Shake is a conductive speaker that attaches to a surface and it's the surface it's mounted to becomes the speaker. So the plastic and fireglass in your helmet that becomes your speaker, as the peizo electrics in the device vibrate the helmet and emit the sound. Really clever device, sound quality won't be that great, but it'd free up your ears to give you better auditory awareness as you ride. As opposed to headphones which is just plain dangerous.

I'm hearing impaired and would never use such a device myself, mostly due to saftey. I don't want to die just because I want to hear Billy Idol and rock out like a dork from the 80's. Nor would I care to die even if I had a better playlist.

The gadget is bluetooth so it can be mated up with a receiver or an iPhone or iPod Touch so there's no wires to dangle. The device affixes either a strap or thru adhesive pads mated to the helmet as illustrated in the skateboard helmet on the left.

Product sells for $119, if it works with a motorcycle helmet, could be a cool invotion for riders. If it does not work with motorcyle helmets, well then you've read this for naught!
