Bone-Conduction technology is not a new thing. Bone-Conduction means a sound wave is conducted through your skull by vibration and further to inner ear so you can hear the audio. In fact, back in the early 1980's a company called JS&A sold a product that allowed you to do just this with transistor radio.

Various other multimedia functions such as built-in 1.35 mega pixel camera, games and IrDA communication round out the phone.
