There's always the sitcom joke about people accidentally getting radio reception through fillings or metal plates and the like. But would you ever knowingly ask for such a thing?

"...The SwiMP3 uses bone conduction to deliver audio. Bone conduction stimulates the fluids in the inner ear through any of the bones of the skull. The unit pulses soundwaves through the cheekbone."

Aaaaah! Keep your vibrating technology away from my face!
