The Bone Conduction Headphone Vonia EZ-4200P does what normal headphones do - they let you 'listen' to music. They do this, however, by vibrating your ear bones. I thought we had already accomplished this with the pounding of bass.
"Bone conduction is the conduction of sound to the inner ear through the bones of the skull. â€œBone Conduction Headphoneâ€ transforms electric signals to mechanical vibration and transfer sounds to the internal ear through the cranial bones."
