REVOLUTIONARY BONE CONDUCTION TECHNOLOGY - This revolutionary Bluetooth headset uses advanced bone conduction technology to transmit music to the internal ear through the cranial bones - thus eliminating the need to put the headphones directly into your ears and the possibility of impairing your hearing capability.

Even the world class wearable technologies like google-glass are employing bone conduction technology in their devices to enhance the sound experience.
