If you are curious as to what the future of the headphone will be, then you are going to want to check out the BRS Earbuds. The BRS Earbuds (Bone Radio System) use bone conduction to transmit high quality sound to your ears no matter where you are or what you're listening to.
The BRS Earbuds wrap around the ear and transmit sound through the small bones in the ear. The device has only two buttons: an on/off switch and a switch that controls the LED lamp.
It may be a little too early to tell, but it looks like bone conduction (transmitting sound through the bones of the ear) is going to be heavily incorporated into the headphones and earbuds of the future. Bone conduction is said to give a clearer sound and to prevent hearing damage associated with jamming high-powered earbuds deep into the ear canal. Don't be surprised if you see a pair of BRS Earbuds by Dre hit store shelves in the near future.
