SOUNDBONE is an innovative headphone with a built in bone conduction oscillator which offers less sound leakage compared to conventional headphones. The headphone turns sound waves into vibrations and transmits them to the ear via the skull. Unlike traditional headphones, this product will not damage your hearing no matter what volume setting you use!
These headphones use conduction sound waves, but the headphone still goes in the ear like a traditional headphone. SOUNDBONE headphones recognize and transmit much broader and deeper sound than traditional headphones.
