The Bone Conduction Headphone is that they are wireless or wired headphones that sit on your temples, allowing you to perceive sound through vibrations. The technology was discovered in the 18th century by the classical composer, Ludwig van Beethoven, who realized that by fastening a rod to his piano, he could “hear” sound through clenched teeth.
As he was deaf. this was quite the breakthrough at the time.
The technology once again proved itself in the early 1900s, when Hugo Gernsback invented the Osophone, which was the first bone conduction hearing aid. One of the pros of using bone conduction headphones is that it promotes situational awareness, allowing you to be conscious of your environment while outdoors.
