Its biggest feature is that it uses bone conduction to transmit sound, uses human bones as the medium for transmitting sound, and directly transmits sound to the auditory nerve to form hearing. This distinctive technical feature has also revolutionized the way it is worn. The wearing method of bone conduction headphones has changed from traditional in-ear wearing to hanging ear wearing. When wearing it, you only need to hang the earphone on the auricle and put the vibration unit close to the temple, and the whole ear is completely open. The change in the way of sound transmission and wearing has made bone conduction headphones another type of earphone, which is a huge upgrade compared to traditional earphones. Many ear doctors also highly recommend them, because they are better and healthier for ears. How does bone conduction headphones work? Bone conduction headphones are a new application of proven technology, but bone conduction has a long history, with its first applications dating back to the 18th century. It is rumored that Beethoven, who was deaf, rubbed one end of a long rod into the piano. He put the other end in his mouth and kept it as close to the ear as possible. When playing, the long rod transmitted the sound to the jawbone and the cochlea of the inner ear, so that Beethoven could hear the sound of the piano. This was so important for Beethoven cause he regained his sense of hearing again and he can continue his music composition. This may be the earliest documented application of bone conduction technology. ​ When the bone conduction headphone works, it converts the sound signal into mechanical vibration by the sound unit and drives the skull to vibrate at the same frequency, allowing the sound to reach the cochlea of the middle ear and inner ear.
