Many ear doctors also highly recommend them, because they are better and healthier for ears. 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. Finally, we can hear the sound. In the process of sound transmission, they directly bypass the ear canal and eardrum to reach the inner ear, taking a shortcut. Just because it takes a shortcut, it reduces the damage to the ear canal and eardrum, making it the healthiest headphone. Most of us have been exposed to bone conduction in our daily life. Put your ears close to the ground, and you can hear the footsteps of “tap, tap, tap” through vibration; cover your ears, and you can still hear yourself mumbling, which is a natural phenomenon of bone conduction. While bone conduction headphones are popular, they’re not perfect. They also have some disadvantages, summed up in three: Disadvantage 1 : sound quality Because of the design characteristics of bone conduction headphones, their anti-interference effect is not ideal when wearing them for shopping, subway, car and other noisy environments.
