Bone conduction is a natural way of hearing and we actually experience it every day; when we speak, our ears are picking up sound via our skull. Trying covering up your ears and saying something. Congrats—you’ve just tried bone conduction! Traditional headphones use speakers to vibrate the air to send to your eardrums. Bone conduction uses transducers that convert electrical signals into vibrations that travel through bone and directly into the inner ear, bypassing the eardrums. This is why bone conduction—when applied properly—can offer superior audio quality even in noisy environments. The first time you listen to someone’s voice through your finger, it’s unlike anything you've tried before. People have described the experience as everything from having a voice in your head, to feeling like a spy on a mission because you can only hear it when you touch your ear. The vibrations on the finger are very light, almost like a tickle, which you get used to very quickly.
