While bone conduction headphones offer a unique way to deliver sound by bypassing the eardrum, they still rely on transmitting vibrations to the inner ear for auditory perception. This process involves emitting frequencies and vibrations that reach the cochlea, ultimately leading to sound perception through stereocilia vibrations.

However, because bone conduction headphones lack a complete seal over the ear, some sound leakage occurs. As a result, those nearby may hear a portion of the audio being played. Despite their innovative technology, the inability to form a tight seal contributes to sound leakage, allowing others to hear what you’re listening to.
