The FreEar Sunglasses™ - Bone Conduction Polarized Sunglasses use a cool technology called bone conduction to transmit audio to your brain. Bone conduction is a way of sound conduction which transfers sound waves through the cranium, bony labyrinth, inner ear lymph fluid, auditory nerve to the auditory center. We can hear the sound using bone conduction while keeping our ears free to hear the surrounding.
- Bone Conduction Principle - Bone Conduction speaker transmits sound waves to the skull via vibrations directly to the auditory nerve. This lets you hear external sound when listening to music. Usage is very safe, it will not cause damage to the ear canal and eardrum and it doesn't affect other people because the sound waves diffuse in the air, only the wearer can hear.
