What is a bone conduction?
Bone conduction is a way of sound conduction which transfers sound waves through Cranium, bony labyrinth, inner ear lymph fluid, auditory nerve, auditory center. We can hear the sound using bone conduction every day. 

Note: There may be an external sound, please pay attention to the protection of personal privacy.

From a professional point of view, it is not a leak, it is the second sound, So we developed the fourth generation of technology, we use this technology to reduce the leakage of 87%.
