Product Features:
Bone Conduction Headphone:
This audio sunglasses have been equipped with high-tech bone conduction technology, which decodes sound waves and convert them into vibrations that can be received directly by the Cochlea, and bypasses the eardrums.
To have better understanding and distinguishing, you can use the earplugs provided in the box, and play music or answer call. Though your ears are covered, you can still clearly hear the sound. We recommend you keep volume at 50%-60% for best listening experience; Maximum 100% volume may lead to echo during calling, or even lead to sounds transfer to people near you by air.
