You know, how Beethoven continue musicmaking after he lost his hearing? He put a stick into his mouth and connect the other side of the stick to the piano, and he can still hear through bone conduction. Based on this principle,our R&D has launched a bluetooth headset with bone conduction function, can help people who lost his hearing but with good auditory nerve, and can provide perfect 3D sound at the same time. Specifications What are the features of bone conduction bluetooth headset? Listen more clearly even you are in a noisy environment. Folding design, easy to carry. 8 hours long play time U-shape design, more comfortable and stable 3D sound output with sound leakage dragon technology and dual microphone noise reduction CE and Rohs certification What's in the box? 1XBone conduction bluetooth headset 1xUSB Cable 2xEar plug 1xBuggy bag 1xUser Manual FAQ: What is bone conduction? How to hear sound: Under normal circumstances, sound wave get into the innner ear by air and bone conduction, then the inside and outside lymph of the inner ear vibrates, corti complete acoustic process, then the auditory nerve generate impulses and hand over to the hearing center, after comprehensive analysis of the cerebral cortex, finally hear the sound. Bone Conduction Principles: Bone conduction has movable and extrusion two ways, the two together can stimulate corti cause hearing, its specific way is: "sound waves - skull - bone side - the inner ear lymph - corti - auditory nerve - cerebral auditory center". Usually people don't need to use their skull to feel, but, when the outer ear and the middle ear changes pathologically, and let acoustic transmission been disrupted, the bone conduction may be used to compensate for the hearing
