Jabees HearLink Hearing AID Kit Open Ear Wireless headphones + MIC Bone ConductionBone Conduction Technology: In bone conduction headphones, sound is transmitted as vibrations through the bones of your skull (typically the cheekbones), bypassing the eardrum, and directly stimulating the inner ear. This allows the ear canal to remain open so you can hear your surroundings while listening. Microphone Transmitter: A mic transmitter (or just mic) can pick up your voice and send it wirelessly (via Bluetooth) or wired to another device.
