Retail Price: 6,299 Erssimo Bone Conduction Bluetooth Headphones Ear-Open Design Erssimo bone conduction headphones do not block the ears, allowing you to hear surrounding sounds and enjoy music while conversing. They are comfortable to wear for extended periods. Bone Conduction vs. Regular Headphones "Bone conduction" transmits vibrations directly to the inner ear through the "bones," delivering sound to the brain. It protects the ears without damaging the eardrum. Since the ears are not blocked, ambient sounds can be heard even during playback, preventing hearing loss. Regular headphones transmit sound vibrations from the ear to the eardrum, which the brain then recognizes as sound. Wearing them for extended periods can cause earaches or headaches.
