PRO9 is not an ordinary Bluetooth sports headset, but a bone conduction Bluetooth sports headset. The biggest difference between bone conduction earphones and traditional earphones is that traditional earphones emit sound waves from a horn, and the vibrating outside air conducts sound through the eardrum. Bone conduction is a vibration wave generated by a vibrator that vibrates through the skull and transmits the sound to the auditory nerve. This product uses the British CSR high-end stereo Bluetooth chip, with customized high-quality vibrators, different sound transmission methods, let us experience a different auditory feast.
