The difference compare to regular headphones:
Traditional headphones send sound through your eardrums. Bone conduction headphones send sound through the bones of your skull. Rather of speakers, bone conduction headphones have transducers that send vibrations through your cheekbones to your cochleas, so your eardrums are free to take in your surroundings. The cordless headset microphone provide you convenience of calling and listening to the music while doing sports or outside activities.
