The following content can be ignored: Bone conduction headphones are a new type of headphones that transmit sound directly to the inner ear through bone conduction technology, instead of outputting sound through the ear canal like regular headphones.
The working principle of bone conduction headphones is: it uses a small vibration plate to directly transmit the sound vibration signals to the skull, and then the skull transmits the sound to the inner ear to achieve sound reception.
Its main advantages are: it will not obstuct  external sounds from coming in, so it allows receiving external sounds while using safely; as it does not output sound through the ear canal, the volume can be lowered significantly without disturbing others; and it is suitable for various scenarios such as exercise and work, making it more flexible and convenient to use.
