Bluetooth has a number of Benefits. It allows file transfer between two people (mobiles) such as music, photos etc. relativley quickly. Bluetooth works to connect your phone to another electronic device so can be used to connect the phone to wireless headphones, wireless bluetooth headsets (handsfree).
