Yes, the earphones have internal batteries. You initially have to charge them before they begin working. The batteries only last for six to ten hours. Then need recharging. Plug a USB adapter into the home lighting switch connect to the headphones. A red light will show the head phones are charging. It will go of when the head phones are fully charged.
