Yes, the AirPods can connect while charging. When you place AirPods in a charging case and connect them to a power source, they automatically start charging. You can still pair them with your device and use them during the charging process. This means you can continue to enjoy music, take calls, or use other features while charging without interruption. This makes AirPods a very convenient and flexible choice for wireless headphones.
AirPods can not be connected to Bluetooth when charged, and only one of the two functions can be selected.
