When the indicator light of beats Bluetooth headphones is not on while charging, there should be the following two situations:
The first case is that the headset is completely out of power, so it does not show the charge when it is just connected to the power supply for safe charging, and the indicator light will turn on after a while;
The second case is that the hardware such as the power supply or headset box fails, at which time professional detection and maintenance is required.
It should be that the charging cable or electrical source of the Bluetooth headset is short circuited and cannot be used normally.
