If the headset wireless Bluetooth can not be charged for a long time, you first need to check whether the charger and charging cable are working properly. If there are no problems with the charger and charging cable, you can try to use another power socket for charging, or use a new charging cable. If none of these methods solve the problem, it may be that the headset battery has been damaged and needs to be replaced with a new battery. At the same time, it is also necessary to pay attention to the need to turn off the headset switch before charging, so as to avoid excessive battery consumption.
