There are several reasons why Bluetooth headphones cannot be charged:
1. The charger is broken or the socket is in poor contact. It may be that the use of the charger for a long time makes the charger socket loose and the poor contact results in the inability to charge the Bluetooth headset normally. I suggest you try a new charger.
2, Bluetooth headset charging port loose contact caused by poor. Check the charging port of the Bluetooth headset, whether there is loose, poor contact, resulting in normal charging.
3, the Bluetooth headset battery is damaged, resulting in no charge. If the charger is good and the interface is not loose, it is necessary to consider that the battery is damaged. May be long-term use, resulting in battery aging, resulting in battery damage can not be charged normally, use.

1, first of all, to choose the right charger. Because the general Bluetooth headset has a special charger, if there is no special charger, you can directly find the charging interface (some are thin and round holes, some are MiniUSB universal interface), and the rated output power is also the same charger to use.
2, secondly, the charging time of the general Bluetooth headset is kept within 2 hours, because the charging time is too long, it will directly lead to the aging or even burning of the machine circuit board, and there will be a variety of inexplicable machine failures, such as shortened standby time, frequent disconnection, shortened call distance, and unable to turn on the phone. So, for the sake of your Bluetooth headphones, please give them a proper charging time.
3, then, when charging to plug in all, do not only plug in more than half, such a long time of use will cause damage to the Bluetooth headset. Of course, when pulling the charging plug, the action should not be so big and so rude, but be gentle, otherwise pulling the plug for a long time will cause the plug to loose.
4. Then, when the Bluetooth headset is connected to the power supply and starts charging, the red indicator light on the Bluetooth headset is long bright, indicating that it is charging. If the indicator turns blue after charging is completed, the charger can be removed.
5, if the Bluetooth headset plugged into the base or charging box charging, and directly to the Bluetooth headset charging, the charge after the completion of the charge will be more durable in the use of time.
6, finally, after charging the charger of the Bluetooth headset, remember to unplug from the plugboard, if it is plugged into the power for a long time, it will directly and seriously affect the life of the charger
