The charge is full or the battery is dead. Bluetooth headset how to charge choose the right charger. Generally, Bluetooth headsets have a dedicated charger, if there is no dedicated charger, you can find the charging interface (some are thin and round holes, some are MiniUSB universal interface) the same, and rated output power of the same charger to use. When charging, you should plug in all the plugs, not only more than half of them, so that the machine will be damaged for a long time. When inserting and removing the charging plug, it should be light, otherwise it will cause the plug to loose over a long time. If the Bluetooth headset is plugged into the base or charging box, the charging time is longer than that directly charged to the Bluetooth headset. The charging method is the same as charging the headset directly, and you can align the charging cable with the hole in the base and plug it in. When the charge is on, the red indicator lights up, indicating that it is being charged. If the charging is complete, the indicator will turn blue, and the charger can be removed. When charging the Bluetooth headset, try not to use the headset again to avoid accidental damage.
It doesn't match. Bluetooth headphones can generally be used with ordinary charging cable, unless your Bluetooth headset current and the required voltage line is different, the supplier is specially equipped with a charging cable, it can not be charged! Like the car Bluetooth headset I bought before, it is directly used in the car, and it is directly plugged in and charged in the car.
If you want to use a special charging cable corresponding to the headset, one side is a small plug and the other side is a normal USB jack. If it is an ordinary headset, you can directly use the general charging cable.
