Under normal circumstances, the Bluetooth headset indicator has three colors: red, green or blue. In normal use, the green light flashes slowly, and the red light flashes from time to time (it will also emit a \"beep\" sound, and the Bluetooth earphone with voice will directly announce: the earphone battery is insufficient.) It means the battery is low.
When the Bluetooth headset is charging, the light is on, but it is not charged may be poor contact, the reason for not connecting may be because the built-in program of the Bluetooth chip of the new headset is not activated, or the number of memory connections of the headset is full, the charger output voltage is too large or too small, the standard should be between 3.5-5 volts. You can try to change a data cable first. If the battery is in poor contact, or the protection board is damaged, you can check it with a voltmeter, or it may be the internal line is damaged. If you can't handle it yourself, it is recommended to hand it over to after-sales service.
