Bluetooth headset in charging when the indicator light is not bright, there may be a Bluetooth headset you use for a long time, the headset itself has a self-protection function, in a \"closed\" state, if this happens, you can charge a few minutes or dozens of minutes to see if the indicator light is bright, if not to see whether it is plugged in, If all else is fine, consider your headphones.

The main reason why the Bluetooth headset cannot be turned on normally should be the lack of power, charge it to see if it can be turned on.
