The heat generated by charging the Bluetooth headset is estimated to be the heat emitted by the power management circuit of the headset during the conversion of voltage and current. It does not rule out the reason of excessive charging current.

Stop charging and wait for cooling. ## When charging, part of the electric energy will be converted into heat energy; When the current passes through the conductor, it will also generate some heat, and a slight scalding is a normal phenomenon, please rest assured.

If the feeling of hot situation is particularly obvious, it means that your charging current is too large, to change the charger hope to help you ## It is estimated that the internal circuit is faulty, Bluetooth headphone charging current is generally not more than one hundred or two hundred mA, the current is not large, will not lead to heat. Charge it. If it breaks, it doesn't work. If it works, keep using it. I can't fix this on my own.

I hope the answer can help you, first confirm whether the charge is full, my Bluetooth headset has also had what you said, but a little bit of heat is normal, wait for half a minute to charge and confirm that the charging light is gone, indicating that the charge is full, restart OK. If it's hot, there's a problem. It's probably the power management circuit for the headset
