1. There is a problem with data cable insertion. Many people will have some bad habits when using data lines, such as plugging the data line backwards, straining the connector of the data line, pulling the data line too long, and so on.

2, the data cable is not packed. Most people throw aside the data line when it is not used, and after a long time, the joint is easy to enter the ash, thus affecting the service life of the data line.

3, bought a poor quality data cable. We all know that the original data line is of course the best, the higher the efficiency of the charging line, many people after the original data line is broken, bought a miscellaneous brand, inferior data line, naturally easy to break.
It may be that the rechargeable battery of this Bluetooth headset is broken, it may be that the circuit board inside him is burned and short-circuited, which will cause the charging hot and can not open the machine. You'll just have to get it repaired.
Maybe it's worn out because it needs a new one
