If your Apple headset can't charge, try the following:
< br >
1. Check whether the charger supports Bluetooth headset charging, if not, please use a dedicated charger.
< br >
2. Check whether the charging port is clean. If dirt exists, use a cotton swab or cleaning tool to clean it.
< br >
3. Reconnect the Bluetooth headset to the charger and make sure the connection is secure.

4. If the above methods cannot solve the problem, it is recommended to contact Apple customer service or go to Apple authorized repair center for handling.
The reason is that 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.
