4, if charged, the red indicator light will light up, charging is completed, the indicator light will turn blue, and then take it down.
It can be charged with a matching usb cable.
If you break it, buy a new one. It's broken and you can't charge it.
The earphone case is broken and you have to buy a new one because you can only charge the earphone with the earphone case.
Look at the structure, the interface line that leads out of the wire is not broken, you can continue to charge, find glue to glue the interface again.
If the interface is welded to the circuit board, it cannot be done, and it must be welded and reconnected to the charging line to charge
