Introduction
If you have no sound in the earphones or it wobbles between right and left earphones, there is an issue with wires in the earphones. If you notice that the sound changes when you move around the audio jack, replacing the jack would fix the sound issue. In order to replace an earphone connector, you would need to cut off the old connector and solder the new connector with the wires of the earphones. Please follow safety rules when using soldering equipment.
