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.

Use wire cutters to remove the audio jack. Use wire cutters to remove approximately 1/2 inch of insulation of the wire and separate the four wires inside of it.

  • Using Digital Multimeter in the "Continuity" mode, place two probes on the soldered wires of the same color. You will hear audio signal indicating that there is a connection.

  • Repeat this for each of the wire colors.

  • If there is no Multimeter signal, you will need to resolder the wires and to make sure that wires of different colors are completely separated.

  • After all wires are soldered, cover them with shrink tubing.

  • Use the heat gun to shrink the tubing and fit it tightly around the wires.

  • Gently apply heat in order to shape the tubing around the soldered wires.
