How To Replace a Headphone Plug

Your headphones have stopped working, and after troubleshooting the problem, you realize the plug is broken. Replace the plug and get back to enjoying your music in private.


  • Step 1: Solder the wires to the replacement plug. The ground copper wire is soldered to the longest pin, and the other two wires to the other two pins.
  • Step 2: Test the headphones by plugging them in. If they are working again, screw the outer case of the replacement headphone plug back on; if they aren't, well then maybe it's time to buy a new pair!
  • FACT: Jazz musician John C. Koss invented stereo headphones in 1958 so that listeners could enjoy hearing music from a portable phonograph without disturbing those around them.
  • TIP: Wash your hands before soldering the wires as the oil from your hands can affect how well the wires solder together.
  • Step 3: Tin the three wires of the cord by adding solder to their ends. Cover the ends of the wire completely, but don't add so much that it starts to drip.
  • Step 4: Cut the cord at the weak point with the wire cutters, and strip the insulation to expose the wires. There should be a right, left, and a copper ground wire.
  • TIP: For headphone cords made of two cables, there will be two copper ground wires. Twist the two ground cables together.
  • Step 5: Unscrew the casing from the replacement jack and slide it onto the cord.
  • Step 6: Test the headphone cable for the break by bending the wire around until the sound cuts off or crackles.
