Prepare the Soldering Iron: Plug in and heat up your soldering iron. Ensure it's clean and ready for use.
-
Remove the Old Plug: Carefully cut away the old jack plug if it is still attached. Use wire strippers to expose the wires inside the cable.
-
Tin the Wires: Lightly tin the exposed wire ends by applying a small amount of solder. This makes it easier to connect to the new jack plug.
-
Attach the Wires to the New Plug: Identify the corresponding terminals on the new 3.5mm 4-pole jack plug (ground, left, right, microphone). Solder each tinned wire to its corresponding terminal.
-
Inspect the Connections: Double-check the solder joints to ensure they are secure and that no wires are crossing or shorting out.

-
Prepare the Heat Shrink Tubing: Select an appropriate size of heat shrink tubing that will fit over the soldered connections and the base of the plug.
-
Slide Tubing Over the Wires: Before fully assembling the plug, slide the heat shrink tubing over the wires and position it near the soldered connections.
-
Apply Heat: Use a heat gun or the side of the soldering iron to gently heat the tubing until it shrinks tightly around the wires, providing insulation and strain relief.
-
Reassemble the Plug: Once the tubing has been shrunk, carefully reassemble the plug casing over the soldered connections.
-
Test the Connection: Plug the jack into a compatible device to ensure that all connections (audio and microphone) work as intended.
-
Reverse the Disassembly Process: Follow the steps in reverse order to fully reassemble your device. Ensure everything is securely in place and that no components are left loose.
