plug/jack on end of cord broke off.

Hi,

You need to replace the jack plug as they cannot be repaired.

Carefully slice open and remove the plastic (rubber?) covering the old plug so that you expose the wiring connections and can view what colour wires are terminated on which connector in the plug. The wire to the sleeve connection may or may not be soldered to a terminal point. It may be stripped to bare wire and doubled back inside the “barrel” entry of the plug and jammed between the cable sheath and the barrel of the plug (which is usually the sleeve anyway).

Write it down or take a picture or both!!

Doing this will save you a lot of grief when going to wire in a new plug to the cable.

When you have got a new plug (check on Ebay etc for 3.5mm TRRS plug - TRRS just means Tip, Ring1, Ring2 , Sleeve indicating a 4 pole plug - assuming it is a 4 pole plug which allows for a microphone with the headset and not a 3 pole plug then it would be 3.5mm TRS plug) cut the cable off the old plug close to the plug to retain the maximum length of cable possible and then strip the cable sheath back from the cut end about 50mm (2”) to expose the colour insulated wires. Terminate the wires on the new plug as per the colours that you found on the old plug and had written down or taken a picture of.

There are videos on YouTube showing how to terminate headset plugs etc.
