The usual thing to do when a headset stops working is to throw it away and buy a new one. In this tutorial, I teach you how to repair almost any headset.

To begin with, you will have to identify the fault, in this case it is easy as it is in the 3.5mm male jack. In other cases, it could be in any part of the cable, so you would have to bend it until it sounds, at that moment, you have already found the problem.

Also, it could be the split solder or the weakened cable, inside the headphones. In that case, the repair is a little complicated, since, depending on the model, it may be unfeasible to open them.

Here are the links to the connectors:
