The easy fix, is to solder bridge the four pins I have marked with the red line. I hope this helps the next person!
I followed this advice and it works great! Both sides have equal volume and the microphone still works.

Five pins suggest a common ground. Seeing which of the five is common is the first step and it probably be the one that goes to the large area of print on the board. It will alson go to the 'ground' part of the headphone socket plug.

Having done that you need to short the other pairs. Locate one wire from the headphone plug and link it to one of the wires going to one of the earpieces. Its 50:50 that you will get the correct channel so listen to it and check. If wrong simple swap with the other earpiece wire. Now link the two remaining wires.

Job done... well not quite because there is the possibility that turning the volume control to one end will now 'short' the incoming audio. To avoid this you really need to either,

A/ Remove the pot.

B/ Turn the pot to the end that doesn't short the audio and then remove the knob.

C/ As B but just lock the knob with some hot glue etc to prevent it being turned.

Lets put the picture where we can see them

So I can only see one feed off to one earpiece. Where do the other earpiece wires go ?

Its a bit different to how I imagined tbh.

The top 2 pins of the pot are not connected to anything ?

I would say then that you need to short the lower three terminals together. The way it seems to be wired suggests no risk of the audio being shorted, once those three are linked the control will be innactive and the audio at full volume.

Thats my best guess based on what I can see. It looks like each earpiece is wired via a series connection through each half of the pot and that there is a common ground lead.
