Hi Carl,
Okay so this does seem a little more technical, I can manage a little as am a Noob to Electronics but from what you are saying I think it is best I provide these images for guidance.

Please refer to attached images, apologies if they are not the clearest, however I hope you can see where I am referring.

- image (TRRS jack) you can just about see the white (MIC) wire is connect the the Sleeve, however the other wire attached I cant work out because it is moulded in with the black plastic.

- image (Single earbud) you can just work out that the wires used are solid Red, and solid Copper.

- image (Front of PCB Mic slide switch) you can see the slide switch and the Mic.

- image (Back of PCB Mic slide switch) you can just work out the wires as I previously mentioned above and the 3 SMD components used.
Again apologies for the images and possible lack of information, had a realised this was going to be a mission then I may have just binned in, but since I have it apart (using my ESD wrist strap and mat) I feel I need to complete this repair and give myself a pat on the back hahaha
And of course will give my appreciation and approval to you
