Lets say you have a broken headphone plug, this is a way to repair it, by rebuilding it.

What you will need:
Heat shrink tubing / lighter (optional)
Soldering gun and solder
A broken TRS cable (from headphones, etc.)
New cable
Knife
Wire snips or toe nail clippers
Pliers optional

Step 1: Strip the TRS/Headphone Plug

I don't have a photo of doing this but it's not difficult if your good with a knife. Just keep cutting away until the wires and base that the wires are soldered to are exposed. Then un-solder the wires that are there.

Step 2: Prepare Your Wires

Take the wire you plan to use (i'm using cdrom audio cable). Strip the wires, roll the wires (something I do so they stay tight) and tin the tips with solder.

Step 3: Solder on Wires

Slip on the heat shrink tubing (down the wire so it's out of the way) then solder the wires on. Trim excess and make it neat.

Step 4: Finished

Slip the tubing over the the exposed wiring and apply heat equally. This is it, pretty easy huh? I've made a couple of these rather than buying new ones, I prefer to rip them from dead headphones. Freecycling at it's best.
This is a great Instructable, but you need to add a main image of the final project to the intro step. Please do that and leave me a message when you have so that we can publish your work. Thanks!
Updated.
From what I can see here (and what I've gathered from other 'ibles) the yellow wire is the left bud, the white one is the right, and the plain one is the grounding wire. Hopefully that helps. Thanks for the diagram, btw. That helps A LOT--I just realized I've been soldering the ends to the wrong sections of my plug!
Does it not matter if the yellow and white wire are swapped? Sorry if I missed something :-/
All wires do the same thing, as long as you solder them the same at the other end of the wire they will work just fine.
This is what I used as a reference. It doesn't matter which wires you use as long as they match the other tip.
 That was my question too.  How do you know where to solder which wire?
