here is the schematic showing where the wires go. the thick copper is the copper that goes around the rest of the wires. it is not neat like the other wires, but lots of single strands. if you are missing some wires, cut 3 centimeter or so of the lead, the wires missing are probably broken further up the lead.
Getting the solder to wet these wires are notoriously difficult. For me the flux inside the solderingwire was not helping, so i took a match, burned of the lacquer of the end 5mm of each wire, scraped the soot of with a knife, and put flux from a box onto the wire. Then i got the solder to wet the wire. Do this with all the ends of the loose wires. Then solder them to the green board as instructed on the the schematic (it is the top of the two drawings that you want to use).

Be careful not to overheat the PCB. make the solder wet the fire first, then solder the wire to the PCB (green board)

Well the good news is, it's not your ipod.. It's the wiring inside of the headphones. I suggest that you either return them for a new pair, or buy a new pair.

Looking at them from the picture provided by FixYa, I rather think there's no circuitry involved! It looks like the wires go into two speakers. As you don't say what the fault is then I will guess a few things for you and some solutions.
1 One side dead - fault in plug or cable or speaker.
2 Cutting out - faulty cable or plug.
3 No sound - faulty cable or plug.
If you need to get to the speaker, remove the pad, remove foam (force it if it won't come off, glue on when finished). You should see screws then.
You should be able to get a new cable/plug from any good electrical parts shop such as Maplin or RadioShack. You will probably need to contact the maker for a new speaker.

Usually red is right and green is left leaving copper as ground. Click on this link below to watch a video on how to repair a set of headphones

See my tip on replacement of cable and plugs on headphones it help decide what to do.

It rather depends where the break is. If it is one of the single strands, near to the headphones, you might be better replacing the entire cable. If this is the case you will need to remove the foam pads and then you should see access screws to get inside and solder the new leads on.
If lower down in the twin cable part, then you can cut it off before the break and solder a new 3.5mm plug on. The two coloured wires in the cable fit on the small lugs of the plug (you will have to work out which is left or right, by trying them on each lug. The other wires are earths, which fit together on the large metal flange. The T piece part of the large flange grips the black cable, to stop it pulling out. PS make certain you put the plastic body cover of the plug on the wire before soldering on the plug. That you just slide it back on the plug. Make certain the wires on the plug don't touch the earths and also the left and right don't short.
Once you have the plug on, you can buy an extension cable for headphones. This will make it long enough to use.
