If you are talking about the wires from the front panel inside of the pc ...the wire diagram it is present into the manual of the motherboard..and they are numbered and a tab with each one place is present into the manual..of the motherboard (computer ) ..
anyway can use them in the back panel ...cause on the sound card there is a green exit for the headphone the middle..and a pink (red) one ..for the microphone ..and will work just like in the front panel..
or ..if you use the speakers into that back green exit..just plug the headphones into the speaker's headphone out ..and will be even better cause there is a little preamplifier ..and use a separate microphone ..or the microphone from the web cam ...
If you are talking about the jacks from the headphones wire ...just tide them back to the jack s..and to know which one is which ..just make some trials..insert the jack in the sound exit..and after that try to see which ones..(2 of them one colored and one ground..) will make sound in the headphones...Those 2 will be the ones for the headphones..and the other 2 will be the microphone..

    By the way ..if the headphones are ok ..and you are talking about the front panel of the computer being can use both the headphones and the using a 2 input splitter adapter for jack 3.5 this one ..and plug them both ..speakers and headphones in the green in the back ..if you do not have a input for headphones on the speakers...and this way you will be close enough to plug the microphone in the edge pink one..
    here is the adapter Im talking about ..available in all electronics shops and computers shops..

    here you have the front headphone wiring ...scheme.. the cables will get into the places where the jumpers are (the jumpers have the function to connect them when the front headphones panel is not connected..and in your case will not be present if they were connected before..



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

Why is there No sound in bypass mode?

I have found this problem on several PXC 450 headsets and it can be solved by resoldering the bypass switch pins on the circuit board. We use about 25 pairs of these headsets and although they are excellent they can suffer from dry joints mainly on the switch but I have found a surface mount resistor in one case to be the problem.
To get to this board you need to unclip earpad on side containing switch then undo a number of philips head screws to reach the circuit board under the speakers then unscrew circuit board resolder and re assemble. Good luck.

One side of the headphones does not give sound consistently... if I jiggle the connector to the ipod and hold it at a certain angel I can get sound to both headphones, but I'd like to find a real...

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.

Headphone wire cut can it be spliced back together sennheiser pxc

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.

Hi, could you please provides a circuitry diagram for PXC250.My headPhone was broken, i'm gonna to fix it.cheers!

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.

Replacement connector for Sennheiser PX 250 doesn't work...

The bare copper conductor wire is the screening/common earth to the two signal wires of green and red. The important connection is the copper wire which goes to the jack plug earth which is the section furthest from the tip. The other two are the left and right signal connections. If you get these the wrong way round you will just have to swap them over. Check if they are the right way round by using the balance control on your amplifier or whatever. Have you checked that the problem is not with the headphone amplifier within your equipment? Don't rely on OK sound from loudspeakers as the headphones may be fed from separate op-amp output chip. Try another pair of cheap and cheerful headphones to make sure.

Replacing headphone connector

The impedance or resistance of the two different sets of wires might be different. The higher the impedance the less signal. If your cable is long enough you are better off spending the five or so dollars for a new plug. Red is right, green or blue is left and copper is ground.( Usually) Unfortunately not all manufacturers agree. Also what could have happened is a short between the wires that you soldered.Make sure they are physically separated from each other and insulated.

Replacing headphone connector

My jack plug lead got yanked and broke the wires inside the electronics unit. There are three screws to undo in order to get inside the electronics, one by the cable entry and two very small cross head scvrews in deep holes halfway along the unit. I cut the jack lead on the outside close to the cable entry and drilled out the hole through the cable guide and then poked the jack cable back through the hole into the electronic unit. I was able to solder the three leads to their respective pads. There are five solder pads next to the cable entry. With the cable entry at the top, the middle pad connects to the green cable, the rightmost pad connects to the red cable and the copper connects to a pad about 1 cm down from the rightmost connector. The technique was to tin the ends of the leads with solder before soldering them to the pads. I used a blob of glue from a glue gun to hold the cable in place inside the electronics unit. My plan B if the soldering was not possible was to take a jack plug and lead from an unused set of earpieces and use that lead in place of the original. It would have been much more difficult to replace the lead from the electronics unit to the headset.
