Help Repairing Headphones - What do these solder points mean?

Hi Everyone! I am trying to repair a Turtle Beach Recon 200 headset. The 3.5mm plug was destroyed, so I'm trying to replace the entire cable/wire that was soldered to the headset's circuit board. I am comfortable with basic soldering, and anyway, I'm doing this mostly as a learning experience. I already took the earpiece apart and removed the old wire.

First off, I'm not totally sure which replacement cable I should buy. In doing some research, I think a four-pole connecter will work, like this one…. is that correct?

But where I’m mostly stuck is figuring out exactly how to solder something like that back to the circuit board. Based on how the old cable was hooked up, it seems like there are 5 wires… but if the new cable on has four wires, which solder point can be ignored? Does anyone know what the acronyms on the circuit board mean by the solder points? (eg MP, MN, LN, LP, RN, RP). There was nothing ever soldered to the LN point (you can see that in the “before” pic).

I would be really thankful for any help/recommendations people have! I’ve included some pictures of the circuit board before and after the damaged cable was removed.

Thanks!!

This is a standard wiring configuration

LN, LP, RN, RP == L-, L+, R-, R+

LN and RN are common which is why there is no wire on LN. MN is also connected to RN at the plug.

MP, MN == M+, M-

you might find something you can use here.

Thanks so much for the great information! I ended up buying this one:

Now I have to wait a month for it to get here before I can even try and solder it.... If it doesn't work, it was only $2 shipped, so no big loss. Thanks again!

I actually got these repaired, and they're working again!! The cable I linked to in my other comment ended up working. The biggest challenge I ran into is that the colors of the wires were not consistent with any wiring diagrams I saw online, and the cable didn’t come with a pinout diagram. So I used a multimeter continuity check to figure out which ‘segment’ of the headphone jack plug corresponded to which wire at the end of the cable. (eg; Green wire = first segment; Blue wire = second segment, etc)

From there, I used the plug diagram in @ruggb ‘s answer to figure how to solder each wire back to the circuit board of the headphones. (eg; first segment = Left Audio ; so solder Green wire to "LP"). And it totally worked!!

Thanks again! Cost me $3 to fix a $50 (retail) pair of headphones.
