Hello everyone,
So the headset isn't mine but my cousin's and I took the liberty to try and fix it for him since he doesn't have much knowledge in these aspects.

I've had a bit of experience with wire management and soldering since I've had my own headset to fix, which is actually a jack plug not usb. As far as I can remember, it had 4 wires. (Left, Right, Ground, and Mic) and it also had a volume controller with mice mute and unmute but I figured it was the one causing me issues so I took it off. In the end, I managed to fix it.

While in this case, to my surprise, this USB headset had more wires and I've no idea what to do with them. The cable that's coming out of the headset left ear has 6 wires that in the end is connected to the volume controller, on the other side (the cable coming out of the USB plug) has 5 wires.

Here comes the shots:
Onto the controller:
Lastly:

Well, I'd be grateful if you could point out the exact locations where to solder each certain wire. Actually I can discard this volume controller and use an external one. Thing is, I tried wrapping the end of each wire and see if it works but no good.

Usually when you plug in a USB powered headset it automatically sets as the default sound player, but the sound was still coming out of my speakers whenever I plugged it in.

Any help would be greatly appreciated. Thanks!

P.S read my reply down below

You cannot (easily) bypass the controller since it takes care of converting analog audio (microphone and headphones) into digital USB standard.

The USB has four wires: Ground, Power, Data Plus, Data Minus, plus shield. You can check the connector' side pinout from eg here, and ring the wires. Your initial goal would be to plug the cable (with controller soldered), and make it register in Windows' Device Manager.

I see, so I can't help it but re-solder the wires to the controller. I'm starting to have a much better idea about how this works. Explains the weird abbreviations that I didn't get at first (GND, DP, DM, etc..)
Strangely though, the wires that were originally soldered didn't match the standard pinout in that wikipedia link. You can look at the 2nd picture to see how it is, although I doubt you can tell from the quality so here is how it goes:
-Gold to GND
-Red with Gold to GNDA
-Blue to DM
-Green to DP
-Red to VCC

Alright so the USB pinouts aside, I can just resolder them the way they originally were since I already took a picture and know exactly where each color goes, but the main issue is in the other part (supposedly the Left ear, Right ear, Mic, and ground) <- that's 4, but I got 6 wires
They are:
-Blue
-Blue with Gold
-Green
-Green with Gold
-Red
-Red wrapped in white (I'm assuming this is for mic) see the first pic

And as you can see on the controller right side there's 6 soldering areas (disregarding the last 2 which I assume are for led)
The first one was originally soldered with a gold wire that stayed in place after the rest were forcefully snapped, the last one is a red wire that I soldered after testing but forgot to snap it for the picture.

So the question is, where does each wire go? And why the hell was there a Gold wire soldered to the Mic Ground pin? When I cut the cable shorter there was no Gold wire as thick as that, only the ones I listed above. Unless.. You deattach the Gold wire from each Blue and Green? but that wouldn't make sense. (at least for me)

@Abbyfa,

Upping / pumping / bunping won't help in getting an answer. If someone could add something to what has already been said, it would be done.

You still did not provide info how far you've proceeded. Attach the USB cable, and check whether the controller is recognizable. Once you do that, you can start probing other pads on the controller (eg with spare mono headphone, playing one channel at a time).

I guess you're right. I'll try to experiment with it myself and see how it goes. Sorry and thanks, Alabalcho!
