Introduction
If the volume control wheel is not rotating properly or adjusting the volume, follow this guide to access and replace the wheel mechanism.

What is the part number of the replacement potentiometer?
What is the part/model number of the potentiometer? I want to replace mine since it’s having issues.
For anyone having static noise or discontinuity when you’re moving the volume wheel, it might be due to oxidation inside the potentiometer.
I managed to fix mine with some electrical contact cleaner (such as DeOxit, I used something available locally though). First make sure your headphones are turned off!
What you can do is, get a cleaner with a fine tip nozzle and point it at the sides of the potentiometer (see step 7 pic 2) that is the joint between the metal and the top plastic. Once that is done, out on the scroll wheel and move it around to make sure the solution spreads. Then take off the scroll wheel again (and keep it somewhere safe!), let everything completely dry up.
Once it’s dry you can put everything back together again, or if there’s some residue on the PCB, you can clean it up using some 90% isopropyl alcohol. Once you make sure that everything is completely dry you can try turning it on again and check if your problem has been fixed.

For anybody who did this, I’m curious about the wheel. From the pictures it seems that the inside of the wheel is some rigid plastic, and it locks onto the potentiometer with those straights sides. The outside of the wheel seems like some kind of rubber enclosing the inner wheel. On my headset, I keep accidentally forcing the wheel when handling the headset, and at one point I turned the wheel ‘up’ beyond its max position. Since I see here that the inner plastic locks onto the potentiometer, I don’t think I managed to turn that (since it would probably break the thing), and instead I turned the outer flexible rubber around the inner rigid plastic. I’m a little apprehensive about this, it really doesn’t inspire high build quality because of this, I’m afraid I can accidentally break it. So what do you guys think about simply setting the potentiometer to the max position, and removing the wheel altogether. Do you think this poses a risk, leaving that wheel hole empty like that?
I was able to follow the instructions and used it to tighten the potentiometer as it was loose. The circuit board is slightly a pain to get out and in.
