My Headphone's microphone sound muffled and hard to understand

I have a pair of Corsair Voids (A USB headset), the microphone has been good up until this point. It was fine one day and when I woke up the next the microphone sounded terrible.

Fix Attempt 1

I assumed it was maybe a faulty port or something, so I switched and swapped around ports but to no avail. The microphone still sounded terrible or just didn't work at all.

Fix Attempt 2

Next, I tried to update every driver through device manager, and I thought I struck gold when Communications Port 1 "couldn't start on boot", so I disabled it then re-enabled it and it worked fine, but my microphone sounded the same. It was after this that the microphone stopped working all-together

Fix Attempt 3

I reset my computer so that there was nothing on my hard drive except for my OS (Windows 10). The microphone however, started to make sound again! Although it was still the same distorted, muffled sound from before.

Fix Attempt 4

I tried searching for answers as to why this could be happening, but I kept getting the same answers:

"Disable audio effects" - This was never an option for me as for some reason I don't have that option.

And

"Clean out the dust from the microphone itself and the port" - this wouldn't make sense, if a build-up of dust made my microphone start working, why would the quality deteriorate overnight? Also, I HAVE tried using every single USB port on my rear I/O and the two on the front of my case.

Fix Attempt 5

More of a temporary solution, was to use my mobile earphones and use them as a line-in microphone, but these did not record audio at all (I tried both the front and rear ports).
So I resorted to using Discord Mobile, with my ear phones plugged into my phone, in my ears and my headset over my earphones, over my ears. The problem is with this setup is that my earphone's microphone ALSO has stopped working. What an unfortunate coincidence

Fix attempt 6

I tried using many different voice-changing software (Voxal, Adobe Audition, etc.) although I could do nothing to improve the quality of my microphone.

Fix Attempt 7

Here I am! Asking the same place I got my previous solution from. What the hell is wrong with my microphone and can I fix it, and how?

I am happy to provide any other information or media that you need to help me figure out my problem, thanks for your time!

UPDATE 1:

I tried using my mic on a different computer (my mother's Lenovo laptop), they sounded fine - they sounded like they always do. Vocaroo Sample

Although, they still don't work on my PC.
