Why is my Apple Earbuds microphone not working with my audio splitter on my gaming PC?

I have a gaming pc with the usual 6 audio jacks. I was using a pair of Apple 3.5mm 4 pin earbuds with Ducabell audio splitter because the microphone wouldn't work otherwise.

The audio and microphone both work but I decided to order a new pair as this old one was having audio issues with the right earbud (the sound was very quiet).

However. The microphone on this new earbud doesn't work and instead makes a thumping steady noise when I try to use the mic.

I remember this was a problem before with the old pair but I can't remember how I fixed it. I have already gone through all the typical steps of checking if it is the default device, uninstalling drivers and restarting, etc.

The old pair's microphone works fine when I plug it in but the new one doesn't work at all. They are the same exact pair. i am using windows 10

Thanks you
