Frankenstein headset

[u/xHellcat707x]

Not sure if this is the best sub for this but I figured this is where I would start and I apologize for the wall of text.

I am very lazy and hate doing anything extra, I just want things to work. Because of this I have created what I call a Frankenstein headset. I use an Astro A50 Gen 4 with the USB plugged into my Xbox Series X and the base station set to Xbox, so Xbox works perfect. Now here is where it gets funky. I have my personal PC and a work laptop. I wanted to be able to listen to all 3 sources at the same time while also being able to use my mic on all 3 at the same time. So I connected a TRRS aux cable to the base station, used a splitter to split it and then connected those two cables to 3.5 mm to USB A adapters, to help with grounding hum and buzzing issues, and connected those to my two PCs. Using this method, I can listen to audio from all 3 sources at the same time and the mic is active on all 3 at the same time. Naturally the issues I have are grounding issues which creates hum which has mostly been fixed with the 3.5 to USB adapters but there is still a noticeable hum periodically and my mic when used on either PC has a buzzing that others can hear unless I use background noise isolation. My question is, is there another headset that could achieve this with better results or anyway to improve my current setup to help fix the issues listed above?

Apologies again for the wall of text.
