I bought a Kotion Each G9000 and it never appears in any place you would devices but the sounds works. The only problem is the microphone. I can't find it and it doesn't work. I use the 3.5mm 4-pin plug that comes with the headset. I'm on Windows 10. All drivers are up to date and nothing requires a reinstall. I have tried most other solutions. Just wondering if anyone knows anything that might help.
