ayi your headset has a combined jack (four contacts) for microphone and headphones, while your PC has two separate sockets (three contacts each) for microphone (pink) and headphones (green). either get a headset with two separate 3-contact jacks or get an adapter with one 4-contact socket on one end and two 3-contact jacks on the other end, like the one in the picture https://preview.redd.it/pk5gz2djis5g1.png?width=600&format=png&auto=webp&s=061e9f0ff664cf68abfadfc16bac9cac669e0926
