If this is a USB one, get a new USB cable. If it’s a '''HEADPHONE''' and '''MIC''' connector, get one of those. To open up the headset, turn the ear cover on the left towards you. Simply unscrew the tiny screws at the bottom and under the sticker. When you get in there, un-saughter the cable. Now, saughter the new cable. Sometimes, this works successfully, sometimes it doesn’t. If it doesnt, try re-saughtering some stuff and make sure the cable isn’t bad (that you ordered). Hopefully this helps!
Hoping I didn’t type this after you fixed/bought it.
