my Razer Kitty V2's have stopped connecting to my PC after literally a few days, they aren't even coming up as an unknown device, i bought them on the 3rd of June, and now they’ve stopped working, they've been plugged into the same plug every time I’ve plugged them in too. I don’t know what to do and I just want my headphones to work, the lights aren't coming on, the mic won’t come on, and have no sound, they are literally just turned off, and won’t connect at all.
