Used Razer BlackShark V2 Pro Gaming Headset in ok condition. The battery unfortunately doesn't last more than 30-90 minutes anymore, but they still work well wired with the 3.5mm audio cable. Also one of the earpads is getting a bit detached. I include:
Official Razer box
The headset with mic
3.5mm audio cable
USB C charging cable
Dongle
You can also use them wireless if you keep them connected to a charger
