The headsets are completely identical, save for the colors! Whether you’re getting the PS4, the Xbox, PC, Call of Duty, or the new Legend of Zelda version, it’s the same exact cable, and the same exact headset.
Not sure why folks are having reversed sounds on Xbox in Fortnite, hadn’t heard that before! But I guarantee it’s some sort of other issue and not the headset. Both the Xbox controller and the PS4 controller use the same pin configuration for their audio outputs.
