So you'd like to switch between Xbox & PC with your headset. Bold move. Maybe, too bold...
Sike, it totally works on PC. There are two possible ways to do this:
1. If you have the Microsoft Xbox Wireless Adapter for PC, it will sync wirelessly just like an Xbox controller.
2. You can connect your headset via the 3.5mm analog port on your PC (you'd use a 3.5mm male to 3.5mm male cable, not included with the 9X). This will allow you to hear audio, but you will not have microphone compatibility.
Additionally, the 9X is a Bluetooth headset & can connect to any Bluetooth-enabled device.
