Does the Xbox 360 Wireless Headset Use Bluetooth? No – Proprietary 2.4 GHz

No, the Xbox 360 Wireless Headset does not use Bluetooth technology. It connects via a proprietary 2.4 GHz wireless protocol designed specifically for the Xbox 360 console. The headset pairs directly with the console using a dedicated USB dongle (for the wireless version) or the console's built-in wireless receiver (for later models), not standard Bluetooth stacks.
