The SteelSeries Arctis 9X Wireless Gaming Headset is compatible with Windows 11, but with some limitations.

- The headset supports Xbox Wireless Technology, which also works with PCs that have Xbox One Wireless Technology. This means that it can be connected directly to the PC without a dongle if the PC supports the corresponding technology.
- It can also be connected to a Windows 11 PC via Bluetooth, which provides another connection option.

However, it is important to note that the headset may cause some problems when connecting to both platforms (Xbox and PC) at the same time, such as receiving unwanted audio signals from both devices simultaneously.
