Questions about FiiO K11 R2R

The FiiO K11 R2R is unlikely to work with the Xbox Series X, especially when it comes to using it as an external DAC via USB. - The Xbox Series X does not support external DACs over USB as it does not have drivers for such devices. Unlike Windows systems, where many DACs are automatically recognised and supported, there is no way to install custom drivers on the Xbox Series X. - There is no official confirmation from Microsoft that the Xbox Series X supports external USB DACs such as the FiiO K11 R2R. Support for USB audio is limited to certain licensed headsets and not aimed at general DAC devices.

The FiiO K11 R2R is primarily designed for use with PCs and the PlayStation 5, but there is no specific support or compatibility with the Xbox Series X mentioned. - The devices support USB connectivity and different audio classes (UAC 1 and UAC 2), but these functions are mainly optimised for PC and PS5. - There are no official specifications or tests that confirm compatibility with the Xbox Series X. It is therefore unlikely that the K11 R2R will work with the Xbox Series X without further customisation or special configurations.

According to our research, the FiiO K11 is not officially compatible with the Xbox Series X.
