I just tested on xbox one.

- Voice chat does not work with this device.
- The Sound Blaster X G5 is only compatible for game sound via the supplied optical cable. But I notice that the sound is less amplified than connecting directly to the controller (even with the volume turned up).
- The Sound Blaster X G5 is not compatible with the 7.1 audio format, but it does have a basic format that simulates 3D sound.

To sum up, according to my test, I would not recommend it for use on xbox one. Because it is not fully compatible. On the other hand on PC and PS4, it works fine.

I use it, mainly, on PC and PS4 with a Sennheiser Game Zero headset. I can guarantee that it works great on both platforms.

I will test it on my xbox one if it is compatible and I will send you my test as soon as possible.
