Xbox Wireless Headset keeps breaking up/disconnecting from Series X

Hi community,

I just bought a new Series X and I've experiencing constant connection loss between the Xbox Wireless Headset and my xbox, sometime, if I'm using the headset it even disconnects the controllers. The controllers work fine when the headset isn't connected, and the headset itself works perfectly on any other device, including my previous Series S where I used to use them.

I've reset my xbox, power cycled, reset the controllers and tried hard resetting the headset too. Nothing seems to be working, is there a fix please? I will most likely be returning my Series X if not.

Thanks!

:)
