Razer Kaira Pro Distortion/Crackling Xbox X

Hello, I'm trying to help my friend since im a tech. We been having issue with his Kaira pro headset for xbox X (replaced twice)

Tried most possible thing with microsoft support with no luck. They are kinda throwing some random and repeating same useless things like factory reset console, change sound output etc etc..

We need a real answer and I tought it would be best to get it here. We did do the the last firmware, headset is fully charged.

We open a game like Forza horizon 4 on xbox X then we start hearing distortion and bad sound. When its not the sound the headset microphone start to become hypersensitive. Example : When I play with him and he breath I almost hear darth Vader...

I hope you can give some real answer to help or tell us there is a fix for it. At some point my friend is about to return both his Xbox and Headset. I'm trying to convince to not do it, hoping it can be solved.

Thanks
