Razer Kaira Pro Problems

Hi all, So I've recieved a new Kaira Pro in the post today - but had nothing but problems with it! My first one is the firmware update - the software keeps on freezing on the 'plug in your headset' page - the PC recognises the headset every time you plug it in, but you can never click the update button, and the tab just goes funny every time I try, so just have to kill it and restart - I have not managed to update the firmware as of yet. I now have it connected to an Xbox One S, and in party chat there is a constant white noise in the background that I cannot get rid of. There is also a occasional loud echo for everyone else in the party coming from my headset. I also had struggled with the Razer Headphone App on Xbox, which struggled to see the headset. I since got this working after re-connecting multiple times. Doesn't seem great for what is sold as a new flashy headset! Anyone have any ideas, if not I'll probably return it in a couple days
