I'm just going to throw in a FYI into the mix regarding sim audio and networked P2A install audio.
This is now entirely possible in the same headset these days. I have the Arctis 9's and they support simultaneous bluetooth and wireless receiver input from different sources and voice output to different sources (there are other headsets that do this now too). I have bluetooth turned on in the laptop and wireless headset dongle plugged into PC and this works perfectly. Just thought I'd share that in case anyone wants to do likewise without the hassle of software or additional hardware such as mini mixing desks etc. Hope it helps someone.
