If 7.1 isn't necessary and you already have a mic, I would suggest you take a peek at just normal audiophile headphones. If you don't mind Reddit, some good pointers and ideas in this thread https://www.reddit.com/r/HeadphoneAdvice/comments/yobt7y/has_anyone_used_audiophile_headphones_for_gaming/.
I've been using Beyerdynamic DT880 pro for a few years and they're amazing. Comfortable as hell and pads can be removed easily and cleaned or swapped. Great sound, zero regrets with these headphones. The entire DT lineup from them is very good as far as I know. Another go-to option is Sennheiser's 600 series, but they're a bit more expensive. There are numerous others but those are the ones that I know of.
I would suggest browsing what the /r/HeadphoneAdvice has to say, asking about audiophile headphones for gaming is a common question.
Also all the artists that made comics from posts and responded with only pictures. There were few of them and they were always amazing.
And Andromeda321 for anything space.
And poem for your sprog.
And probably many others!
Good times.
