Reporting back: I ended up buying the SteelSeries Nova 5X. I was gonna buy the Nova 7, but surprisingly the mic quality on the Nova 7 sucks ass. I found some videos where the reviewer showed the mic quality on the 7 vs 5 and the 5 sounded way better.
This seems pretty well supported by headsetcontrol.
