Technical/production listening and recreational listening. When I close my eyes, I forget I'm at my desk and I think I'm in my little studio behind my KH310s, and that's saying something. These will be for critical and recreational listening at another site. I learned stuff about Norah Jone's breathing technique :_) because you hear absolutely everything.. Possible con for some of you is that you need the app to properly set these up and the time-of-flight-based setting is critical, for spatial information, so it may take a few tries and precision to get right, at one sweet spot, so don't mistake these for hifi speakers. Otherwise 10/10. Unbeatable at that size or price point.
