Moondrop Quark - Best for sleeping, I use them exclusively while I'm camping in the backcountry
Sennheiser IE600 - Daily IEM's, use them mostly while I walk my dog and when I work out
Sennheiser HD800s - Daily headphones, set up at my bedside, use them most evenings
Sennheiser HD6XX - Set up at my desk, I use them occasionally but not very often anymore.
