Things I don't like off the bat: Soundstage seems limited, probably could do with some semi-openness. The higher ends aren't there it doesn't seem as clear.
They are comfortable as fukk, probably the best feeling IEMs I've had. The lower bass is more noticable. Nice to have volume control plus a mic.
I'll keep using them but the Monoprice IEMs I have sound better IMO (albeit a bit sharp on the high end) and are cheaper. They just come out more clear sounding. But DAMN these things are comfy. I'll see if I can burn them in in hopes of sounding better.
