Just loose very early impressions:
I'm lucky. The fit is excellent, and they're extremely comfortable. I'm really not much into having things stuffed in my ears at all, but I've had them in my ears since 3:30 today, and am only now starting to feel a little claustrophobic.
I was a bit of a pita re color and art. I wanted a very pale rose (NOT pink) with the M&P toting kitty in my avatar. It came out exactly as I'd hoped. There are a few very small bubbles in the right earpiece, but so minor as to not bother me one bit, and the left one is perfect. I was a bit worried about both color and art, and Adam nailed it.
I've been just messing around, listening to a little bit of everything all for fun, and not listening critically at all. Live shows sound like live shows. Studio recordings sound as they are. Love the sense of space and instrument placement. Yes, you do get a sense of soundstage. Detail is superb, but not at the expense of body. Tone is dead-on, as far as what I'm picking up on this early. Drums and bass don't get muddied up together. Real decay (wasn't expecting that). Etc. Very loose first-shot things I'm noticing with either a old nano (don't even know what generation, but at least two or three more have come out since) and no amp, or a pico and my laptop.
I did have my first OMG moment, with the first track on Gilad Atzman's Exile where it starts in with the low bowed bass, and then Reem Kalani's powerful voice just knocks a hole in the middle of your chest. Had a very visceral, powerful reaction, almost like one of those horrible adrenaline rush-and-drops that happens right after avoiding an accident at 80 miles an hour. It wasn't pleasant, but the song wasn't meant to be pleasant. Very cool these little iems just put it right there.
I'm very very happy.
