Well, I don't intend to make this into a review thread so general discussion is more than welcome.
I've just taken a nap in the RE-ZEROs with some of my favorite vocal albums (Vienna Teng, Regina Spektor, etc) and I am far more impressed with improvements in soundstaging and positioning than the low end (I expected the opposite). The ZEROs do a great job of portraying intimacy but they can also simulate distances fairly well. Not as well as the Phiaton PS200 and Senn IE8 that I've been using lately, but definitely better than the average mid/high-end earphone (which I couldn't say about the RE0). Still great clarity and detail for the money and absolutely no harshness to my ears (<10 hours on them still).
