In defence of the absolutely clear plastic shells: you get to see EVERYTHING inside from the new 10 step low pass filter to the branded drivers to the ligatures holding them in place. It looks cool. That said, it really does look a bit like a hearing aid. I'll admit that. But, in the right light (and Shure Japan photographed it in the right light) it looks amazing!
As for impressions, I'm working on collating them right now and will update as they are on paper (not real paper, but something that looks like it but doesn't burn).
