Unfortunately I haven't opened them yet (so I haven't gotten the chance to enjoy them and review them comprhensively at HeadFi as I plan to).
Auditioned them plenty, mainly bought them because they were limited edition. I like the sound signature a lot though. Although I'd say based purely on sound the Shure SRH840 appealed more, but... irrelevant.
On the other hand though I'm thinking of selling them at collectors' price to fund a pair of V-MODA M100s...
...Opening them would mean I get to enjoy them, but then that would affect their resale value!
... Want to open them tomorrow when there's some nice photographic lighting, though.
