I've heard these on numerous occasions and while I wasn't blown away I wasn't repulsed either. I just prefer my Focal Spirit Classics (which sound kind of similar) and my HD6XX.
I actually liked the looks of these headphones, but the adjusting mechanism on them is a bit weird and it definitely takes some getting used to.
