I just bought some DT880s yesterday while waiting for these to come out. I think I prefer the clarity and signature of the Beyers, but it's too early to tell. Compared to my HD280s though, they sound fantastic. Maybe I'll pick up a pair of these in a month and see which one I prefer. I certainly like the looks of the MOMENTUM more.
Hey yokken... Did you end up buying a pair of the Momentum's in the end? How do they compare to the DT880s?
