Just received mine today, white v1. Using the gray filters at the moment, and unless these things need burn in, I'm not overly impressed. The sound seems a tad on the bright side for my tastes, and a bit lean. I may switch out for the black filters at some point today and see what kind of difference I hear. Also, I can't get a good seal with any of the tips. The comply foam seems to be the best bet, but I prefer silicone tips because of how easy they are to insert. I preferred the isolation of the UE super.fi 4 over these.
So I guess "v1" is actually the second version? I've seen people mention "v2" in this thread as well, so I'm a bit confused....
