I just got these for christmas:
I haven't spent a ton of time on them yet, obviously, but first impressions are really good. I will be using them for Dj Monitoring and a little studio monitoring as well. It has a mono/stereo switch on one of the earphones which is nice so you can run it mono for 1 ear monitoring. The bass is a tad weak compared to the high end, but it doesn't bother me at all. Blocks out outside noise quite well and doesn't leak out much at all.
Only small complaint is about comfort. There is a tad less padding on the head band than I would like, but still plenty comfortable for hours of use.
They are $86 on Amazon down from $150 so that is a pretty good deal. Anyway, hope that helps!
As mentioned above, grado sounds absolutely incredible, however, I don't like the open ear design for every day use.
