They are good, for me they are a keeper where you need a closed back headphone. I like the emphasis they give to mids and bass. Still need some break in time for the upper registers (when compared to my everyday can's HD-650's). This may be just because I normally listen to open back cans, we'll see. I plan on giving these a good month before deciding to "gift" them to a son or not. I was surprised at how good they isolate you from other noise. My wife is listening to a bad copy of South Pacific now and I would know it if I didn't have to turn on the amp for her.
My can collection: SENN- 150, 598, 650 Grado 225i, a pair of Beats, Beyerdy DT 770. I prefer open back now but these will stay connected to my Crack w/SB in my bedroom. The only complaint would be that I have a big head and big ears, these aren't as comfortable as the DT770 for extended listening.
