Okay, got my DT250-250 and I am absolutely blown away. I honestly didn't think this type of sound was available in closed cans. The treble is a little more rolled off than would be ideal for me, but that is really nitpicking. The bass is excellent. Goes deep and is very tight, but still provides some rumble when called upon. The mids are amazing. I am very particular about vocals and these are excellent. Surprisingly they have just good enough volume and sound quality out of my iPhone4S, so that takes care of my occasional portable needs. Did I mention I am blown away? I have been A/B'ing with my HD580 (600 grills) and I am having a hard time choosing. Just when I think I found a flaw in the DT250, I switch to the 580 and the same flaw is there. The 580 has a bit more treble presence and air and a hair less boxy in the mids. I am still in the honeymoon phase, but the 580 might be on it's way out.
I feel very sorry for everyone looking for a neutral, mid-centric can who hasn't tried these. A lot of people are missing out on the best closed headphone I have come across. I am so glad I found this thread.
I have only shortly tried a friends HD600 and felt a kind of "clamp effect" not very comfortable
If I exclude the Senn's what does people find to be the best open headphone to compare if I like the DT250/250 (which I expect to do, just ordered) as my K701 does not really make me spin records
