Summary: I have only just started using the headphones a few days ago but I really recommend them. The sound quality has been excellent out of the box, as I am still wearing them in, but so far very impressive.
Pros: High and detailed sound quality, Large soundstage, Good bass, Comfortable open headphones
Cons: Quite strong treble for some people, slight issues with build
Summary: I reviewed the 32 ohm version of the DT990 Premium Open headphones and I have to tell you it was a joy.

Summary: Last year I bought Beyerdynamics DT990 Premium with 250 Ohm in a custom design:
I really love their design (Of cause, I also designed them in some way :p)!
The opportunity to create your own, unique style for these high end cans is pretty cool.
