I got my X1's about two weeks ago. I come from an HD 598's, and I find the X1's to have a smoother sound, a bit darker, so less soundstage, less comfortable due to headband pressure and heavier weight. However, it has a much better low end which is really enjoyable.
I used two pieces of cloth from an old t-shirt to tie up the headband and reduce the down force on my head (if this makes any sense).
The comfort has really improved a lot.
