No Grados here in poland but I own a pair of Senn 485's and can recommend them.
They are rather extreme, ie they really emphasize both bass and treble BUT mids are present and every frequency is clear, defined and not distorted. They are really alive and exciting, they sound really good, precise and they bring out details I never heard before.
Soundstage is appreciable, you feel surrounded by the instruments, like sitting AT the drum set.
IMO they are amazing, especially considering that you get a padded holder to clip on a shelf or a table, very convenient. I like they way they look too (Grados look Eighties...bleh)
Comfort-wise they are fullsize cans but the earcups are not as big as other Senns (ex HD555 or HD595) so you definitely feel the foam resting around your ears.
I suppose this detail and they fact that they sound all but relaxing (but WOW!) makes them a bit uncomfortable over long periods of time. Having said that I spend many a night watching movies and TV shows in a row without any problems and I don't have small ears.
PS they are very light and solid, the plastic they use is top notch. Do not bend the headband too much though, it is flexible and will conform to your head but don't play too much with it lest it snaps.
