Just my initial impressions of the DT-990/250 that I picked up on sale yesterday for $139. Opinions seem to be all over the place with regards to highs being horrible, or fantastic. I actually don't find the highs offensive at all, in fact I find them pretty nice and clean. The one song I use to test if I will be able to tolerate the highs is, Fleetwood Mac's "Dreams"(24/96 from HDTracks). The cymbal crash throughout the song can hit my head like a laser on some headphones. With the DT-990 it sounds clean and accurate.
Overall, I like these and they show a ton of stuff that I miss in others headphones. I like my M1060's better, but these are very good. Also, I am surprised that more people don't like these. I will say that they kick arse for gaming.
