I have been using AKG headphones since the mid 70's when I started seeing them on the heads of every entertainer in the recording studio environment in film and television.  This said volumes to me about the acceptance by the real professionals. Bought my first pair back then and have had them over the years, occassionally upgrading to newest technology model. I happened to be in the discotheque business back then and I bought AKG's for DJ use in all six of our clubs throughout the country. These are fantastic with full range of natural sound from lows to highs. Does not color the sound and they really kick if you loop them through EQ. Ain't nothin' better. I am so spoiled that sometimes I prefer listening to concert DVD's with these on rather than listening "full room" with my very expensive and well appointed home component audio system. And I occassionally go back to my original set of AKG's purchased in 1976 and they still sound awesome, although the rubber ear pads have become rather hardened and I cant wear them for long. My only complaint about this new pair of "around the ear" phones is that you tend to sweat a bit after wearing them through a movie. I also have a set of fairly recent model 141's that are the "on the ear" smaller pad model with very soft foam pads and I must say that I probably prefer them to the full ear enclosure, for that reason. Other than that, you can't beat the undisputed champ in headphone sound, and at an amazing price point for the quality of the sound.
