I had the same impressions when I first listened to it. The friend that brought them said that maybe I had the known seal issue. These headphones (akg k550) are made for people with really big heads :P . I went to a cart race and couldn't get any helmet smaller than XL on my head, so I am not small headed but these headphones did not stay well on the smallest setting. I don't know what headphones designers AKG has:
My friend said that I should press the headphones a little to increase the seal. The sound changed drasticly, I couldn't believe it. Now I own one :D
After I bought them I applied this mod to them. I enjoy them very much now.
