Query: Great headphones, only .....

First of all, these are great sounding headphones. 5 stars for audio quality. I have a set of Grado SR-80 andSennheiser HD-555 headphones and the AT's trump both of them in terms of soundstage and articulation.You are right in the middle of the music and every nuance is revealed. The bass is fine with me as its presenceis part of a perfect tonal balance. However, I take one star off because of their size (no doubt a necessary evilresulting in their superior sound) which is rather cumbersome (especially when lying down and using a pillow)and their construction which is prone to emitting slightly audible squeaks and groans (keep your head asimmobile as possible). Well worth living with those slight drawbacks in return for marvelous sound andaffordability.
