I started looking for headphones and listening to them at music stores and later found that I preferred the AKG's sound signature over the others. AKG sounds so silky smooth, neutral/balanced, and even the instruments sound clearly distinct from each other while others just blend into the music. But being that I'm still a newbie, I haven't even heard enough of the really high-end headphones to really get an accurate opinion. I've sort of noticed that even in the high-end, different brands have their own sound signatures. For example, Sennheiser: seems to have something muffled in its sound; Shure and Audio-Technica: has an aggressive sound but still balanced with balanced highs and bass.
Not sure if anyone else has an opinion on AKG's distinct sound signature? Is it something that people here on head-fi either love or hate?
