As far as I know it's the younger brother to the HD565/545/535, which were all said to have a similar sound. I have the HD545, which has a laid back sound similar to HD580, but with slightly less details, clarity, and bass. I've been led to believe the HD535 and HD525 would sound similar to my HD545. All these are quite comfortable and great for computer and tv use, although the HD545/565 have velour on the earpads rather than pleather. I prefer the HD5x5 sound to the Grado Prestige series, but tastes differ of course.
