Query: Yes, it's all that but the sound is *awful*

Here's the good stuff: great isolation from outside noise, comfortable, damned near excellent bass, and very power efficient. But I'm returning my pair to Tower Records where I just bought them for $15. Why? Because the sound itself is truly awful: compressed, dead, flat, hazy, and tinny (the great bass notwithstanding). These 'phones literally suck the life out of my music, by destroying its dynamics, detail, rhythm, tonal accuracy, and high frequencies, and then layering a harsh fuzziness on top of that. I can't say enough bad things about the actual sound. I suspect you can have a more rewarding musical experience at your dentist's office. I know I did.
