I was given a fantastic pair of KOSS Studio-grade headphones. These things are amazing. You really have to be dedicated to travel with them as they're a bit bulky. But the sound is amazing. I was listening to some digitally re-mastered Louis Armstrong tracks. Granted, it was a tremendous digital remastering job, but listening to them with the KOSS headphones I heard Satchmo's lips smacking during some of his vocals. Oh wait, when we're talking about Louis, they're "Chops" not lips
