Input:
I work for an IT music company.  We listen to a LOT of music.  I'm not a crazy technical person about the specifics of tone, but I can hear the difference in quality.  These are great headphones.  My coworkers borrow my headphones and are astounded.  I keep several pair and replace them as they break (Their breaking is no signal of their worth, but a signal of my terrible coordination with a vacuum and dangling headphones cords...)

Great headphones that I'd suggest to anyone.
