I recently bought these at radio shack and when I first got them they didn't sound like what everyone said they sounded like. They actually sounded disappointing compared to my standards. However when I burned them in for 2 days and used them frequently, the sound really opened up and everything just got better. I am now a believer in burning in headphones.
For those who wish to know about the sound (at least in my case) The bass was extremely bloated first of all and it was awfull because it bled into the other frequency ranges which was the main reason that it ruined it for me. The second was that the soundstage wasnt very good. Also all the ranges of the headphone seemed loose and out of control especially the low range. However after burn in, BAM right there was a new amazing pair of headphones with tight punchy bass nice foward mids and beautiful highs
