Saw these in BB today and decided to have a listen (I wasn't shopping for headphones, but it was hard to resist!). I'm pretty sure these are the first Beats I've ever listened to. I only spent about 5 (extremely enjoyable) minutes with these and I was thoroughly impressed! The build quality seemed excellent. They are very elegant and masculine looking at the same time. They were VERY comfortable (albeit for 5 mins). I found the sound to be excellent! The sound was so powerful, with very tight bass, not a hint of boominess. The mids and highs were well represented, and to my ears the output was very pleasantly balanced. I'm thinking that these display cans are probably hooked up to an amplifier since I doubt a phone or mp3 player could put out such powerful sound. Perhaps they wouldn't be so impressive with my ZuneHD or LG Motion phone, but for about 5 mins I was a believer!
