“These are normally over $400 on Amazon, where I got them for $100 "opened, but unused" with high expectations corresponding to the $400 price. They had all the tips, but with two mounted on the 'phones and four in the case; no grill cleaner. The problem I found, but which bothers me a lot, is that the highest notes on one of my favorite recordings, Philip Glass's Mishima soundtrack (which is...” --akgK340owner
“ Upgraded from my CX-215's WHICH ARE ALSO AMAZING! But these kill it in audio replication. I use these at work with my Sanza Fuze (Rockboxed and playing flac's) and it makes the day's fly by, My only complaint was at first finding the proper seal took a little work, also seemed to have a slight burn in period (which wasnt to bad) but when i first purchased the headphones I was...” --darkshyed
“PROS - great sounding headphone - great in-ear fit - good quality cable - unobtrusive design CONS - slightly heavy bass for me NOTES Equal length cable for each ear (not for wearing behind the neck) ” --gingerbeardman
“ This past summer I was looking to upgrade from my mediocre Sony behind-the-neck on ear headphones. I wanted to stick with open design and behind the neck, and these seemed to fit the bill nicely.

“I am going to keep this short. SOURCE: Cowon C2 320 Kbps Mp3 and Flac files. GOOD: - Fits my ear properly. I am sure, whatever i do, they won't fall off. - Isolation, is good. BAD: - I feel that based on the shape of ear canals this could turn out to be a nightmare for a few people to wear. - Just a flimsy pouch and three tips -...” --wrathzombie
“IN MY OPINION!! The bass on these completely blew me away. Pounding. Hard hitting without loosing much detail. By far the greatest aspect of these buds. The mids are not as forward as i would like.
