“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
“ Like many other people, I got my cx300's as they were widely available on the high street with not much competition at the time. They are mostly known for their bass which is very abundant. The problem with that much emphasis on bass is the rest of the range suffers. Treble, in particular, suffers quite badly and is drowned out. Add to this very little clarity in the bass which doesn't have...” --Marcus_C
“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. Before going into any detail whatsoever about the sound quality or pros or small cons, I'll say this: my pair broke. Not so that they're unlistenable, but I had to fix them up. The...” --NoahZ
“I bought these on ebay.co.uk for £10.99 which is about $18 US or €13. They are a discontinued product, hence the low price, and bought from a retailer called "uk**seller". These are genuine Sennheiser products in sealed retail package, nicely made of good materials and fully up to the usual Sennheiser standards of presentation. goldenears.net has tested the CX 280 (same IEM but with inline...” --julian67
“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. I find myself wanting more crunchy distortion from guitars on metal tracks. But the mids do handle vocals well. The higs sound good to me. Overall very satisfied. ” --ThickT
