“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
“ 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
“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
“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

“ These are decent IEMs. One way to describe them is 'exceedingly average'. There's absolutely nothing special about them. Nothing that's so downright bad, but nothing that's really great either. They don't sound fantastic in any way. The soundstage is a bit too small for me, and the bass is rather pushy. Maybe one more thing that's worth mentioning is that they're...” --National
“ I bought my pair of cx400 to replace my cx300 and was expecting it to be a more refined version. I was, it's pretty safe to say, disappointed. The sound you get from these is far too similar to the 300's for their own good. I had the same problems with the cx400 as the 300. So I got boomy bass which drowns out the rest of the range.In this day and age I can't think of one good reason why you...” --Marcus_C
“ After my CX300II's broke it became a frantic search of a replacement that'll provide me the same kind of quality and bass that I loved from my previous pair. I ended up deciding between antoher pair and the Sennheiser IE60. I havent regretted my choice. Setup: I used my COWON J3 with no amp. I use a custom equalizer (found here on head-fi). The music I listen to is pretty...” --Luchico638
