“ 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
“ 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

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
“ I first purchased these because I wanted something good to use. Everyday travelling to and from school/work would take me about 3 hours (round trip); so having good quality IEMs that isolated me from the noisy bus and other distractions was something I wanted to have. I saw these in-store and thought I might as well try them. I've heard of Sennheiser before but was the quality as good as its...” --Luchico638
“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
