“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
“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 don't have any headphones to compare them to, as these are some of my first good quality headphones. They sound great, they're pretty comfortable, if you wear them around the house, or just walking around, they stay nicely in your ear, however if you do something that makes you sweat, they don't stay in your ear well. I'm guessing this can be fixed with custom tips, but I never bought any....” --RyanDN
“ CKS line improves the main problem of traditional audio technica products which was bass. CKS50 did not focus on the quantity but the quality of bass, it does not have the quantity for hard rock music but it was tight and powerful enough for pop-rock also it still have the sweet mids like audio technica do which makes my perfect choice for j-pop female vocal.” --Kiln
“The build quality of these earphones are perfect: from the very first time you hold a pair of these in your hands you know that they won't fall apart any time soon. But this build quality leads to some issues: the housing is pretty heavy and this can make the use of these clip-on styled headphones pretty uncomfortable for some people. Noise canceling isn't really good but keep in mind that this...” --Maniello
“ Comfort & Fit First thing to note, these earphones use balanced armature drivers rather than dynamic. Because of this getting a good seal is critical for the sound. Without a proper seal they sound tinny with no bass. Straight out of the box the fit is awkward as you have to sit there fiddling with the memory wire that sits around the ear so that it sits firmly....” --dogroll
“This IEM is vocal oriented and so they are especially for vocal lovers. It is clean, detailed and upfront. This is not a basshead IEM instead it is punchy, detailed maybe a little slow on some really fast tracks but generally it is quite involving and fast. There is no midbass bloat I could hear so there is no veil in the mids. The guitars especially sound amazing on these...” --ozkan
“The IE800 are the best IEMs I have ever tried. This includes the Shure SE846 & 535, Audeo PFE232, AKG 3003, JH13 and JH16 and many others. I also prefer their sound to many full size cans like the beyerdynamic DT-880, T70, T90; Sennheiser Momentum, HD650; Shure SRH1840 etc. The closest I've heard to the amazingly balanced sound of the IE800 is the LCD-2 rev 2, which I also own. The...” --scoyig
