“ 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
“ 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.

I had bought them from Sweetwater and they replaced both of them...” --Lifter59
“Bass response doesn't bleed to the vocals or any other frequencies whatsoever, lightweight cable with no microphonics and a narrow plug to connect to portable devices.

“ Disclaimer I bought these about 3 years ago, used them a lot and got to "know" them well. The (sort of a) good thing is: They still perform as good as they did when I first tried them on.
