“ 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
“ As of 2013, I could only find one pair of these on the internet. It's a shame because from my experience, cheap earbuds are oriented around the muffled bass emphasis and exhausting higher mid ranges. I myself came from the Audio Technica a900x and Bose IE2's which sound darker compared to these $10 earbuds. I love rich vocals and acoustic...” --Nec3
“Bought these locally brand new for $195. For that money they are amazing. I have owned XBA-4, but H3 are much better. Sound quality wise they are comparable to Audio Technica CK100Pro and other top tier iems. Tf10, xba-4, westone 2 is easily inferior to these. But you need burn in H3 and your brain to apreciate H3 sound. There are 2 groups of people - who dislike them and who love them. In...” --kl500

“ The XBA 3s are some of the clearest-sounding in-ears I've ever heard. Granted that list is rather short... but that's neither here nor there! The triple-armature setup is known for providing accuracy rather than "fun" by many, and this is no exception. The trebs and mids are very well-defined and separated, but not overpowering. The bass leaves something to be desired, mostly...” --JoeDoe
“I recently bought these as an upgrade to my Head Direct RE0's. The RE0's are outstanding value for money, and there is not many headphones that can beat it ... until I got my hands on the CK100's. The CK100 packaging box is nice - very simple, and does the job more than adequately. What I noticed on it, which I've not seen in many other headphone boxes is that it lists the product code for...” --s0126471
“ These are most likely the best IEM's you will ever find for trance, let me explain, firstly it is as if they are fine-tuned and sonically crafted for Trance and similiar genres, all the vices you heard in these IEM's in other genres suddenly become virtues and they simply come alive and you are swept away. Secondly, there is something about the sound signature in these IEM's that is trance...” --kiteki

“ CK7 earphone is a nice detailed ear piece with titanium housing which makes it very durable. For me, although i am not using it very often this works the same as it used to be the first day i bought it. They require burn in time at least 100 hours and you can definitely tell the difference in the bass section and the mids. Comfort: i would recommend to be worn...” --FarCry
