Thanks for the link, I looked at it, but my cheap little heart says I can't stomach the sizeable fee (in percentage). I blame the Korean in me. Though I might use it for other purchases I want to sneak pass the little lady.

Got mine yesterday. First impression was bass extends deep, more quantity than IE8 in the sub-bass. I expected them to be muddy out of the box, but surprisingly they have good clarity. However, in terms of instrument separation and soundstage, (out of box) CKS90 acts like a $100ish IEM. They sound congested. Mids and treble is there, however, mids seems a little recessed and 'hollow'.
I never like test tones, especially tones lower than 200Hz. I get uncomfortable whenever I listen to test tones. And listening to music with CKS90 (music, not test tones) I get this uncomfortable feeling...Bass in CKS90 goes really deep, not bloated, but a little 'slow'.
As for the stock tips, just like those come with CK10...Bad for comfort. Never like their stock tips as I get itchy and feeling sore after some 10-20 minutes. The cable reminds me of the little straw which comes with WD40.
Burn in in progress. I hope that soundstage opens up, and instrument separation becomes better after some burn in. Am I enjoying them? Still early to say this, but my e-Q7 easily beats them in sound quality. By the way, I am coming from CK10, e-Q7, IE8, TF10, SM3 :)

It's seems like they are not wide and open sounding like CKS70 but did they improve(soundstage, instrument separation) after burn in?. Please gives us more impression about these new bass heavy IEMs and they looks bigger than CKS70.......
Hi @ZARIM, I have given up on them. After 30 hours of burn in, the sound didn't change significantly to my ears, and I sold them eventually ^^;
Another note, I found that with a deep insertion, bass can become a little bit bloated.
I bought myself a Radius DDM after selling them. The Radius is way better than the CKS90, for my music taste and to my ears.
However, my observation of them is premature, as they could have sounded better after 100 hours or so of burn in.

But the Radius also cost more right? How much is the price difference between those two in Japan?
@koonhua90, I bought the Radius DDM second hand for 9,000yen. I paid 9,000yen for a brand new CKS90LTD (limited red colour version). So to me, they are priced the same ^^
I think the problem is not in the CKS90, but in the Radius. The Radius are too good considering their price, whereas (an approximately 30 hours of burn in of) CKS90 are typical sub $100 IEMs. I don't have much experience with other phones in the sub $100 region, other than some FX66, EX71 and PSP buds.
By the way, the cheapest I can get in Japan: 13,000yen for Radius DDM, 8,000yen for CKS90 (normal black version). In my opinion, the extra 5,000yen for DDM is worth it.
Waiting for first CKS90 review. 
^^^I think you just got it hehe. those look ridiculous!! really a bad turn for what is usually a company that makes beautiful objects. doesnt sound like the SQ makes up for it either.
The dynamic type earphone and ATH-CKS90 of Audio-Technica were bought.
ATH-CK10 is Mid - High range is beautiful!
However, Bass doesn't go out. To supplement this, it bought it.
ATH-CK10 that emits beautiful sound. (You may forget Bass. )
ATH-CKS90 that is strong low region, and makes music happy. 
Red model ATH-CKS90LTD of the limitation first time was anxious, too.
The sound bought the black because it was the same.
In a dynamic type, besides, CKS90 rings because of a bright sound and the sound with a good sea weed though DENON AH-C700 etc. are used.
DENON AH-C700 etc. are used.
CKS90 is a bright sound. It is possible to listen to music happily.
