I've got mine from
https://www.amazon.co.jp, new, just under $90 including DHL delivery that took about a week.
CH9T are the most detailed and precise, transparent and clean sounding ear/headphones I have ever owned.
These are very balanced (albeit leaning towarsd V-shape), frequency response appears to be flat, I cannot identify any frequencies that are lacking or over-represented.
Soundstage is realistic, neither narrow or wide, but high frequencies (both amplitude and precision, detail) help to create very convincing 3D spacial illusion, especially on the reverb tails that sound like they extend from you ad infinitum, sometimes even wrapping around behind (or rather creating such an illusion), especially when using "gradual" filer on my M2s.
Despite being analytical due to the precision and low-level detail reproduction (even leaning towards being clinical and somewhat dry) I feel they are very musical or rather they are not getting in the way between music piece and listener. Having said that their level of detail and transparency makes them rather unforgiving towards any quality-related issues in the music itself, unlike with some earphones that smack and smear their sonic signature all over the frequency range thus bringing any and every musical piece to the common denominator of their "signature" sound ( I can think of few examples here).
Fit is very comfortable and stable, they are quite light and their shape and size helps to set them right supported by outer ear shape.
Tips are wide-bore and have fins inside that help to lock earphones in the ear canal, but since CH9T are wide-bore I get best fit with smalle size (although I normally use mediums). They respond to tips rolling well, but I returned to original small size tips eventually, as they work best when inserted deeply in the ear canal, so that they come into full contact with parts of outer ear, helps with sound quality and secure fit. Update: ended up using rather tight fitting (both on nozzle and in ear canal mediums, not stock).
CH9T's are the first pair of earphones that are all but not source-dependent, retaining their characteristics (or rather - the lack of them) between different sources: I tried Zishan family, Shanling M2s, MacBook and iPods and could not hear any significant change in the sound-signature (obviously discounting for the differences between these sources).
They sound good out of the box, after about 50 hours of burn-in the change is not that dramatic, but I feel they became even more frequency-response wise and extra level of detail unlocked.
I definitely recommend them and currently pretty much stopped using anything else, as all ear/headphones I have now obviously show their deficiencies and (in some cases) - tantrums.
