Seems like this pair of IEMs has lost traction. I, as well, wonder how it stacks to the IT01 which apparently has been a much more popular IEMs sub $100. I might never know the answer, lol

I own both KC06A and the KC09, been listening to the KC09 for a good half a year.

I wouldn't call the KC09 a upgrade...its got more low end bass. I would pick the KC06A anytime of the day.
The cables of my KC06A cracked due to its material and its the only thing thats stopping me from purchasing another pair.

I am still looking for a successor to the KC06A. If anyone knows what is the upgrade to the warm-neutral signature of KC06A PLEASE share!

I'm not sure why Ostry's IEMs remain almost unknown on Head-Fi, but on Russian and Ukrainian market Ostry KC06A became a real huge hit. They offered indeed good design and pretty balanced sound for that money.

Now Ostry are back with higher end KC09 model, it's priced about $200, but it looks good and sounds pretty good too.
KC09 uses single DD with 10mm diaphragm, offering pretty neutral signature with accented lows (this can be tuned via tips)

​

Other specs: 32Ω of impedance, ≥101 dB of sensitivity, 20 Hz – 20 kHz
Cable is replaceable with MMCX connectors

The Ostry KC07 already hit the market. Have a chance to try those yet? If yes how do they compare to 09 in your opinion?
