Yes there is one, but it is OOAK thanks to inconsistent QC. The very first DT3 I purchased was faulty. It has horrible driver flex BUT has a unique sound signature which I can only describe as a junior version of the SE846. I liked it so much that I ordered 10 more DT3s, only to find out my original one was unique. The other 10 DT3s sound identical, but have the usual KZ sound signature.
Other than that, unfortunately no
All KZ IEMs I've heard have two noticeable peaks that makes the signature sound not-so-natural. The first is in the 3-4khz region, and the second in the 7-8khz region. The first peak causes the high mids to sound slightly plasticky, and this is more apparent when A/B'ing with other earphones.
For the money, KZ IEMs are still unbeatable. They destroy the old Meelec models that cost around 3 times more, and I would take the ED10 over the Klipsch S4 anyday (even if the S4 was reduced to $10).
KZ IEMs are basically $10 "giant killers", where the giants are around the $50 range. However, the KC06 and Tenore are also "giant killers", arguably on par with the GR07 which used to be a "giant killer" itself. That term isn't as relevant anymore, because VFM has increased/improved significant in the past year. Five years ago, the Klipsch S4 was actually a good IEM for the money lol, whereas now we have KZ, T1E, MH1, Pistons etc. I have to say that the best VFM earphone I have is the Tenore which I purchased for 1900 yen. I hope it doesn't break though (them horror stories)!
