I really can't believe my ears 
After getting Vsonic GR-07 and understood its sound (after burn-in), I am comparing GR-07 (170 USD iem) against KM-92 (4.5 USD iem) after changing my sound settings (completely on the opposite side for each iem). I can say that my KM-92 stands very well against GR-07 in many ways to my ears!
Especially bass and soundstage is great on KM-92 (to my ears slightly better). Only positioning of instruments are not so well on KM-92 but it gives you great, out of head sound! Compared to KM-92, GR-07 excels on positioning of instruments, highs and mid bass. For clarity and quality of highs each iem is comparably close for my ears. Hey what's wrong with these Kanen's?
If something are not wrong with either my GR-07 or KM-92, then something is wrong with my hearing ability
(as you can see on my sig).
I am using the same eq setting but changing the bass and treble settings for each iem on my Rockboxed Fuze V2.
Settings as follows: For GR-07: bass:8; treble: 0
For KM-92: bass:0; treble: 13
I believe that my KM-92 is from an excellent batch. Because I have also compared it with my Denon AH-C710 (I prefer KM-92 mostly), and I also compared my C-710 with my GR-07 -in the end I am selling C710- this means something is wrong with these 4.5 USD (including shipping from China to Turkey) iems 
Incredible value, bravo Kanen!
I am going to order another set just for comparison.
PS: I have also ordered Kanen KM-903 because of curiosity to this brand. But KM-903 is the worst of all earphones I have ever heard!
