I actually never meant to buy these at all.
I ordered the AK6 since all the reviews i read and watched online gave them an okay rating. But what arrived are not the AK6 but the CK5. The CK5 (from what i heard at least) is a notoriously badly tuned 2 dollars IEMs. I was curious , how bad really? So i went to answer these questions of mine.
It came in a case with extra tips , ear hooks and the IEMs itself. The ear hook kept falling off so i just gave up on using them.

Case and ear hooks

QKZ AK6
Bass: Just way too much amount. It sounds really loose and is missing that deep rumble, but what do you expect these are really cheap. It affects the midrange a lot, it's quite bloaty and the mids sound really bad.
Midrange: As explained, bass really muddy up mids. I also hear a slight recession on top of that. This is a really bad combo, since (mud + recession = less mids). It's quite forgiving towards male vocals but does ZERO JUSTICE for female vocals. When you expect it to extend it just doesn't and that makes me feel really sad😢.
Highs: On the other side of these flaming garbage are the highs. Don't even get me started. THE HIGHS SOUNDS DARK AND SPARKLY. And no, not in a good way. THE HIGHS DOESN'T EXTEND FULLY AND IS MISSING A HUGE CHUNK OF INFORMATION. ON TOP OF THAT IT HAS THIS AIR WHICH JUST MAKE THEM HARSH. IT SOUND LIKE I'M UNDERWATER AND CURRENTLY DROWNING.
Technicality: Bad technicality and has pretty bad separation.
Ergonomic: Some people said that the fit is really bad. I don't think i have that issue, though i will report that the stock tips are quite sceptical, since with some pressure on my fingertips the flap collapsed on itself.
Will i recommend them? No
But for those poor souls who accidentally or willingly bought them here are the fix.

I am not an EQ expert but these AutoEq files fixed most of the problem i have with these. You can adjust the settings according to your taste. But if you have an issue with my AutoEq files please care to point them out and fix them.
