Need one of these stickers for the blackest background and widest soundstage possible
Haha I don't know which is better for audio nirvana, this snake oil thingy or sticking HI RES stickers on our audio gear!
FWIW, I bought a bunch of HI RES stickers at the last Aliexpress sale!!!

I think people get off on trying to discredit others or a "hype train".
I've seen 4 graphs already, and this one doesn't match up from 20hz-400hz for me.
I'm not getting the same massive bump from 20hz to 80hz with stock tips. I am from some other tips, so ymmv.
The 6kHz dip is real. Boost a few dB and it's fine.
Cut ~60-100hz a bit, Boost 6Khz and 16kHz.
I'm A/Bing this with an HE6se V2 and Moondrop Aria on a Gustard X16, Monoprice 887, and Schiit Lokius. The HE6se V2 smokes everything, as it should.
The Aria has noticeably more bass in the same regions than the GK10. If you go by Precogs graph, the GK10 would have ~10dB+ more bass than the Aria. That is simply not true on my GK10. If you compare a bit more down the response, you'll notice the Aria and GK10 measure somewhat similar and both benefit with the EQ tweaks above.
So if the GK10 is crap, then the Aria must be hot garbage right?
Now that I've had a chance to A/B, I do think the low end could have been tuned a bit better, but I'm not hearing anywhere near what Precog is describing in the mids and highs. It still sounds better than the Aria, and that is punching well above it's price already.
Either QC is suspect (very possible for the $45), or Precogs measurements are wildly off.
(Not one headphone or IEM at any price range has not benefitted from EQ adjustments for me for specific songs/albums. If you don't want to EQ that's your choice).

Okay, so here's the scoop. The ports were sealed completely shut from the factory with excess glue or something, hence the ridiculous amounts of bass. I gently punctured one side with a needle and managed to free it, but the other side was gunked shut from head-to-toe. When I pushed the needle through that side with more force, it seems to have punctured the bass DD. Now that side literally no longer has bass. Even the side that has "correct" bass doesn't seem to graph like other measurements I've seen from the upper-midrange and up. I let InvisibleInk know about the issue (with an offer for $50 or to keep the Yume that I lent him). For further transparency, here are the measurements:
(labels for full puncture and partial puncture should be swapped)
Whether my impressions still stand, who knows. On one hand, this probably (mostly) fixes the bass bloat issue. But if there's less bass, then my issues with the treble are only likely to be exacerbated. I also largely framed my critiques within the context of the driver configuration itself. Either way, I think we can all agree that the quality control is not within acceptable parameters with this set. I've seen four or five graphs and they all look different; suffice it to say it's not my problem when a manufacture screws up like this. Purchase at your own risk.

It’s good to know. This is my chance to take one for the team. We’ll have to let the Geek Wold guys they need to check for glue in the vent holes before packing and sending out.Okay, so here's the scoop.

Obviously not your fault and atleast we have some explanation for unit variance now. You were only reporting what you heard. It is, however, everyones problem (including yourself) when we write/read reviews and make purchase decisions in the context of unit variance.
Geek Wold need to sort it out.
