I can most definitely try but, usually the techs are not effected by a simple EQ. That usually comes down to more physical stuff like the actual driver quality, the seating, shape and material of the shell ect.
Understanding the differences between Olina OG and SE (both stock: OG has more upper-midrange bite, SE is more warmer-neutral):
Iād say EA500 threads the needle between OG and SE, where EA500 is more energetic than SE but just a touch less energetic than OG where it had a little too much bite for me, so if OG was just over my line for upper-midrange energy, EA500 is either right on the line or just below it, IMO

Exactly, but it could be fun to try and see anyway 
Nice observation! Canāt be a coincidence.
Just ordered my 2nd set from Aliexpress for $59. Cant beat the price for such a competent iem. It performs much higher than its pricetag. My first set is permanently on my nightstand to compare with other iems. Great find guys!

I guess it could be the same case as the planar iems.
Same OEM with the āsameā driver with some small differences.

The funny thing about that is how Dunu gave this impression that the āeclipseā driver they put in sets like Zen Pro was proprietary, and yet here we are with a driver that looks like a clone to it, if it isnāt the same one.
Silly chi-fi, we canāt take you anywhere, can we?
The Eclipse thing with the FP is different from the Zen. Afaik in the FP, its basically just a driver they found that fit their requirements to be called a āeclipseā driver.

Eww, thatās gross marketing then

yes, its definitely pure marketing. Compared to the Zen driver at least.
has someone done a teardown to see if it actually looks/is the same?
EA500 and FP? Afaik, no.
SIMGOT EA500 REVIEW
Hey guys! So, word has been going around that the EA500 is the new benchmark at $100ā¦ and I gotta somewhat agree - itās pretty good. But before we start shout out to Simgot and Linsoul for sending me these, go check them out, but with that said letās just jump into it.
First letās talk about the bass. Itās pretty great. Probably the best quality under $200. The impact, slam, and weight to the low-end is very well done. Itās thick but well-separated and has great texture especially in the mid-bass. Simgot definitely did not cheap out on the driver in this - the low-end is very physical, and although itās mid-bass focused the sub-bass isnāt lacking either. Now, itās not going to sound like a sub-woofer, but the rumble is there and enough.
However, one potential problem is that the EA500 isnāt going to be the most neutral and ācorrectā sounding when you compare it to the Quarks DSP for example. I do hear masking in the lower-mids, and female vocals definitely sound huskier and warmer, so the clarity isnāt going to be as good as the Quarks DSP, but the mid-bass is very satisfying. And I do prefer the black nozzle more because it has slightly less mid-bass which helps with clarity, and also less treble which allows the vocals to be smoother and less sibilant because I do find the red nozzle having too much air when it comes to certain tracks.
As for the mids - itās pretty clean for the most part. Again, vocals arenāt going to sound as open and clear versus the Quarks DSP which has less mid-bass, but theyāre not congested either - just huskier. Personally I would still pick the Quarks DSP because it sounds more open and natural, but I can see the appeal of the thicker tonality. The EA500 definitely leans on the warmer side, so if you found the Quarks DSP to be thin or lacking in note-weight then the EA500 fixes that at the cost of some clarity. But the bass texture and impact is much better on the EA500.
Treble wise the EA500 is nicely extended - itās smooth for the most part although the peak at around 13K does hurt scaling and brings too much energy to vocals and electric guitars at higher volumes. Because of the thicker mid-bass, the extra treble energy gives the vocals a nice sparkle to balance out the thickness, but again it can get too much with the red nozzle, whereas the black nozzle adds the air and sparkle without going overboard. But either way, I wouldnāt recommend either for high volume, and dynamically speaking the Quarks DSP is noticeably smoother in the treble and uppermids - so again, I would still take the Quarks DSP in-terms of pure dynamics.
And for those wondering if the EA500 is a mini-DM - no, unfortunately itās not. The DM is just way more balanced and smooth. Compared to the DM the EA500 has more treble and uppermids energy, creating a bigger contrast from 200hz to 2K, as well as lacking the scaling, staging, and vocal finesse of the DM. For example, if the vocals and midrange on the DM is airy like a glass of high end champagne, then the EA500 is a very tasty glass of sparkling cocktail. But, I will say the bass texture is very similar on both. So, if youāre looking for the best quality low-end under $100 or even $200, then the EA500 is a pretty good choice.
Comparing it to some other benchmarks like the Olina SE and Hexa, I prefer the EA500 over both of them because of its bass quality. The Olina is similarly graphed but can sound light and lacks the note-weight and low-end slam, whereas the Hexa can sound too hollow and thin, and I really donāt see the point in getting the Hexa when the Quarks DSP exists which does the neutral signature more correctly with similar clarity, better dynamics, and also costs like 4x less. Now, the EA500 isnāt going to have a stupid amount of bass like the ROSEFINCH but it does have the best quality bass Iāve heard until the Serial, and although it doesnāt sound like a subwoofer like the Khan - the driver quality and low end texture is better.
So, if I had $100, I would grab the EA500 and Quarks DSP to have a taste of what a high quality low-end is, and what a ācorrectā IEM should sound like. And to put the cherry on top, the EA500ās metal-build quality, nice cable and case is also probably the best at $100. So ya. Although itās not going to sound as clear, correct, and smooth as the Quarks DSP Iād still recommend it for its bass quality and thicker tonality. Comparison with the Galileo this weekend, but for now - thanks for reading!

Thatās ok with me if all these IEMS do not sound the same.

Just stopping by to say Tool sound amazing on the EA500. Most things do, but this is definitely a case of me hearing/noticing things I didnāt in the past on songs Iāve listened to many times over. Always a cool experience when new gear does that for you. Might have to switch over to remastered King Crimson or Jethro Tull next.
