Man, I put these values in the Equalizer APO and my MH1C sounded unbelievably good, My sample is a little more nervous on Bass, so, I reduced 3db from 315hz to 20hz.
Before that, I simulated the ER3XR FR curve on the Cora, using the Heavymetal Helellujah' graphs. The result was very good, but not as good as this.
Can you do a etymotic simulation on Tanchjim Cora? I will be very grateful if you do, or if you post any that you have already done. Thanks In Advance.
First of all, that was just to prove a point.
Secondly, cora is different from mh1c which is almost completely peak free in the highs, is has some peak at around 7khz. And that differs from person to person. It's doable but as insertion changes it will change eventually.
Here is how you do it:
Firstly use tone generator (10% or less volume) to pick out the peaks at high frequency (7khz-15khz) and eq them out. And then use music with dense frequency response like metal to matched the bass mids. Mids is very very sensitive in metal music. So that's the trick I use. I basically only use first few seconds of the tracks. Some tracks are
Architects-Gravedigger
Architects-The devil is near
In Flames-My sweet shadow
In Flames-Like you better dead
Omnium Gatherum-Nova Flame
Omnium Gatherum-New world shadows
Mors Principium Est- Terminal Liberation
The some other tracks to further fine tune.
Trust me classic music and vocal doesn't work, electronic can be useful for bass some times.
Use 15 band eq first. Then add 31 band to match. After that you can add another variable to fine tune further. The eq I posted is just 31band. Close enough. Make sure there's minimal to none red region other wise there can be clipping causing distortion.
Oh btw the eq profile I posted also includes the "flaws" of er4. So there can be further improvements. For example: add a bit 800hz and reduce a bit 1.6-2khzkhz, then add a bit around 7- 8khz and 13khz. (may also use tone generator to make sure 7khz - 15khz is peak free) This will sound less ety like but it will sound flatter, almost lack characteristics even. But then you may realize the recording is very very lively and transparent to you.
