Equalization according to measurement, experience.

[IVX]

I know, nobody has an interest in it at all but I can't resist sharing our success. I made HE400i EQ compensation to the Harman target curve for <3 min )) YouTube in googleplay officially. The new function could be called by tap and hold on on the filter's free area on the Filters menu, after that you'll see msg "Set background/ Clear", tap on Set_background and choose the pic(screenshot from FR Page not found - RTINGS.com... ). Mirror the picture and adjust horizontal position/size, next vertical and tap Done. Adjust parametric EQs according to the background, that's it. The function may be used without hardware PowerDA v2 i.e. 100.0% free. Enjoy.

Just tried minidsp ears. Garbage.

They do seem so. And for relative measurements I do not see any difference between diy plate coupler and minidsp ears...

But to be fair, you did not tell us how much time you spent tweaking the whole thing.

there is nothing to tweak if ears shape isn't right. IEC ear simulators have pinna peak around 3.5kHz, minidsp 4.3kHz and much more sharp(too high Q factor). I never saw such ears in real life, small and simplified like a free 3D model from 3dmax portal. EIC ears look like normal average human ears.
