Reply to comment by atyne_mar in Sincere question: does technicalities exist, or everything what matters is FR graph? by Then-Effective5434

Well, except the FR is not the same at all. I'd expect the overall tonal signature to be be fairly close, but all those little squiggles are audible qualities of the sound, with some fairly low-Q >3dB differences exactly where your ear is most sensitive.

But what are you going to do about it, have some kind of EQ with dozens of high-Q filters that would be completely different on your particular cans/ear or even headphone seating? Ultimately the FR measurement is only useful to a point.

With headphones I have understood, that you really can't EQ 6xx to the Susvara sound, due to so much variables and differences between them, but still interested in Elex/Clear/Utopia case, because except pads, they all have same housing, and overall very very similar to each other

Also as I understand with IEMs it should be easier to recreate sound of one IEM to the other, even if one of them have 1 driver, and other 12 for example?

Let me give you another example. 58X and 660S have the same signature with very similar tuning and spatial qualities. 58X has just more bass and treble. But even if you EQd them to have the same FR, 660S would still sound miles better in terms of resolution and dynamics.

I think you could get them to sound very close to each other in terms of their broad tonal signature, but the devil's in the details, which show up as those little narrowband wiggles in the FR plot. For the most part that stuff is simply not amenable to correction via EQ. The Utopia and Clear may be similar, but the drivers are made of different materials, they probably differ in the finer points of their driver/enclosure design. Some driver distortion mode may very well show up in an FR, but you can't really fix it without fixing the driver - at best you could reduce whatever frequency excites that distortion, thereby probably doing more damage to the sound.
