You are right about constructive criticism.Okay, well...I can assure you that I am not 90 years old with an upper hearing limit of 8kHz haha. Ironically, I'm probably one of the youngest people on here, and I'm pretty sure Animus is actually even younger than me. So if anyone has their hearing intact, it would probably be us! I don't mind constructive criticism (heck, I encourage it!), but your comments are out of line.
I'm 56 now, so I'm suffering from the "Felix De Laet" syndrome (aka Lost Frequencies

But even much younger people may have lost the ability to ear "well"!
The graphs are objective not the perception of "sound quality"!
And then, our echoic memory are not that robust!
With this in mind...how someone can objectively say that, iem X it's "much better" than iem Y? And most of the time, from what I inferred from some reviews, the reviewer not even have iem Y anymore, it's just from his memory!
I understand and really appreciate the effort to make the reviews but I see it as an opinion, nothing more nothing less!
I really would like to see a musician "reviewing" our precious audio gear and tell us "this one are the ones that best reproduce the sound that I imagined for this track". Maybe we would be surprised by the results

And of course...this is just my opinion

Cheers.
