Innerfidelity FR target

I realized the NAD VISO HP50 graph was off, here is what it should look like:


I was curious to see the original Tyll version of the anax mod for the HD800:


HFM HE-400S:


HFM Sundara:


1More Triple Driver Over Ear:


Audio Technica ATH-M50X:


Stax 4070:


Was interested to see how some Ultrasones would turn out...
Ultrasone Edition 8:


Ultrasone Edition 10:

6kHz peak of death... check

 

the weird thing for me is that I actually HEAR the big mid-high hump that everyone compensates out. not really sure how or why, but basically every headphone ever made has a huge like 10db hump in the mid-highs that makes them unlistenable for me. have to EQ it flat before compensation to listen to anything

 

You mean you hear a curve like the raw curves? So an HD650 would be 10db forward at 3.5kHz? That would be very weird indeed. Going from memory the SR007, Abyss and the Tascam TH02 (Teac CT-H02 on IF) look like good options in that case.

I do think I hear in-ears somewhat like that, where my target curve is essentially an inverse IEC coupler curve: Flat to 500-600Hz, then a 5-6db rise to 2kHz after which it's flat again. Or something like that anyway - I don't have a definite in-ear FR target yet.
