Adam Audio H200 (Gras 45CA Measurements + Earpad Dimensions)

There's another measurement on Squig.link so you can use the AutoEQ feature of that website.
If you want to use the measurements from the opening post, you'd have to play around with WebPlotDigitizer to get a frequency response in a CSV format that you can use in AutoEQ or Squig.link

Can anybody point me in the direction of an Eq correction Preset for the H200 which i can use on my Qudelix 5K?

About the only part that makes sense correcting on the H200 is the midrange/lower treble response.

For this, I took DMS' DF compensated 4128C frequency response graph and created a simple correction:


Bass response on the H200 is super volatile, so I'd advise against trying to correct it based on HATS measurements:

Wow thank you so much Friend!

I bought them cause i read here and there that they probably dont need a lot of correction.

What do you mean by bass is „volatile“ ? Do you mean its better left alone? Sorry non native English speaker here

Cheers !

The H200's bass response changes a lot with how well the earcups seal against your head, moreso than comparable closed-back headphones.

That means that the shape of your head, your hairstyle, whether you wear glasses, and other factors all impact the final bass response that you will hear.

It'll likely even change a bit from day-to-day differences in how you put on the headphone.

Hence, matching a target response based on a single, or even the average of multiple measurements on an artificial head and ear simulator like the GRAS 45CA, does not make much sense.

A-ha ok makes sense.
Tbh i am having the issue that it has a bit too much pressure on the head for my taste. Back when i had the dt 1990 they were among the most comfy headphones ever.
And if the pressure was too big you could slightly bend them more open or more closed.
The H200 unfortunately are plastic and will keep their clamp feeling no matter what one does to them
