Topic: .adieqpr EQ preset request for IER-M9

Hello,

I recently installed the ADI Remote app on my macbook and thinks it's awesome! RME was even nice enough to include a EQ preset for my HD800S headphones. It made a really big difference and improved the sound of my HD800s.

I was wondering if anyone has a preset made for the IER-M9 or can show me how to create one that matched the Harman curve.

Thanks!

Here you can find the settings from the AutoEQ project, for almost every headphones ever measured anywhere:
https://github.com/jaakkopasanen/AutoEq … er/results


Use the “Parametric EQ” filters No. 1-5, and maybe No. 10
Ignore filters No. 6-9.

Why it’s better to ignore the high Q, low gain filters above 2 kHz, see this video, specially from positions 7’30”, 9’25” and 12’35”:

Sony IER-M9:

Sony IER-M9 “no filter” (whatever that means):

Feel free to do your own tweeks on the EQ settings.



One has to be aware, that these EQ presets are more detailed than the measurement they are based on.
Harman Target is largely smoothed and doesn’t justify such fine corrections.

The Target’s smoothing makes sense, as person’s ear’s anatomics vary a lot, and are different from the measurement coupler used.

Even different seating of the ‘phones on the head introduces great variations.

Therefore every EQ correction above ca. 2 kHz has to be taken with a large grain of salt, and might not be an improvement.
The video shows how to check for this.

@KaiS Thanks that worked! I did notice that the built-in EQ preset for the Senns HD800S doesn't match the PEQ from the AutoEQ project you linked.

They look totally different. Do you know why this could be?

This makes sense MC! I much prefer your PEQ profile to the numbers provided by AutoEQ. I did tune your 8K high shelf down a bit to +2.0db but otherwise my HD800S never sounded better. Thank you!!
