I know that it is not easy to measure headphones and i hope i can expand a bit on the method i came up with.
First i just EQed the measured response.
I decided to work only on frequencies over 2kHz and doing a treble shelf so that high frequencies remain at ca. 90dB.
This are the settings :
2kHz +2dB
2.5kHz +2dB
3.135kHz +6dB
4kHz +7dB
6.3kHz +8dB
8kHz +6dB

That gave a clear improvement.
Besides the presence dip that Nudell mentioned this cans also mute the mid treble a bit.
On the other side the EQ was not fully satisfying.
Strings sounded a bit stingy and my son said that the perspective on the orchestra was a bit strange.
Some instruments that should be in the foreground sounded further away and vice versa.

The next thing we did was using pink noise.
Pink noise is very good to hear frequencies that stand out from the rest.
We tried every 30 bands of the equalizer to hear what it does and after maybe half an hour we decided that it sounds very even, somehow like heavy rain i would say.
Switching back and forth it was clear that the un equalized response sounded a bit closed in and hooded.

@Joachim, do your not believe in the target response curve research that Sean Olive and others have been doing? Headphone Target Response Curve Research Update | InnerFidelity. That seems to indicate that 3KHz should be around 8dB above the 1KHz level. Or does the neumann head take into account the ear canal and give you a deviation from target response?
I come to this point now.
For the first time we thought that our EQ sounded better then the untreated headphone.
Still there was a lack of substance.
I then looked up what are the recommended target responses.
The ones i found are the Olive one you mentioned and the other is from Golden Ears.

At this time we certainly did not want to mingle around with the presence range.
The Neumann head seems to have some compensation. Otherwise the Audeze would be really lacking bad in this range.
Where both target curves agree is a raise in response under 200Hz.
We implemented that and, voila ! A big improvement.
