The _acoustic damping_ makes the headphone shell surface non-reflective.
The side of one's head is both absorptive and not flat, so it is also
non-reflective. There are anomalies, but they are small in relation to
the headphone's non-linear response.
The side of the head is actually very reflective. And you are going to
have to explain this non-linear response. I've never seen it.

Now, you explain your very reflective head.
Again, not a word about non-linearity. And the reflective head. You
are going to have to explain how it could not be - you are in the land
of ducks having no echo here.

Sorry that you didn't understand the curves in the tests, since they are
the definition of audio linearity.
I have no idea what you're talking about regarding duck echos.
Those curves are frequency response - also known as flatness.
Linearity is a quality of the transfer function - distortion to you.
Please try to use the right words.
