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.

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.

** In the world of "audio" linearity is synonymous with low harmonic distortion.

Transfer linearity, linear excursion etc.

Only in the world of *audiophoolery* it becomes something else.

** ROTFL !!!!

" A duck's quack never echoes.... "

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.

** Dear NG followers:

The odd looking response curves published on that *amateur* site are the result of the test set up - which is described in the vid as being ".... not actually made for measuring headphones ".

All the dips and peaks at top end are test anomalies, so is the LF roll off.

IMO the ONLY way to sensibly evaluate headphones is to wear and listen to them for a while.

IME ES models win, hands down on sound and comfort grounds.

It is also interesting that the site used a powerful amplifier to drive the various phones - rated at 24W into 32 ohms from its "balanced" headphone connector. That is enough to smoke most phones and your ears in a fraction of a second .
Very stupid.
