Headphone break in?

Yes. Headphone burn-in is a real phenomenon.

I made a burn-in clip years ago that works with all headphones, regardless of their driver type/technology. WARNING - take off your headphones FIRST as this will not sound good! It uses each of the important types of noise (white noise, pink noise, etc.) these in turn influence the movement of the driver units completely by the end of the video.

No need to play 100+ hours. My condensed burn in-in clip places enough strain on the driver units to have them conform to the designers engineering standard.

I've got a video for that too

Like all mechanical things (machines) speakers, headphones, and audio components "burn in" this means the settling of parts to the manufacturer's engineering standard. The same is true with a brand new car. 

I understand your opinions are humble, but that logic sounds very much like something an ASR minion would say.

That we are simply fooling ourselves in to hearing differences that are not real...

Misunderstanding.

Didn't say you were a minion specifically.

Didn't call you out.

Just saying.

And you're welcome.
