I traded my HE1ks away already. Just feeling the bit of extra diaphragm out the edge of the assembly, it felt very similar to saran wrap. We already know that's not nano thickness.

Saran wrap doesn't generate phase interference like that. You have to be a certain thinness to phase change the color like you see - so I believe it's probably < 1000nm (if that's what Hifiman considers 'nanometer grade'). So you can either trust science, or your ability to 'feel' for thickness Did you actually take the screen off the other side and put the diaphragm between your fingers or just touch it?

Man, I'm glad I'm not the one that ended up buying the beta HE1000s that you flipped.

That's not nanometer thick:

I can't tell shit from that picture.

Didn't look like any internal changes were made when I removed the pads. Doesn't look like Fang was willing to make any changes in parts except for minor corrections (headband length).

lol this thing must cost like $50 to make, what a joke

3 grand and they can't use real wood and leather?
