In case anyone wants to see the internals or want to find ways to mod it. These pics were taken over 3 months ago.
All disassembled:

After you remove the screws and the black piece:

The "wood":

Yup that's actually window screen:

That's not nanometer thick:

Fake wood, fake chrome, fake leather, and fake "nanoscale" diaphragm. Called it from the start :/

Yeeeep and most people lapped it up. Sads.

edited with embedded pics so you guys don't need to click the links!

Looks authentic "made in China" to me.

Is that a real HE1000? Apart from looking like a little less craftsmanship went into them than you'd expect from a $200 headphone, how do they sound?

Like a $200 headphone.

Actually, the fact that the diaphragm shows light interference (different colors, like soap bubbles) from all the pics of the driver and also seen a bit in your last pic means it's probably sub-micron. You can solve the rough thickness of the diaphragm by the color you see at what angle and entering all the details here (with some rough guesses on index of refraction for types of polyester film):

Another view of the driver (taken from HF). You can see the greenish tint at the top of the driver and purplish at the bottom from the light phase interference.
-
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.
-
Actually someone asked if it was a real HE-1000. I would have laughed, but at $3K, it makes sense to knock it off.
-
I can't believe that's actual fly screen material cut to size lol!! :)p13

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. :)
-
I didn't flip it damn it. Traded for something of about equal value.
Also this is the beta unit that was sent back to HFM. I did not bother to open up the production that is no longer mine.
I was afraid to touch the diaphragm. Didn't want to break it like jerg did.

I can't tell shit from that picture.
-
Do they use better materials in the non beta units?
I've always seen Hifiman as a price/performance value proposition where the sound and price are good but the manufacturing is mediocre. At least this has been the case with all the Hifiman IEMs I have owned (RE0, RE-262, RE-600) though they have been improving over the years.
I don't understand them releasing a 3K headphone.
-
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).
-
Compared to T50Rp it looks quiet thin.
-
lol this thing must cost like $50 to make, what a joke
3 grand and they can't use real wood and leather? :vomit:
-

That's audiophile grade fly screen.
-
I had a beta unit, but didn't have the cajones to open it up. I traded it for a production unit, and the second time I used it,
the head strap pulled loose on one side, so back it went for a refund. After seeing this, I'm darned glad I went that route.
-
I traded the beta for a production model. The production model only worked from one channel. I wonder how much it would cost to get sound from two channels? Let me get out my trusty calculator.
-
This isn't a joke? That REALLY is an a HE1000 right? :)p3 F'ed up.

LOL nice :D

Hi,
You can't tell with your bare eyes if it's nanometer thick or not. You can deposit few layers on a surface and you can see with reflection that there is something. If you can use an Atomic Force Microscope (AFM) go ahead but from here it's impossible to tell.
Though, people in nanosciences can tell you that 600 nm is nanometer scale. So telling that's nanometer scale when it's < 1µm is totally subjective (and good for marketing purpose I suppose).

Western universities and tech centers regard nano-material as something under 100nm in at least one dimension.

As I said, it's subjective. I did a PhD in Nanosciences and we consider few hundreds nanometers thick as nanothickness. And I think that's what the new Hifiman membrane is about, few hundreds nm.
