I didn't say the wood conditioner was in there.

I'm not sure how else to read what you wrote earlier then:
 
"Ha! Guess what was the first thing I checked for when I opened the box? The second I saw them in the wrapping I thought  'no... theres been a mistake'
 
I've seen an unhealthy amount of lcd 3 unboxings and eBay sales and seen the ones the with the conditioner. It immediately came to mind when I saw it lol."

'it' being the yellow wood. 'Them' being the headphones. All about context brother - that and previous comments. Though I can understand how it was taken the wrong way. But I did clear it up before Audeze replied with another user.

Me and you have disagreed before haven't we. I hope to you searching for more of my mistakes going forward.

Care to weigh in on the cup having a tear in it? Or the connector being stuck? Or have you just got that to add?

Have a good day.

  When transducers are measured, typically an IEC-standard baffle is used, where we see very tight and consistent response. Audeze’s transdcuers are matched in pairs using IEC Baffle.
 
<...>
The ones we publish use a Neumann KU100.

At the time when the drivers are matched using IEC Baffle, is the fazor element already installed, or does that get glued on later?
 
Are the final measurements made using a fully-assembled unit, with pads?

Interesting that the serial number now starts with 282 instead of 271.
Usually it changes when Audeze have made some serious modification like adding the Fazors.
Hmm.. maybe it's just due to the different would finish or maybe they added the Fluxor magnets

Neither. The serial numbers are pre-printed and we ran out of them.

Yes. When measuring in IEC baffle, fazors are already installed and final measurements are with fully assembled pads.

No, on the posts, it is just one channel. The left and right ear in the dummy heads are different as it is in real life. When you buy the ears, you have to specify which ear you want.  So the Left and right measurements usually look slightly different even if the transducers are perfectly matched.

Absolutely, that is where all other elements of the assembly, including the earpads and their fill density, get factored in.  So in the example above, where the earpads are either uneven in their thickness or fill density (both of which are quite frequent in LCD series), there is a rather high possibility to encounter channel imbalance (as seen in this thread).  Unfortunately, that does not get reflected in the graphs available to customers.

Millhouse, Not trying to argue here, but the point I was trying to make was, the artificial heads / ears are based on ITU-T Specifications and the left and right ear are intentionally made differently. So, even if everything is exactly the same in the headphones, the measurements will look different. In humans the left and right ears are quite different as well. A few years ago, for R&D, we measured the HRTFs of several of our employees / engineers and we used special microphones (claibrated) that measure the sound near the ear drum with the same source. The measurements were quite different from each other.
 
 
Will post more information on fill density / thickness after checking later.

I must admit that I really don’t understand what you mean by this. The left ear is different to the right in what way accept it is on the other side of the head? Sure my left ear is different shaped to your left ear that is different to a third person’s ear and so on.

 

The difference between the sides of the head are dealt with by the angled pads, as far as I know. For other headphones or speakers with drivers that are angled I would understand this but not with yours.

In reality, the shape of the left ear and right ear are quite different for almost everyone. They are not exactly the same.
 
Measurement of frequency response for headphones using artificial heads is very different. There are different ways / places to measure the frequency response. 
ERP, EEP, DRP (see image below). In practice mostly EEP and DRP are used. 
 

 
As the sound from the headphone goes through the pinna , concha and the ear canal, the frequency response is modified. 
 
In most adults, the left and right ear are not similar. The shapes are different even between the left and right ear. Recent research suggests that we even hear differently between left and right ear and most people prefer right ear for spoken words. 
 
The Ear canal specifically changes the sound between (2Khz and 4Khz). The amount of change in the ear canal (ear canal resonance) is dependent on the particular indivudual’s length, shape, curve and volume of the ear canal. In addition the shape of the pinna, concha shape the frequency response as well. The smaller the ear, the more accentuated the high frequencies are. 
 
So when the artificial heads were created, they designed them to mimic human hearing. They sampled and averaged thousands of heads and ears and came up with the artificial heads / ears. 
So the left and right ear in measurement systems are slightly different. 
 
When we put headphones on the heads and measure them at EEP  or DRP,  even if we use the same source (eg - speakers), the frequency response picked up the the calibrated microphones will be slightly different because of the differences in the shape between left and right ear.

I still not sure I get it. Do you mean that the left ear channel generally are shaped in one specific way and the right generally are shaped in another specific way? Might be true, but I have never heard of that before. That they are quite different shaped between people I already know. It’s why they measure them for costume made in ear

This is valid in the context of psychoacoustics, however, it does not explain the reason why such variance in frequency response exists between left and right channels of these headphones, particularly since most of it can be attributed to the shape and density of the pads.
