@amirm, I don't know if this has been suggested already, but you might also try cheaper measurement solutions (minidsp ears, etc.) alongside this one to see if the difference is worth the expense. That alone would be an interesting test!
You might even be able to somewhat calibrate those cheaper solutions based on the B&K and end up using one of them for future headphone measurements

Checkout oluv's gadgets. Basically he brought down all the hyped shit. Only a couple of them are good til now.
Yes sure.
A great choice for a very cheap pair would be these Sony MH750's for $11.49, cousin to the legendary (albeit short-cabled) $5 MH755 which are now almost impossible to find, at least in the US. Those MH750's would be a good example of how a Harman-sounding IEM measures/sounds (Oratory measured them to be pretty close to the target except for a sub-bass boost, with an Olive score of 75/100, one of the highest he's measured).

For IEMs. Apart from mh1 and mh755.
Everything from Moondrop works fine. Er2se and er4 would help tremendously.
But I've seen measurements of er4 done on 5128. Not liking it.

I want to see a popular pair of wireless bluetooth headphones measured so we can see how they stack up to "audiophile" grade headphones.
@amirm If I ship you a brand new pair of the Sony WH1000XM3 Prime shipping gets them to your house on Monday. Will you be able to test them & return them to Amazon within the next 30 days?

Not as good as Bose QC35 mki and mkii

Unfortunately this will not be possible. Primarily because the miniDSP EARS doesn't have the same acoustic impedance as the human ear. And its compensation curve is not only incorrect, but it's incorrect differently for every headphone, so you can't even properly correct for it. Oratory explains this all in detail with measurements in this excellent post. MiniDSP EARS measurements aren't really much use.
Only read their RAW measurements.(but you need to know how to read them) Never take the written review seriously.
I own a pair of the Sony's.
I've heard both also, bose sounds flatter with a bit warm tilt, Sony is just too much bottom end and doesn't sound very natural.

Thanks. I had been looking at the "hammer" before seeing the 5128. Maybe I ask for an eval of that after this one.

No, it will have to go back the week before on Friday. So it is only next week that it is here.
I would like to see a test of a "popular" pair of high-end wireless bluetooth headphones, so selfishly I choose the one that I own. If we think that a different pair will be more valuable to test, I'm happy to send those to Amir. To name a few...
- Bose QC35
- Bose 700
- Jabra 85h
- Sony H900N
- Senn PXC 550

The AKG I have is Bluetooth but I won't be feeding it that way.
Understood, all of these can be used wired. My impression is that the ones I have listed are far more popular than the AKG N700NC. Using count of Amazon comments as a quick proxy for popularity:

If amirm is too busy with testing, I would suggest that amirm can cut down the writing. For amps and dacs that are bad amirm can just post the result and write nothing because it simply does not worth your time to write anything. For headphone testing everyone said the frequency response would be hard to get accurate, but there are still many things like distortion and CSD that can be measured. Also we can try to do something that other people rarely do like soundstage measurement. Headphone measuring seems like another rabbit hole accoding to this thread, armed with lots of knowledge is the way to go.

@amirm
Maybe this is something you could partner with another party on. A few headphone testers take part in the forum substantially. It is just a matter of how much can one fellow do.
So maybe partner with someone who has experience testing phones and has a website, but no forums. Give them a sub-forum for testing here and provide support to them. Support in terms of buying the testing gear for instance. I suppose after the WhatsThe Best forum experience partnering my not sound too enticing to you. Maybe a situation where you retain ownership of the test rig and let someone else do the testing at their location.
