Interesting. Do you know how to tell which headband a pair has?
The the flatter one on the left is the early version,the rounder one on the right is the later version.

The NAD Viso HP50s didn't sound or measure close to neutral without EQ and they still got a recommendation. It just depends on achievable performance, price, and competition.I have a question
If it sound neutral or harman neutral, you cant recommend it? I mean there is a lot of headphones that arent made for neutral or harman neutral FR.
For example lcd 4 and MEZE. Empyrean arent neutral and the people dont wanna these headphones neutral.
You are correct. "Room Feel" was the (goofy) marketing name given to following the harman target curve.
With the left and the right FR being completely different, plus this result being quite different than other measurement on record, I'm not sure if we can read much into this FR. I used the oratory EQ settings as a baseline and got very good results and those are based on much different FR measurements that tracked close the the harman curve. I'll try amir's eq later and report back.
First a quick correction - I am currently using the parametric EQ settings documented here ...
https://github.com/jaakkopasanen/AutoEq/tree/master/results/oratory1990/harman_over-ear_2018/NAD Viso HP50
So, I tried amir's EQ settings on my HP50s and compared them to the above and no eq. Amir's eq settings sound great to me - better than the AutoEq settings above based on Oratory's measurements.
I'm surprised. Here's my *theory* on what's going on: the HP50s measure close to the harman curve in a controlled lab setting. But more than most headphones, getting that ideal placement and seal is tricky with the HP50s. Amir's measurement techniques (however he is doing the averaging) gets closer to the real world experience under typical usage and his simple EQ settings focus on the gross errors instead of micro corrections that may not be entirely accurate.
Or, I'm just reacting to a FR balance that sounds good to me simply because its different. <shrug>
I totally agree that impedance is flat but the graph suggests otherwise, due to the blown out y-scale with large offset. One really has to study the y-scale to see it. Edward Tufte calls this a lying graph in his book The Visual Display of Quantitative information. May I suggest that future impedance graphs always start at 0 Ohm (preferably also for the speaker reviews)?

No, no. If you randomly place the headphone on the fixture, you will get large variations. But I am able to dial out 90% of that with ease with headphones with lager cups. So far, these NADs have been the worst in this regard. Just touch them and response changes massively. I am talking 10 dB up and down.
We will have to see how common this problem is as I keep testing more headphones. So far I am hopeful that it is not a big barrier. Even there, I had no trouble coming up with good equalization so using some intuition and judgement helps.
File this one under "no point me trying, cant use small cups/ pads". Which should be question no 1 for all headphone considerations.
Seems like this one has long beeb known as a hidden gem. Note to readers- apparently the HP70 wireless (currently / recently seend on Drop) are NOT simply a wireless HP50- so dont go thinking your are getting this with Bluetooth.
What I read was more about the components than the response.The HP70 doesn't differ too much from the HP50 actually, both matching the Harman target quite well, although the former is lacking in sub-bass.

I think we might have to agree to disagree on that.Well it's the final acoustic response that matters to the listener, not how and with which components you get there.
