What's nothing measures well?
Let's take the Celestee -

"I was pleased with the tight matching of the low frequency response to our target curve (dashed blue). What I did not like was the droop in the green channel below 80 Hz. I tried to compensate by moving the headphone around but no matter what I did, that large discrepancy remained. Looking at a few other measurements in the field, they also show a mild version of this "kink." It is very surprising to see such mismatching from a company like Focal with its extensive driver manufacturing capabilities."
"Very low distortion" plus "More impressive given excellent bass response". Though, didn't get his recommendation due to what seems to be mostly pricing?
Clear -

"Let's cover the good news first:
response between 1 and 3 kHz follows our preference curve unlike a number we have tested so far. Bass response is also higher as well. Misses are the overshoot between 600 and 1.6 Hz. The lower range of this from my speaker testing usually hides some detail in the music"
Didn't get his recommendation, mostly due to the clipping?
Elex -

"Very low distortion > 200 Hz"
"I may be biased by distortion measurements but I constantly went "oh that note is clean!" This happened across the board in many tracks. Quiet notes were especially a delight with the Elex."
"I am over the shock of the driver limit that I had with the Clear and decided to upgrade my rating of Elex to "recommended.""
This is against the target Harman researched
preference curve. Wouldn't say none of them measured well, but yeah, no headphones are perfect and what may sound good to you may not to someone else.
