Of course everybody’s ears are different but that has no bearing on a headphone being pumped up in the low end. It just doesn’t .
Provided your anatomy and the HP's design enable a good seal then it's probably indeed the FR range that is the least dependent on HRTFs variations.
Which is why I brought up measurements to debunk your erroneous assertion that Apple's headphones products have a "bloated bass". Some Beats do. The AirPods and some other Beats don't. It's measurable. It's been measured. Done.
You keep to your spec sheet. I’ll keep to reality.
That's where you're wrong. I don't bother with spec sheets. I bother with measurements (to a limited degree), preferably from independent publications that publish their methodology - something that Sonarworks doesn't do BTW.
Reality, as demonstrated by decades of research in that area, is that your own ears... well they're not a reference standard (and neither are mines). And they just can't be because of physics (HRTFs and your anatomy in general) and neurological reasons.
That's also why decent headphones, including the ones you're using, aren't engineered by audio gurus with "don't lie" ears but by simulating, measuring them, and then moving on to blind tests with a variety of listeners.
That has no bearing on your capacity to be a great music producer / mixer / whatever and earn money from that activity.
Heck as a photographer I'm not that good at understanding calibration and colour spaces and it doesn't prevent me from getting the prints or the images distributed as I want them to.
As an assistant I've assisted some photographers who couldn't even operate a computer and that certainly never made me a better photographer than them.
