You are presenting the differences like night and day, while in fact they are subtle. You would have a lot of trouble to be able to tell them apart in a blind test with music material, if you would even be able to do this at all. Looks like a very biased judgement to me.

you may be right, i may simply be conditioned by the measurement results and opinions of other users, i did not do a blind test and it would not be possible to do it with iem.
However what I can tell you is that I have no interest in "pumping" on one headphone instead of another, and my ratings are my sincerest opinion.
I ran the same test I had done with the salnotes, going from the Sennheiser momentum in ear to the Truthear, and I didn't have the feeling of lack of body at all that I had doing the same thing with the Salnotes.
The momentums remain more substantial in the bass, even compared to the Truthear, but they are lows that invade the other frequencies a bit, while the feeling with the truthear is that they are able to push deep basses where they are needed without creeping into the rest of the band making the sound dull. .
But this is a science-based site and I talk about subjective opinions, so I understand your point of view and your distrust.
What can I tell you, I immediately liked these as opposed to the 7hz salnotes.
