This might be my last reply, I'll try to sum it up. All you perceive in terms of headphone sound or any other sound is the frequency response at your eardrum.
This is affected by the measured frequency response of the headphone (on a dummy head, lets say GRAS), it's measured distortion/compression, and "headphone transfer function" (we'll call it) when you wear the headphone on your own head (which is how your own ear & head anatomy influence the headphones transmitted frequency response when measured at your own eardrum vs that of the dummy head). Your "micro & macro dynamics" that you mention, is literally just a semantic label you've put on an element of what you yourself experience when you listen to headphones, but whatever that is....it's explainable by the frequency response that is being received at your eardrum which is a result of all the stuff I underlined in this paragraph.
The other stuff you have to be mindful of when comparing frequency responses you find on the internet (Amir/Oratory/Resolve/Crincacle/etc) of headphones/IEM's, is what I mentioned in an earlier post to you. Namely the following:
- Unit to unit variation (ie manufacturing variance) - can significantly affect frequency response, and sometimes distortion, all depending on whether the headphone you're measuring has low or high unit to unit variation. Some manufacturers are better than others at this, Sennheiser do very well in this in my experience - low unit to unit variation.
- Headphone Pad Wear - affects frequency response. Are your headphone pads worn, were the pads worn when the person measured them.
- Measurement Procedure/Protocol: for best comparative accuracy when comparing frequency responses between 2 headphones, then this has to be the same. So hopefully you'd be comparing measurements from the same person, as each measurer will have their own way of placing the headphones, measuring them & deriving a "publishable" frequency response that represents their many individual measurements.
So given all these variables I've mentioned in the prior paragraphs you can see there can be some significant differences between a published measurement you find on the internet for your model of headphone vs what you are actually experiencing with the individual unit you are listening to. So I think you can't be coming up with theories about "micro & macro dynamics" (which you mentioned & which I think is largely a made up/irrelevant term)....you can't be coming up with theories about "micro & macro dynamics" based on your own experience listening to headphones vs the published measurements you find on the internet....you can't be using that information to try to say
well the frequency response is near-as-damn-it the same between these two models of headphone yet they sound different to me so therefore it's not the frequency response it's something else called micro & macro dynamics that explains the differences (or whatever theory you have concocted as to why two headphones sound different to you). In fact the reason you hear differences between headphones has been explained in this post - ultimately it's the frequency response you receive at your eardrum which is influenced by all the variables discussed in this post.
What a person can do though (in terms of language & understanding frequency response), is they can relate roughly what certain parts of the measured frequency response of a headphone can contribute to in terms of subjective experience and the often-used terms that describe changes to the frequency responses in those areas, the following graph for instance which comes from Solderdude's website:

I'm not sure that the graph above is a 100% sure thing, it's difficult to attribute words/phrases to what we hear, as a lot of it is semantics, but through my EQ experiments with various models of headphone I can say that I can relate to some of that graph. So it all comes down to frequency response, and you can put whatever words you want down to describe how your headphones sound, but hopefully whatever elements you decide to describe you've identified as being a property of a part of the frequency response. It's hard to do this as ideally you'd have your own measurement device to validate the frequency response of your own unit of headphone(s) to remove the element of Unit to Unit Variation & Pad Wear, and/or it would take a fair bit of EQ experimentation and related music listening to start to understand the ways in which certain par"ts of the frequency response influence the music elements that you hear. But it's all in the frequency response received at your eardrum.
