That is the purpose of this group. I'm glad you're beginning to figure it out. This isn't about winning an argument, it's about sharing information. If you didn't cling to you misconceptions so tightly, you'd have a lot less problems. It isn't polite to be silent and allow people to make mistakes, and it isn't rude to point out the truth. But you have to be receptive to information and not reject it out of hand because it doesn't fit your mistaken preconceptions.
Yes headphones do sound different from each other. Even two copies of the same make and model can sound different due to manufacturing tolerances. And yes, those differences can be measured. There are many sources of that info. But you have to know how to interpret the graphs. Transducers are mechanical and produce physical sound. That is a LOT more difficult to do accurately than to pass an electronic signal from point A to point B. Digital audio has solved the problems of fidelity when it comes to amps, DACs and players. The electronics are easy. The wild card are the transducers. There are good headphones and bad ones, and what might work well for your particular ears may not work well for someone else's.
If you want optimal sound, just going by your gut feelings isn't going to get you there. Random selection produces random results. You have to gather together real information, do your homework, and proceed with a logical strategy to reach your goals. You don't do that by throwing up your hands and focusing on your feelings. You do that by talking to people who know how things work and prioritizing what matters over things that just don't matter at all.
One thing you might want to think about is focusing your language a bit. Audiophiles use vague terminology like "resolving" and "layers". People who know how audio works refer to specifics of frequency response, distortion, dynamics and time. For instance, you mention cans that are more "resolving" which doesn't tell me much at all, but you mention a response dip at 2kHz, which is the range where the human ear is most sensitive. Small deviations in that area can make big differences. But to know that, you have to know what 2kHz sounds like, what part of the music occupies that range, and how human ears hear those frequencies. If you're actually interested in that, you could post a link to the two sets of measurements (it needs to be two sets measured by the same person because different people apply different compensation corrections) and ask for people to chime in and help you interpret those graphs. But if you're going to ask that, you shouldn't argue with them, especially if you don't know what you're talking about and they do.
It would also help to talk about one thing at a time. It frustrates us to explain things only to have our explanations ignored, and questions about three more completely different subjects heaped on top of the pile. We want to be able to answer a question, and any other questions you might have on that subject, before moving on to something else. When you flit from subject to subject to try to justify your subjective feelings, it makes it unrewarding for us to make an effort to bother to answer your questions thoroughly. That is when frustration creeps in and the temperature starts going up. Let us explain, carefully read what we say, acknowledge that you have read and understand, THEN move on to something else.
)... There is one aspect that people don't comment a lot and is "the mood"...
