These blanket statements are getting ridiculous, and I'm starting to suspect you're unfamiliar with what "objectivity" means. No, that's not even the PRIMARY reason people buy headphones, which is: because they like how they sound (or at least suspect they will due to other people's impressions and descriptions) and a good deal of the time that has nothing to do with accuracy.
Yes its objective, but most people buy headphones blind without testing them first.
Meaning they do research online, look at frequency graphs, other reviews and peoples postings here.
They usually purchase more expensive headphones to get better SOUND QUALITY, otherwise you can just purchase some $20-40 headphones. Which is what most people do and they are "fine" with how it sounds.
If you are an audiophile then you are already searching for higher quality sound than what is available at your local store for $100 or less, or you don't believe in just buying blind.
So your subjective comments are just that, subjective. People don't become audiophiles because "they just like how that headphone sounds". Normal people don't go out and buy $800 headphones because "it sounds cool". Its for an objective reason, hopefully in the end they "like how it sounds" but as I said before... most don't audition headphones before purchasing them. And since not everyone's tastes are the same its why some MFG's allow returns within a certain period of time because the headphone might not fit their taste. Even if you are a basshead for example, you are here looking for headphones with MORE & Clear Bass with better Bass extension, etc.
Otherwise you would just buy beats with 30db bass boost and call it a day because QUALITY is no a concern over QUANTITY.
These Aeons sound great TO ME and they have incredible ACCURACY and TONALITY. Which is what I am looking for in a headphone, the isolation and comfort is also great which is a factor for me aswell since I often listen for 4-10 hours a time (almost every day).
I'm not sure why people get upset when I explain very simple things on this forum, such as that we are here pursuing high QUALITY sound vs the average individual.
If you like your sound different then you can alter it any way you like with any combination of hardware that you like or get a different headphone entirely. But to get mad at other people who are explaining the purpose of such high end products is overly ridiculous.
I brought these to a HeadFi Meet and everyone who liked analytical listening or tonality loved these headphones, some other guys liked smoother and bassier sounds and were more interested in my D7200. There is nothing wrong with that, and surely nobody was upset at anyone else for liking a different headphone or having different tastes, so why should this forum be different?
