Most people aren't audiophiles or even close and can't tell the difference (except that there is less bass brah!)...just be thankful that you can and that you find enjoyment out of it as that is what matters most. Even in the audiophile community there are varying levels and preferences - some prefer a smoother, more organic sound and others prefer a cold, super-analytical sound. To each his own I say, and just because I may be more sensitive to a higher level of treble doesn't mean that it's bad, just not meant for me. Some people want transparency and some want added flavor to their sound...there is always a balance for your own tastes and it's slightly different for everyone.
Specifically for the BE, I had a few people say they sounded amazing and others were not impressed (most were not impressed haha but the others were actually musicians). This is why you'll see 95% of people have either EarPods, Bose or Beats...I see it every day. It's all marketing and popular brands with endorsements/reputations will sell regardless. It's the same as you'll see most people have average commuter cars, or most people will have average LCD screens, or standard computers...it's all about personal interests and preference.
i agree that to each their own flavour, i own a few iems with different sound signatures (for the most part) and i enjoy all of them.
thats why theres an endless sea of iems or other gear out there. but it seems like the public only sees the 3 you listed.
obviously favoring some over others but i agree with your second point regarding everyone using earpods, bose and beats. and blast them to some insane volume. that i can clearly make out the lyrics sitting next to them.
clearly the earpods are not intended for subway or public transit use if you have to turn it that loud. i wonder how that thought doesn't cross peoples minds? lol until they go deaf. it actually bothers me that even some youtube reviewers make statements like "they don't isolate that well, but if you bump up the volume, you won't hear anything outside anyway" no duh, but you wreck you hearing..... there needs to be some advertisements for hearing loss
