I guess this happen to everyone here,
Anyway, you shouldn't take that seriously over your buddies, this is your hobbies and not everyone understand what you've called "good" or "bad", and it applies to everyone.
I don't have any technical experience for commenting this post, but from my past experience, which happen long time ago, at time I wasn't aware about headphones & audio stuff.
I was reading a game magazine, and there is a review about headphones, at that time, the only headphone's brand that I recognize only "sony", "Panasonic" or "Pioneer", and the most expensive is the best. But that day change my life, a word "sennheiser" came up.
After a while, I was walking with my dad, and pass an Audio shop, suddenly I recognize the words on the banner, "Sennheiser", then I told my dad about it, and we go inside the shop. There is alot of Sennheiser headphones, all inside box and I don't recognize any type or whatsoever about it, so the shop owner ask me to try on one of the headphone, so I choose one (randomly) and try it on.
He open the headphone and plug it into a black amp (quite big and looked retro/vintage), then he press "play" button on the CD player.
The first sound that touch my ears, were so beautiful, I can't express it with words.... at that time, I wasn't have any knowledge about sound (sq, bass, midrange, etc), but that day, I recognize straightly this is GOLD. My dad has similar reaction as mine, so we agree that there is grade in audio, that determine sound quality.
So we're tempted to ask the price, and too bad the amount money that shop owner ask is way above our budget, so we don't buy it (we can't) and keep the moment in our heart.
Then right now, I kept buying stuff (headphones, amp, etc) to search that 'holy grail' - and my girlfriend and friends keep asking, why would you keep buying headphones? Isn't one is enough? although they understand the quality of my stuff but they said it's not worth for the price.
The moral of story, not everyone understand, but some understand, some feel it, some don't, so don't feel bad if people around you don't understand what you feel, beside isn't friendship much better than your hobbies?
ps. sorry for sloopy post :P
