so i recently became an audiophile (or wannabe audio buff). as anyone, i look out for my friends, and one of mine had stuck with the apple ibuds for a long time, and he seemed frustrated with them, but he never bothered to get a better pair of phones. so i let him try my m50s one day, and he was astounded by the sound quality. so right there and then, I suggested a bunch of sub $100 cans. just recently he ended up getting the srh440. so now that he got a decent pair of cans, im now trying to stop him from listening to green day which is imo, a disgrace to music in general. any tips on how to convert my friend into loving something else other than those mascara wearing freaks? of course this is his preference, but i just cant stand the fact that he talks bout green day every time we hang out.
