I've long been dissatisfied with bud headphones. They either don't fit in your ear well, or they fit so snugly that you can suddenly hear every physiological shift within your body. They usually only last me a few months at best, and sometimes much, much less than that. Also, they're bad for your hearing. Because they don't block out external sound, you have to turn them up higher when you're around traffic noise to compensate.
Plus, I just haven't been satisfied with the frequency response of any of the buds I've bought. They're either lacking in bass or high frequency detail. (This is also bad for your hearing.) Granted, I've never spent more than about $20 on buds, but why would I if they don't last?
slightly-better-than-abysmal version is a full eighty dollars.
I asked one of my friends to listen to a song with his Apple headphones and then blast that same song through the Sennheisers. When he was done, his only response was, "How did they fit a subwoofer in there?" Exactly. I've been listening to Dvorak, Bizet, the Beatles, Jack White, and it all sounds amazing. "A Step Too Far" from Elton John's Aida concept album just came on. This song has never sounded so good, not even on my Bose speakers that cost five times as much. The detail guys, the detail. I'm hearing all kinds of stuff I just never knew was there.
So although I don't want to look like That Guy walking around with the idiotic, hipster cans on his head, I don't care. I love music, and my music sounds unquestionably better in these cheaper, better, more durable, more comfortable headphones.
