Abudephane, do get over your bad self.
If I bought expensive earbuds just because audiophile snobs like you snottily accused me of being an unwashed rube for not spending more on the right equipment that apparently all right thinking people should use, I would in fact be the sheep you seem to want to accuse everyone of being who doesn't care about exactly the same things you do. Not only am I supposed to buy earbuds, but I'm apparently supposed to spend the time, money, and energy to learn to care. Well I don't.
I'm might be a sheep for spending good money on an iPod, which everybody and their grandmother already have, but not buying another set of earbuds is simply making a choice based on my priorities; free works just fine for me. I listen to it on the train, hardly a conducive listening environment to appreciate the finer points of audio, simply to kill time, and as often as not I listen to spoken podcasts, so audio quality is hardly a concern. I did spend $100 to upgrade my speakers at home (and that was a bit of a luxury), but not $300 or more. Yes, I listened at the store, and no I couldn't tell the difference, certainly not enough to care. They are fine for the casual background listening I do.
So you like music and care about audio quality and can appreciate the subtle differences. Well, bully for you. I'm glad you found something you enjoy in life. Frankly I think people who spend multiple thousands on sound systems kind of crazy, but it's their money, and they're free to spend it on what the want to. I don't get, but I don't have to. I have things in my life that no doubt would bore you to tears if I blathered on about them, and would annoy you to no end if I lorded them over you as things you and everyone else in the universe needs to care about as much as I do.
