MisterAudio.com is truly the Web's best place to find good cheap earbuds. For those who may not know, earbuds are basically a type of miniature earphones without all the awkward bulkiness that traditional headphones have. To "get scientific with it", you insert them into the "concha ridge" of the outer ear, which provides a more uninhibited travel of sound from the speakers to your ears. A good advantage of earbuds is that they are lightweight (definitely not a characteristic of traditional headphones), they are portable, and in general they're just easier to work with. A lot of people refer to earbuds as "headphones" or "earphones", but when it all boils down to it, none of that matters as long as they achieve the sound that you desire.
