Not to sound like a broken record, but the stock plastic earbuds that came packaged with your shiny new MP3 player aren't doing you any favors. After loading up your device with music, the next thing to do is replace the headphones. Of course, if you're not absurdly picky about audio quality, we can understand not wanting to spend $100 or more on a new pair. That's where options such as the Creative EP-630 come in. These sound-isolating earphones offer a comfortable fit and improved audio for just $39.99.
