There's no doubt that the earbuds that come packaged with the majority of MP3 players are subpar in both fit and sound quality, but it's tough to drop more cash on a new pair to go with a just-purchased device. The good news is that there are options that won't cost you a cent over $20. One such example are the new Auvio Pearl Buds, a colorful set of earbuds that will set you back only $15. Auvio is Radio Shack's latest foray into the earphone market, and the Pearl Buds represent the bottom of the line. It shows. Sound quality is merely passable and the superthin cable is practically begging to break, but these buds are still a step up from stock, especially in the bass department. They could be worth it for those on an incredibly tight budget.
