Altec Lansing inMotion® iM4 2 Speakers

These speakers aren't powerful enough to provide sound across the home, but they're great if you're just looking for speakers for a single room. They have a good sound, including enhanced bass, and it's easy to connect them to a variety of MP3 players. I was particularly impressed with the bass. It can be difficult to get reasonable bass sound in a set of inexpensive speakers.

The speakers have their own volume switch, but you can also use the equalizer on your MP3 player to adjust the sound quality.
