The BSSP07 from Buffalo is a new series of stereo speakers that you can use with MP3 players, mobile phones, or iPods. They aren’t much to look at, but they do the job and are available in four different colors.
The speaker will give you up to 800mWatt x 2ch, which should be enough for use in any small room. The Buffalo BSSP07 requires four AA batteries or a spare USB port to operate. Nothing on pricing just yet, but it shouldn’t cause you too much pain.
