DESC: The new improved eXpanium 201 has a smaller size, new design, and a bigger display to make portable MP3 playback even better than before. You will be able to read your MP3 tracks on the larger display as you play CDs that can hold over 10 hours of music. The EXP201 is ultra-portable: it can play up to 15 hours on four AA batteries and includes a set of stereo headphones. No more listening to MP3s at the computer - now you can listen to them wherever you are.
