This chart compares ultra-portable MP3 players. These players are often entry-level models, or designed to be purchased for a specific use like exercise by someone who already owns an MP3 player. They are distinguished by their very small size and light weight, making them perfect for something like exercise.

The iPod Shuffle is the iPod that fits this space in Apple's lineup. Like the iPod nano, these players use Flash memory to store data.

This chart is designed to make it easy to compare the features and prices of these players to guide your buying decision.

This chart does not compare hard-drive-based players or mid-range Flash-memory-based players.
