Apple iPod Shuffle ( 2012, red)
The Apple iPod Shuffle is an adorable way to take your favorite songs on the go, but sometimes it's too small for its own good.
SanDisk Sansa Clip Zip ( grey, 8GB)
SanDisk's tongue-twister of an MP3 player is a stupefying value and its practical clip-on design is perfect for the gym.
SanDisk Sansa Fuze+ MP3 ( black, 4GB)
You can find smaller or cheaper MP3 players, but you won't find a better value than the Sansa Fuze+ in terms of dollars per features.
Apple iPod Shuffle 2011 ( 2GB, silver)
The iPod Shuffle's buttons are back, and the lightest, smallest MP3 player on the planet is now better than ever.
Apple iPod Shuffle ( third generation, 2GB, pink)
The third-generation iPod Shuffle is the next best thing to an invisible MP3 player, but the quirky controls and microscopic design make it a limited recommendation.
iRiver LPlayer ( 4GB, pink)
The Iriver LPlayer is a pint-size version of the well-received Clix. You get most of the same features in a smaller package offered at a pared-down price point.
Zune ( second generation, 4GB, red)
The 4GB and 8GB capacity Zunes (Zune 4 and Zune 8) offer a bite-size version of their full-size, 80GB sibling. While the full-size Zune is a better value, the solid-state flash memory used in the 4GB and 8GB versions make them better suited for physically active (or clumsy) users.
Samsung U3 ( 2GB, pink)
The Samsung U3 is the proof that a basic MP3 player doesn't have to be ugly and featureless; it's simple, inexpensive, cool-looking, and perfect for the gym.
RCA Jet S2001 ( 1GB, yellow)
If you're looking for an inexpensive MP3 player for the gym, the RCA Jet--FM tuner, armband, stopwatch, and all--is a solid choice, but the interface will take some getting used to.
SanDisk Sansa Connect
The Sansa Connect is a nicely designed player with desirable features and advanced wireless technology, making it a great choice for early adopters and Yahoo Music Unlimited subscribers. With a bit of tweaking to the integrated Wi-Fi, this device could become a "must-have" music player for users who want fresh content all the time.
