If you're looking for an inexpensive MP3 player for the gym, the RCA Jet--with FM tuner, armband, stopwatch, and all--is a solid choice, but the interface will take some getting used to.
Rubber flaps cover both the standard mini USB port and the headphone jack, preventing the player's insides from getting damaged. However, as you'll need to plug in the headphones during use, we're a bit skeptical about the usefulness of that flap.
The Jet's main control pad is straightforward, with a play/pause button surrounded by track shuttle keys and volume controls. However, the pad is stiff, making the buttons a bit difficult to press. Plus, there's a slight lag in the interface.
A menu button on the top of the player takes you to one of two top menus, depending whether you hit it once or twice. It would have made more sense if the player used one main menu, with several submenus, for navigation.
The RCA Jet offers a splash-proof, rubberized design and solid-state flash memory, making it ideal for those "not so dry" moments at the gym or during other active pursuits.
There's even a wrist strap for those who prefer to wear the device that way. RCA includes sporty clip-on earphones (not shown) to ensure that you get the most secure listening experience possible.
