The SanDisk Sansa c250 is able to play MP3, WMA, WAV, and protected WMA DRM (digital rights management) music files. The screen on the c250 can exhibit up to 64,000 colors, and lets you choose to display album cover art for the current song via ID3 tag support, or photo thumbnails that you have downloaded to your player. The Sansa supports JPEG, TIFF, PNG, BMP, and GIF as import media types, and lets you create a slideshow out of your downloaded pictures, allowing you to tell a wordless story. The intuitive interface makes sorting through and playing back music a snap, while the built-in digital FM tuner lets you not only listen to new music via the radio, but 20 programmable presets let you identify your favorite radio stations and cycle between them with the press of a button. And as if that weren't enough, SanDisk's Sansa c250 also lets you record FM radio on the fly so you can save favorite programs for later, and since this unit includes a built-in microphone, you have the capacity to record external audio as well for when you want that clip from a concert, or you need to be able to go back and listen to parts of a presentation or lecture at a later date.

The Sansa c250 MP3 player has two gigabytes of built-in flash memory that allows you to store up to 500 songs (16 hours of playback) in 128 kpbs MP3 format, or up to 1,000 songs (32 hours of playback) via the WMA's 64 kbps encoding level. This unit supports subscription music stores so you can easily purchase and download new music to your player, and features a digital equalizer that has five presets, including normal, rock, jazz, classic, and pop, as well as one customizable equalizer setting. The c250 uses a high-speed USB 2.0 connection for fast file transfers from your computer, and includes a MicroSD slot for reading MicroSD cards with additional content on them, effectively expanding your memory capacity infinitely. This player also features a hold switch that prevents any accidental operation or changes in settings during transit.

The rechargeable lithium-ion battery that comes with this MP3 player allows for hours and hours of music playtime before needing to be recharged, and is removable so you can always buy a spare in case you are going on an extra long trip where you won't have consistent access to power outlets. The c250 requires Windows XP with SP1, Windows Media Player 10 or greater, a CD-ROM drive, and an open USB 2.0 port in order to take full advantage of all its features. The SDMX7-2048 Sansa c250 comes in a stylish black that not only looks good, but makes you look good with it, and is backed by a manufacturer's limited 1-year warranty.
