Pump up the volume wherever you are--whether pounding the urban jungle pavement or power cycling at the gym--with Sony's NW-E103PS Network Walkman. Amazingly small and light, the round NW-E103PS measures just 2.21 inches in diameter and weighs under one ounce. It has a 256 MB internal flash memory and plays MP3, ATRAC, and ATRAC3plus formats. It's also compatible with content purchased and downloaded from Sony's Connect Music Store (available for Windows PC users only). This model comes in white, and is also available in black.

Originally developed for Sony's MiniDisc players, the ATRAC3 format increases the sound compression rate by approximately one-tenth, thereby reducing the file size and enabling you to store more music. ATRAC3plus goes even further, with compression levels of 1/20 the original sound source, but provides stronger sound quality than other formats and comparable compression levels. The 256 MB memory will store up to 170 songs, or over 11 hours (calculated at 4 minutes per song using ATRAC3plus compression at 48 kbps). Though it doesn't play WMA or WAV, these formats can be converted into either ATRAC3 or ATRAC3plus.

Because music is stored on internal flash memory--with no moving parts, like hard drive-based players--the NW-E103PS won't skip when jostled, making it the perfect workout partner. The NW-E103PS has a blue backlit LCD that provides song information (such as title, artist, album, etc.) and easy toggle navigation. It also includes a bass and treble equalizer.
