The Sony NW-E005F Walkman is a member of Sony's latest entry-level line of flash-based MP3 players, the E000 series, intended for digital audio newbies. It's basically a USB thumb drive that plays digital music files with a built-in FM tuner and a one-line OLED screen. The player is relatively simple to use, and its small size and light weight make it perfect for exercising and casual listening. But its subpar audio quality, combined with a lack of on-the-go playlisting or PlaysForSure support, prevents me from recommending it to experienced listeners despite its low price.
