The Sony 4GB W Series Walkman MP3 Player (Black) offers an innovative all-in-one design for enjoying your music while working out. The cordless headphones house a 4GB MP3 player and come with three different size earbuds for optimum comfort. The one-piece design features a unique band that floats comfortably on the back of your neck, allowing you to be wire-free, hands-free, and without distraction whether you're at the gym or outdoors working out. The W Series Walkman is also water-resistant with a IPx5 rating, which means that it will hold up to even the most intense workouts
If your forget to charge the device before a run, a three-minute quick charge will give you up to 60 minutes of playback, while a full 1.5 hour charge will give you up to eight hours of playback. The MP3 player is also equipped with Sony's exclusive Clear Audio Technologies, as well as the ZAPPIN search feature, which lets you navigate through your music collection by playing back main melodies.
The Walkman is compatible with Windows XP (SP2), XP (SP3), Vista, and Windows 7. Plus, for added convenience, the player lets you drag and drop your audio files from iTunes for Windows, Windows Media Player or Internet Explorer. Once your files are loaded onto the Walkman, you can change songs with a tap of the Rocker Switch on the headphones, and to change folders or playlists, just tap and hold the switch.
