Initially available in 512-megabyte (MB) and 1-gigabyte (GB) capacities, the SanDisk Sansa players can store hundreds of songs and play up to 15 continuous hours on a single AAA battery. The new players feature an SD card slot to conveniently add more storage capacity, which can be significant since SanDisk and other companies have recently announced SD cards up to 2GB in capacity.

The new players are designed to work seamlessly with a wide range of popular music formats such as MP3 and Windows Media Audio (WMA) in both unprotected and protected files (such as those WMA files purchased from music service provider sites).
The SanDisk Sansa music players include stereo headphones, carrying case with armband, USB 2.0 cable, AAA Battery and Install CD with value-added software. For added flexibility, they can be used as a USB storage device. Furthermore, the new industrial design was created with future accessory options in mind.
Additional features include:
- SD card slot for additional storage and convenient music transfer
- Hi-Speed USB 2.0 for fast music transfer speeds
- Support for MP3, WMA (both protected/DRM and unprotected)
- Up to 15 hours of continuous use with a single AAA battery
- Digital FM radio with 20-presets
- Multi-line Indiglo Backlit LCD that displays album, artist and song title information
The Digital Audio Players are "plug and play" with PCs due to USB Mass Storage Class (MSC) compliance when used with Windows XP, Windows 2000, Windows ME.
The SanDisk Digital Audio Player is expected to be available in March 2005 with suggested retail prices of $149 and $199 for the 512MB and 1GB models. They will be sold at many of the 93,000 stores worldwide where SanDisk sells its products.
