SIRIUS helped transform the way we listen to radio, and now they're transforming the way we listen to SIRIUS itself with the S50 satellite radio/MP3 player, a wildly innovative blend of features that'll make your listening experience more rewarding. When docked in its cradle, it plays live SIRIUS broadcasts, captures SIRIUS content, and lets you store and listen to your favorite MP3 or WMA files. With its included accessories, you can play it over your car stereo, or take it with you and listen wherever you go. The S50's internal memory lets you store up to 50 hours of SIRIUS content or up to 512 megabytes of your MP3/WMA files — or you can combine some of each.
