Sirius Satellite to Sell Portable Player

Sirius Satellite Radio Inc., the No. 2 U.S. pay-radio company, will begin selling its first portable device to compete with larger rival XM Satellite Radio Holdings Inc. and products such as the iPod.

The Sirius S50, which will be available for $359.99 in October, will store and play back as many as 50 hours of radio or music files, New York-based Sirius said. The device, about the size of a deck of cards, can be strapped on an arm or clipped to a belt.
