PC Magazine have published a review of the RCA S2501 Jet Stream MP3 player. 'RCA's new S2501 Jet Stream is geared toward gymgoers and offers a wireless listening experience, but it doesn't use Bluetooth to achieve it. The new technology, from Kleer, operates between 2,400 MHz and 2,480 MHz and sounds much better than Bluetooth 2.0 audio (which, frankly, isn't hard to do), but the earbuds that come with the Jet Stream, while providing decent range, are uncomfortable and don't fit securely in your ears, spoiling the audio quality. Throw in a tiny 1GB of storage, a dismal interface, and limited video- and photo-viewing capabilities, and you've got a player that disappoints in the gym—and everywhere else.'
