Creative Zen X-Fi

Zen X-Fi is the first digital media player to be built with Creative’s X-Fi technology. Comes in 16GB or 32GB models with up to 36hrs audio playtime or 5hrs video playtime. Equipped with wireless capability, you can stream and download digital content wirelessly from your PC to your ZEN X-Fi within a home network and stay connected with friends on Yahoo Messenger or MSN Messenger.
The built-in X-Fi technology is supposed to intelligently moves a conventional left/right earphone stereo source away from your ears, virtually expanding it for an audio experience with a breathtakingly realistic depth of field. You’ll feel as if you were listening to your music from a pair of high end speakers.
