IRiver IFP-590

iRiver Japan continue their never-ending innovation with the new iFP-500 series models. In addition to the now-familiar features like direct MP3 encoding, FM radio and voice recording, iRiver raise the level with the addition of optical output and mic input! Voice recording through either the built-in mic or an external microphone can be activated by the sound input level to conserve memory during moments of silence...perfect for capturing all of those long lectures you'd like to nap through. The iFP-590 has 256MB of memory and a fantastic 28 hours of playback battery time, enough to get you through a whole week of bus or train rides.
