Today Sony announced the new Walkman E-Series video MP3 player, which features up to 50 hours of audio playback (mp3 files at 128 kbps) and 10 hours of video playback (WMV at 384 kbps). This new player also features 2 of Sony’s own technologies: Clear Audio and SenseMe. Clear Audio is an audio technology that offers clear, deep sound without distortion, while SenseMe automatically categorizes your music tracks in your library into a variety of music channels and playlists. There’s also a Bookmark Function that allows listeners to create on-the-fly playlists. The Sony E Series Walkman will be available next month for about $70 for a 4GB memory version and $80 for an 8 GB version at Sony Style.
