Sony has expanded its Walkman series of portable players with the release of the Walkman E580 and E380 models. Slipping easily into a pocket, Walkman E Series keeps you entertained with generous battery life and powerful sound through sony's Clear Audio technologies.

Filling Walkman with your music collection is easy. Just drag and drop songs, photos, videos, podcasts and playlists (non-DRM content only) from Windows Explorer or your iTunes library.

Giving up to 77 hours play time from a single battery charge, the Walkman E580 features the ClearAudio+ mode along with a full range of Sony audio technologies to enhance your listening, including Clear Bass, Clear Stereo and Clear Phase. DSEE (Digital Sound Enhancement Engine) restores those subtle high frequency details that get lost when you?re listening to heavily-compressed digital music files. Unique to Sony, VPT (Virtualphones Technology) adds an extra dimension to your listening with the ambience of a studio, club or arena.

The supplied in-ear phones support the digital noise cancelling feature, designed to cut background sounds by up to 98%.

For the first time, E Series Walkman now lets you enjoy music files in the popular FLAC format.

The E380 Series is an introduction to legendary Walkman sound for younger music lovers. It supports Clear Bass along with a Dynamic Normaliser, which reduces unexpected jumps in volume between tracks when you?re listening in shuffle mode. There?s also a 5-band equaliser with presets and custom settings.

Photos and videos can be viewed on the LCD screen and of course, an FM radio tuner is included. The E380 video MP3 player offers up to 30 hours music playback from a single charge.

The players from Sony are available in Europe from July.
