Sony's S-series Walkman is their new high-end digital audio player that is not only their slimmest player to date, but has active noise cancellation and the SensMe music suggestion engine. Sony bundled 13.5mm EX headphones with the S-series players, as well as a pass through cable that connects to an in-flight entertainment system and uses the noise canceling capability of the Walkman. In addition Sony released their midrange E-series and entry-level B-series Walkman players.
The S-series has a 2-inch QVGA screen, that not only plays back WMA, AAC and MP3 audio formats, but also WMV and MP4 video. SensMe is featured on a Walkman player for the first time, previously only on Sony Ericsson Walkman-branded phones. For those unfamiliar, the SensMe engine analyzes a song for various qualities and maps it on an X-Y chart. From there you can select what type of music you want to listen to according to "mood". The S-series is only 7.5mm thick, has 40 hours of audio playback and 10 hours of video playback on a single charge.
