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 3.5mm 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 cancelling capability of the Walkman. In addition Sony released their midrange E-series and entry-level B-series Walkman players.
