Sony is preparing three new Walkman series for tomorrow’s IFA 2008 event — the S, E, and B series. Let’s talk about the S series first. At just 7.5mm thick, the player is loaded with a bunch of high-end, format-friendly features, including the ability to play music from different sources, a handy preinstalled Content Transfer software, and support for popular multimedia codecs, such as WMV (DRM), WAV, and obviously, MP3.

To make things even better, Sony loads the S-series Walkman with Sony’s SensMe Channels function which automatically creates channels that can align with a user’s preferences. Based on Sony’s SensMe Channels function, the S-series players analyze a user’s music collection and suggest channels based on each song’s speed, mood and rhythm. They create a choice of 11 themed channels from upbeat pop to emotional ballads. Pretty cool, isn’t it? FYI, S-series is the first MP3 player with this kind of unique feature.

Other features include an in-flight noise cancellation for convenient music playback during flight, a high-contrast 2-inch QVGA display, up to 40 hours of music playback, up to 10 hours of video playback, and personalizeable interface with up to 10 pre-installed wallpaper images (users can also use their own photo as a wallpaper if they want).

Sony Walkman S series MP3 player is currently available in two different capacity variants: the NWZ-S736F (4GB) and NWZ-S738F (8GB). Both available in black color with price respectively set at $150 and $180.
