Sony presented its new first walkman series the NW-A800.

The gadget has a screen of a 2-inch LCD (liquid crystal display) panel with QVGA resolution (240 pixels by 320 pixels).
Audio playback in a number of flavors of Sony's ATRAC compression is possible, and Sony supplies software for converting Windows Media Audio, MP3 and WAV files to ATRAC. For video the Walkman plays back MPEG4 H.264/AVC encoded files.

Playback time on a fully-charged battery differs depending on the type of files. For audio its roughly 30 hours for ATRAC files encoded at 132k bps (bits per second) while for video its seven hours for MPEG4 files encoded at 768k bps. Video files at lower bit rates will take up less space in the memory but also make the Walkman work a little harder on the decoding, so the time drops to about six hours and 30 minutes for a 384k-bps file, according to Sony's figures.

The Walkman measures 44 millimeters wide by 88mm high and is 9mm thick. It weighs 53 grams.
The NW-A805 is listed on Sony's online store for €180 (US$237), the NW-A806 for €230 and the NW-A808 for €300..
