Sony NW-A810

The NW-A810/800 MP3 players have been critically praised for their audio quality, mostly due to its patented Sony technologies such as DSEE (Digital Sound Enhancement Engine) and Clear Stereo.

DSEE is claimed to restore higher sound frequency lost when creating compressed MP3 files, to reproduce the CD audio quality.

Walkman NW-A810 received great acclaim from CNET, which gave the gadget the Editor's Choice Award with a score of 8.0 out of 10, and was rated as "excellent".

Crave, the CNET gadget blog, named the NW-A810 series as one of the MP3 players that shaped year 2007, with another three, the Zune 80, iPod Touch, and the ZEN.
