Among the MP3 players, Sony MP3 players give the highest sound quality due to advanced Audio codecs. I bought this player since it was a value for money and also capable of playing MP3 files and also video files, though the screen size is pretty small. It has been a good companion for me during my long travels across India.
The battery backup is very good and requires occasional charging only. Gives long hours of play.
It has various sound modes like Rock, Jazz, Pop etc for user preferred settings.
It can even store & display photographs.
