Summary: Having tried Sansa MP3s and IPods, I was hoping to have a better audiobook experience with this Sony. The audio quality is fine, the bluetooth headset works well, but the odd arrangement with the cord and the need to have a cheap plastic cover for the controls on the bluetooth, show some rather poor engineering and detract from a pleasant user experience.
Summary: I bought this to download mp3 files from NPR radio programs and listen to them. My complaint and it is a big on for me is that the volume is poor. I have hearing aids with bluetooth capability and they are fine listening to phone conversations in an automobile but I can only hear the Walkman in a quiet room. I would not by it again.
