Purchased just after Christmas and I am delighted with the quality of the unit and sound reproduction particularly via my Sony bluetooth wireless speaker ie SRS-XB3.

I need a portable hi-res player in low-mid price range. This is the best find. It plays the hi-res music impeccably. The digital noice cancelling works wonder if you do not have a good headphones to play it with. The clear audio feature really does augmented the file to play in 'higher sound' than when I play it in another player. From sound pov (which is the most important), it is perfect. I do not give five star because of some 'minus' such as : the outdated screen, inavaibility of easier playing now playlist, and the ease to import the music. I found the division of internal and external memory importation to be annoying.

The only huge problem are the controls. Anything touches the Walkman and it turns on, in your bag all work day and then battery bars are used. If something touches the front panel, the songs go back to number one, that is painful. Great sound great excellent battery.
