The look and grip are very nice, the overall dimensions are twice lower than the iPod Mini. It weighs 25 grams.
Of course here no color screen, no images but everything is for music and nothing but music and he does it very well.
The ATRAC audio format has much, personally I love classical music and very instrumental music (Jazz, etc.) and then this format restores rich sound all very far from MP3, WMA or other more suited to large low or email.
That said do not worry, it also supports these file formats to the recompressing.
The compression of an album takes 1 to 2 minutes and transfer the walkman about 30 seconds (USB2).
The supplied headphones are very good musically.
I leave you because with its mirror look and these 25 hours of reading this Walkman music still has a lot to me to discover.
