Boxed Sony NW-A55HN complete with USB charging cable and documentation. This is a Japanese version that DOES NOT INCLUDE THE EU VOLUME CAP and also has an FM RADIO.  I have switched the language to English.

These are remarkable little machines - I bought one about a year ago not knowing much about it - and was blown away. It contains a Bluetooth Receiver that can be used in 2 ways, either to connect to a bluetooth speaker to play. Or if you connect it to an ampllifier or plug in headphones then you can switch the Bluetooth to Receiver mode and connect your phone to it - the quality of the music through this thing is a huge step up from playing it directly from your phone. I use it out and about as well as to drive both my Car Stereo and Kitchen Stereo - even the wife commented that it sounded brilliant.
