This is a rare and stylish vintage Sony Walkman NW-E013 USB Mini MP3 player in a striking metallic pink colour (although the box says pink, it is closer to purple in my opinion). It has a colour LCD display which was quite rare for this era. This model of Walkman was only produced for a short time so they are pretty rare and are becoming quite collectible.
The headphones are missing but all of the other original items (including the software CD) are in the box.
Sold for repair because the internal rechargeable battery does not hold a charge so it cannot be used until this is replaced. Years ago I may have attempted this but age has caught up with me so my eyes and hands are no longer able to work on such small and fiddly items.
