This is Sony's first generation Network Walkman model using memory stick. Comes with original packaging. Lion Battery died due to age however I found similar type of battery. Because I'm not good at soldering, I will give this new battery into the package and you can replace it by yourself. Without battery, walkman works via power adapter. Song recording via Sonic Stage and playing functions work well. You can check these tests on photos. Backlight still bright. It is a hard to find collection object for Walkman collectors especially with that condition. Warranty and returns are excluded.
