This is a blue 16GB Sony Walkman NW-A105. I've used it for about three years. Therefore, I'm not sure of the exact figures, but the battery drains quickly. The exterior has no noticeable scratches or stains because I used a case. Please understand that this is a used item. Instant purchase is welcome. Price negotiations are also possible. *Includes the main unit, instruction manual, charger, and USB cable. Nothing else is included. It has been initialized.
