It is a high-end Walkman NW-WM1Z made by SONY. I used to use it when commuting, and the usage time is around 150 hours. There are no scratches or stains, and the condition of the battery etc. is very good. Please see below for details. ◆ About the condition There are no scratches, dirt, or poor contact. When using it, I put it in a DIGNIS leather case and a vannize carrying case, and also used the attached cap for the earphone jack and WM-PORT part.
