Excellent Condition Rare SONY Walkman WM-F707 Manual Power was briefly confirmed, but functionality is unknown. However, it appears to have been very well cared for, with no scratches or damage, and is in excellent condition. The microphone wire is slightly discolored in one area, but otherwise it's in good shape. It might work if you replace the battery with a new lithium battery. Since I don't know, I'm selling it as junk.
