☆ This is a listing for a SONY MD WALKMAN WZ-E30. ☆ Operation has been confirmed, but sound only comes from one side of the earphones. The part beyond the remote control is removable, so I think it will work if you replace it, but I will list it as partially defective. ☆ One battery and a charger are included, and charging was possible. However, I don't know how long the battery will last. Please consider it as a bonus since it's old. ☆ The AA battery pack has been tested and works, so I think you can still use it with AA batteries. ☆ There are some minor scratches, so please refrain from purchasing if you are sensitive to this. ☆ We plan to ship via Yu-Packet Post.
