This is a used item, but the battery hasn't deteriorated much as it wasn't used frequently. If you only play music at a constant volume without any extra operations, it will last for more than a day. *I think the manufacturer's description of 52 hours below is quite an exaggeration. As shown in the image, the item includes only the main unit, a speaker-equipped charger, and an adapter. There is no outer box. Please prepare a separate connection cable to connect the Walkman to a computer. Manufacturer's Description Compact body of approximately 53g with a long-lasting battery of 52 hours. Cuts out surrounding noise. Equipped with digital noise canceling function. Ideal for language learning, with effective functions such as "A-B repeat playback" to repeatedly listen to the parts you want to focus on, and "Quick Replay" to rewind the playback position.
