The Sony Walkman DD I have for sale is a portable cassette player that has been recently serviced and is 100% tested/working. It features a Hi-Fi Direct Drive, which is capable of producing high-quality sound from cassette tapes. Additionally, the device has a headphone jack, making it perfect for listening to music on the go. This device is for anyone who has a collection of cassette tapes and wants to enjoy them on a portable device with a lot of history and high reputation for competing with at-home deck playback performance.

I bought this here on eBay from a reputable seller. I live this tape deck. I have hundreds of tapes,  boom boxes, and 3 Nakamichi tape decks.

This was part of a loving home but unfortunately I need money for unexpected expenses.

This was mostly a display piece but I used it occasionally while out shopping for used tapes.

I bought this for $380 2 years ago here on eBay. Listing for what I paid.
