Thank you for viewing. This is a wireless neck speaker made by JBL. [Note] This is the main unit only, without a transmitter. Please be careful not to make a mistake. There is slight yellowing (around the neck: photo 3), some discoloration (resin part: photo 10), and the resin part connecting the USB terminal cover and the main unit is cut (photo 11), so please purchase only if you don't mind. [Operation Check] Charging has been confirmed. It has been confirmed that music can be played by connecting to a computer. [History] I purchased it about 6 years ago for 15,800 yen and used it for about 2 years, then stored it in a box for 4 years. [Accessories] The box and accessories such as the charging cable are all included (photo 8).
