Here is the SONY Net Md Walkman compact disk player/recorder. The unit is in very good condition and works. I used my earbuds for this playback of included compact disk and it sounded great. This runs on single AA 1.5vt battery. (!) I played around with it a little. You can find (Google) and download a manual for it. I played the disk by the group "Opie Gone Bad"--live at Red Rocks. It is very good rock music. I don't know who these guys ...are but I like them. Maybe a rare recording, who knows. Comes with battery only. I think this item was made around 2000 or so. A very nice scarce player for your collection or use it................................................
