This looks like just a concept but a designer named Yong-Seong Kim designed this DAP that unfolds to play CDs and MP3 CDs. It looks cool but not very functional as you can’t just put it in your pocket or backpack when playing a CD. What it would be good for is if you go someplace to sit down and there’s CDs around like a library. Although it would be weird to just listen to a CD at the library without taking it home and ripping it to your computer.
