SONY CD Walkman D-E660. Color: SILVER [Product Features] ・Built-in G-Protection, so there will be no sound skipping or playback stopping even if you tap the body with your finger during CD playback. ＊G-Protection explanation: Audio data from the CD is stored in semiconductor memory for several tens of seconds in advance.
