SONY MZ-R910 Portable MD Player with G-Protection This is an older model. The exterior appears to be in good condition with no major scratches. Playback functionality has been confirmed. It comes with a rechargeable battery, but its remaining playback time is unknown due to its age. Playback is also possible with AA batteries using the dry cell adapter. It has a recording function for MDs, but the recording operation has not been tested. A microphone that I used in the past is included (operation not confirmed). No instruction manual is included. - Brand: SONY - Model Name: MZ-R910 - Accessories: Microphone, cable, pouch, AC adapter, rechargeable battery, dry cell case - Features: G-Protection - Type: Portable MD Player
