This is a Sony portable MD recorder. *Please note that recording is not possible.* SONY Model: MZ-B100 DIGITAL MEGA BASS Operates on one AA battery *Battery not included* Battery life (using alkaline batteries): Approximately 15.0 hours Size: 107.6 x 81.2 x 25.7mm Weight (body only): 160g Playback speed adjustment: Approximately +10% to -20% Purchased new. Used as a recorder for work. There are no noticeable scratches or stains, and the appearance is in good condition. No battery leakage. Unfortunately, the record button does not work properly, so the recording function is unusable. Playback function via speaker/earphones and remote control function work without problems. Editing functions such as deleting songs also work without problems. I think it can still be used as an MD player with a speaker. The instruction manual has stains on the cover, small holes, and creases. I will sell this to someone who understands that it is a used item and can only play back. - Main unit - Remote control (almost unused) - Earphones (almost unused) - Instruction manual - Strap (slightly used as it was always attached) *Batteries are not included* *No outer box* #Sony #MD #Portable player #Rare
