ICD-UX523 (Blue) ★USED★ This is a SONY IC recorder "ICD-UX523 (Blue)". ・Internal memory = 4GB (expandable with a separately sold micro SD card) Upon close inspection, there are some slight scratches on the LCD cover, etc., but I think it's in relatively good condition. Of course, there are no problems with its operation. The IC recorder body and the only included accessory are the gray dedicated pouch (cushion case) shown in the photo. Please prepare AAA batteries for use. I believe the original batteries were Cycle Energy, but I mainly used Eneloop (not included). It's a type that can be charged via the USB port (requires settings), and since you can also use spare batteries when using it for a long time, I personally found it more useful than recent models with built-in rechargeable batteries. It also operates on regular alkaline batteries, so please choose the batteries according to your needs. (However, charging is prohibited for batteries other than rechargeable ones.)
