Thank you for viewing. Recording, playback, and deletion have been confirmed using the built-in microphone. FM/AM reception and recording are also OK. The FM antenna uses the earphones. External memory is recognized for both MicroSD and M2. The item for sale is the main unit only, and external memory and earphones are not included. A micro USB cable and a charger such as a smartphone charger are required for charging, so please prepare them yourself. The exterior is in beautiful condition with little sign of use. Thank you for your consideration.
