This is a Sony voice recorder. I am selling it because I no longer use it. I will also include a microphone and a dedicated pouch, which were purchased separately. I feel that the recording quality is somewhat clearer with the microphone attached. - Brand: SONY - Capacity: 1GB (287 hours of recording possible) - Features: USB connection - Battery: AAA x 1 *Batteries not included I have confirmed that recording and playback are possible using commercially available AAA batteries, as it does not use rechargeable batteries. There may be minor scratches due to use. It will be shipped via Yu-Packet Post Mini. Thank you.
