Olympus Digital Voice Recorder. I bought this DVR over a year ago to record lectures for learning purposes. I found the quality of its recordings to be excellent. It is light and small - about the size of your standard mobile phone, is easy to operate and can record 20 hours or more of voice recordings. It has three playback speeds, built in mic, and sockets for earphone (earphones did not come with it). It works with 2 AAA batteries. DVR is in excellent operating condition. (I have the operating instructions that go with it.)
