Despite being a fairly early model, the WM-10 was the smallest of all the cassette-playing Walkman models. Its tiny size is amazing even now, and represents a considerable achievement in the context of what was possible in the early 80’s. The WM-10 was smaller even than the cassette it played and had to be slid open to make the cassette compartment large enough to take the tape.
