WM-EX110

The WM-EX110 is part of the plainest EX-series cassette players of the mid-1990s, built around a standing plastic body with cassette window, belt clip, manual tape selector, and Sony's two-position Auto Volume Limiter System. It uses a simple playback-only transport powered by two AA batteries, with counter-rotating flywheels helping keep tape motion stable without adding more visible complexity. There was no auto-reverse, Dolby, or bass enhancement to dress the machine up beyond its most basic purpose.

A model like this only starts to matter once you stop looking for famous ones. The EX110 sits in the phase where Sony was still defending the bottom of the cassette market against generic competition by keeping a very basic branded player in circulation.
