WM-EX53

The WM-EX53 is a flatter, more compact EX-series playback Walkman that moved away from the upright budget format and into a more pocket-oriented laying design powered by a single AA battery. It offers auto-reverse playback, Dolby B noise reduction, Mega Bass, anti-rolling support, automatic music search, and logic-controlled transport in a body reinforced with metal elements and shaped to feel thinner and more deliberate than Sony's simpler two-AA models. Even without becoming luxurious, it was clearly a more resolved object.

By this point the EX line was starting to feel distinctly early-1990s. The EX53 was less about raw feature count than about how neatly everything was packaged together. It reads more as a machine built for people who already knew what a Walkman was and now wanted it to be slimmer, smoother, and easier to live with.
