WM-EX66

The WM-EX66 is a playback-only EX-series Walkman from 1992 that combined Sony's mature cassette essentials with a more colorful, everyday-facing presentation. It uses an EX Amorphous head, auto-reverse transport, Automatic Music Sensor track search, AVLS volume limiting, and Sound Swing Guard anti-vibration control, with a centrally placed rotating hold dial that made the control layout feel more integrated than on many earlier models. Vivid body finishes helped distinguish it visually from plainer siblings, while the wired remote preserved the increasingly standard late-Walkman habit of controlling playback one step away from the main unit.

This model shows how settled the Walkman had become by the early 1990s. Sony was no longer trying to persuade buyers that cassette portability was exciting, but making sure even midrange players felt pleasant, stable, and current enough to remain desirable. The EX66 is a very deliberate everyday machine from a time when the basics had already been refined enough to feel mature.
