WM-EX666

The WM-EX666 is a style-driven EX-series Walkman that reused much of the same logic-controlled playback platform as the EX511 but reframed it through coordinated color, accessories, and presentation. It retained auto-reverse, Dolby B, Extended DBB, AVLS, Automatic Music Sensor, blank skip, and remote operation, while adding matching earbuds, a color-coordinated remote, and a dedicated pouch that made the player feel closer to a personal carry item than a neutral electronics product. The includes charger and slightly longer runtime helped keep it practical beneath the styling emphasis.

This is one of those models where Sony was clearly treating the Walkman as part of a user's visible everyday identity instead of just a sound device. The EX666 matters less because of what it changed internally and more because of how directly it shows the cassette Walkman entering fashion-adjacent territory. It feels very much like a 1994 object: useful, familiar, and intentionally styled to be chosen as much as uses.
