WM-F55

The WM-F55 is a stereo radio Walkman that integrated an AM/FM tuner into the same basic platform as the non-radio WM-55, while keeping auto-reverse playback and Dolby B noise reduction. It uses the same anti-rolling mechanism, runs on two AA batteries, and keeps radio operation simple through manual tuning and a straightforward band selector. The overall design stays compact and practical, avoiding the extra bulk or sealing complexity of the Sports radio models.

This model fits the kind of product Sony handled well by the mid-1980s: not especially flashy, but tuned to the everyday realities of how people actually listened. For users who wanted both cassettes and live radio without paying for ruggedization or recording features, the F55 made more sense than the more specialized branches around it. It is a classic daily-use Walkman in the best sense.
