1986 WM-35: The Floating Sports Walkman

The WM-35 was built around one defining idea: it could float. Its large, air-filled shell provided buoyancy, but it made the player feel light and bulky compared to earlier Sports models. The mechanism was intentionally simple, with single-direction playback and no Dolby noise reduction. It was not a daily workhorse so much as a statement that Sony was willing to reshape the Walkman for new environments.

1985 WM-F75: The Radio-Equipped Sports Walkman.

The WM-F75 added a full AM/FM radio to the WM-75 platform, and you can see the changes in the body. A rear bulge housed the AM ferrite antenna, and the internals were rearranged to make room for the tuner. The tuning scale ran along the edge of the cassette door, linked to a rear tuning wheel, and the indicators expanded beyond basic battery status. To keep the radio controls sealed, Sony dropped the second headphone jack.

1985 WM-75: The Compact Sports Walkman

The WM-75 refined the original Sports Walkman idea into a more compact, everyday package. It kept a serious mechanism and feature set, with Dolby B, metal tape support, switchable auto-reverse, and dual headphone outputs. Sealing dictated the layout, pushing the battery and secondary switches inside the cassette bay. Even the porthole window was functional, with a raised rim and studs that protected the face when set down.
