Walkman: A História Ilustrada (1979–2004) A timeline of Sony’s cassette Walkman models from 1979 to 2004 - EP.11 - 1984: SONY WALKMAN WM-F5

 

Launched in 1984, the WM-F5 became the first Sports Walkman. Its yellow, impact-resistant

 shell used splash-proof sealing and rubberized controls, allowing brief immersion. It paired that

 rugged build with the Disc Drive mechanism and added an FM radio for outdoor use.
