Walkman: A História Ilustrada (1979–2004) A timeline of Sony’s cassette Walkman models from 1979 to 2004 - EP.2 - 1982: SONY WALKMAN WM-5

 

Introduced in 1982, the WM-5 followed the WM-2 with nearly identical mechanics. Its pressed metal casing replaced plastic, making it smaller and more durable. The metal shell forced the volume control inside, with a small window added to show the setting.
