WM-17

The WM-17 was a budget cassette Walkman introduced in 1984, combining colorful plastic construction with a more useful feature set than its price might suggest, including auto-reverse playback and Dolby B noise reduction. Beneath the outer shell it used a metal internal frame, ran on two AA batteries, and included a manual tape-type selector with straightforward transport controls arranged for easy everyday use. It was not a compact flagship or specialist model, but a simple player built to make the Walkman experience accessible without stripping away too much convenience.

By 1984 Sony no longer needed every Walkman to prove a concept. Models like the WM-17 filled out the lower end of the range for buyers who wanted something reliable and modern without paying for miniaturization or prestige. It comes from the phase when the Walkman was becoming less a novelty and more a normal personal possession, the kind of machine someone bought simply because they needed one.
