WM-F22

The WM-F22 is a standard AM/FM stereo radio Walkman that combined cassette playback and manual tuning in a familiar, mid-sized plastic body powered by two AA batteries. It supports normal and chrome/metal tapes but keeps the overall control layout simple, with no Dolby, no auto-reverse, and no recording functions. This model is clearly designed as a practical all-in-one listening portable rather than a more specialized branch.

The WM-F22 comes from a point when the radio Walkman had settled into the middle of the range as something normal and repeatable. Sony no longer needed to justify why a listener might want both radio and tape in one device. By 1985, that idea was already stable enough to support solid, everyday models like this.
