WM-GX312

The WM-GX312 is a practical radio-recording Walkman from Sony's GX line, built around utility instead of refinement. It combined cassette playback and recording with a manual FM stereo / AM / TV tuner and a built-in speaker, making it more versatile in ordinary note-taking or casual desktop use than most slimmer playback-only models. Auto-reverse, Extended Dynamic Bass Boost, AVLS, and cue/review functions were present, but Dolby noise reduction and more advanced search features were left out in favor of a simpler, more durable everyday design.

This is the kind of machine that reminds you how much of the cassette market was still built around ordinary tasks instead of collector-friendly premium hardware. The GX312 makes sense for people who needed to record notes, listen back without headphones, or keep one compact portable around for mixed use at home and on the move. It is modest, but very clear about what it was for.
