WM-FX77

The WM-FX77 is an advanced radio Walkman from Sony's 1991 FX line, combining cassette playback with the World Wide Twin Tuner system that stored separate FM/AM/TV preset sets for domestic and travel use. That dual-memory approach let users move between regions without overwriting their familiar station setup, while the rest of the machine retained Sony's late-period cassette essentials: auto-reverse, EX Amorphous head, Extended Dynamic Bass Boost, AMS, AVLS, Sound Swing Guard, and a hold shutter paired with a wired LCD remote. Quick-charge support and the compact metal body kept it firmly in the premium everyday category.

What set the FX77 feel distinctly 1991 apart was that Sony was no longer simply adding radio, but trying to solve the little behavioral annoyances that comes with using radio seriously. This is less a "feature-packed" model than a very considered one, built around the assumption that people actually lived with these devices and moved between routines. It falls in that mature phase where the Walkman had become less of a novelty object and more of a portable system people depended on.
