WM-FS221

The WM-FS221 is part of the last classic yellow Sports Walkman, released in 2001 with an emphasis on battery endurance and expanded radio coverage instead of on redesign for its own sake. It offers up to 32 hours of tape playback from two AA batteries, digital tuning with auto preset scanning, and reception across FM, AM, TV audio, and weather bands, all within a sealed ergonomic body that includes an action grip for outdoor use. The layout stayed direct and accessible despite the broader radio feature set.

This model works best as the closing stage of the original Sports idea. Sony was no longer inventing that identity by then, just refining it into something practical and familiar for the remaining users who still wanted a rugged cassette player. The FS221 is the end of a long branch that had already figured out what it needed to be.
