1991 WM-SXF30: The Sports Walkman Goes Global

The WM-SXF30 marks the shift from experimentation to standardization. Based on the WM-BF59, it kept auto-reverse, AM/FM radio, and water resistance, but moved production to Taiwan and adopted a more modular build. A metal internal frame improved rigidity, and pressure-relief vents showed lessons learned about sealing. Nothing here was radical, and that was the point.
