WM-F75
The WM-F75 is a Walkman with a built-in radio. It features Dolby B and auto-reverse, and uses AA batteries. It belongs to the early Walkman lineage that integrated radio functionality.
The idea of a rugged Walkman had started with the bright yellow WM-F5, but turning that concept into a practical, fully featured portable player required a more complete approach. The WM-F75 represented that shift.
It brought together weather resistance, radio reception, and cassette playback in a form built to handle movement rather than simply endure it. The sealed enclosure was refined with larger rubberized buttons, protected ports, and a rear housing shaped around a ferrite antenna for stable AM reception.
