Before the Walkman, music was a shared thing. You heard it through a room โ€” a speaker, a crowd, a car radio everyone agreed on.
Sony TPS-L2 shipped July 1, 1979. ยฅ33,000 in Tokyo. Two headphone jacks. No record button. That was the point.

Card 03 โ€” Era Tokyo, 1980. For the first time, the soundtrack was yours alone.
Masaru Ibuka, Sony's co-founder, wanted something to listen to on long-haul flights. His engineers had four weeks. The two headphone jacks were a hedge โ€” Sony executives didn't believe anyone would listen alone.
They were wrong. Within a year, Sony had sold over a million units. The category they called "personal stereo" hadn't existed before July 1979.
The MDR-3L2 headphones that came in the box were orange. People wore them outside. Publicly. That was new.
What's the first album you remember hearing on headphones, fully alone?
