On July 1, 1979, Sony put a stereo in your pocket and quietly rewired how the world listens.

Verified · Victoria and Albert Museum — Stowaway TPS-L2 personal stereo

On July 1, 1979, Sony began selling the TPS-L2 in Japan, a blue-and-silver, metal-cased cassette player it called the Walkman. It had no speaker and no record button, just headphones and play, which sounded absurd until you tried it. The point was not recording music but carrying it, privately, anywhere.

The machine grew out of co-founder Masaru Ibuka’s wish for something small enough to play music on long flights. Engineers stripped a portable recorder down to playback and added lightweight headphones.

“The world’s first low-cost portable stereo.”

Sony expected modest sales and braced for a flop. Instead the Walkman sold out, spawned a verb, and turned the daily commute into a private soundtrack. The V&A in London now keeps one as the first-ever portable stereo. Every set of earbuds since is, in spirit, its descendant, and the cassette hiss is the only thing we left behind.
