The Sound Burger (marketed in the USA as the Mister Disc) was a portable record player that was launched in 1983 by Audio-Technica as their answer to the Sony Walkman – but for vinyl records.
The battery-powered turntable was designed to be used away from home and came with a set of fold-away headphones. It could play both 33 RPM and 45 RPM records.
The cassette and Walkman were a more obvious choice for portability due to their size and durability (you could walk or run with them), which quickly made the Sound Burger more of a novelty than a practical competitor.
Audio-Technica produced a limited-edition (7,000 units) revival model in 2022 to celebrate the company’s 60th anniversary.
