Walkman: A História Ilustrada (1979–2004) A timeline of Sony’s cassette Walkman models from 1979 to 2004 - EP.23 - 1991: SONY WALKMAN WM-EX90

 

Released in 1991, the WM-EX90 was built for stationary use, aimed at study and practice rather

 segments with adjustable intervals. A built-in LCD displayed a digital counter, clock, and battery

 status.
