WM-A602

The WM-A602 is a compact playback Walkman built around the WM-150 auto-reverse mechanism, combining one-touch convenience with a slim metal-framed body and a more pocketable late-1980s silhouette. It includes Mega Bass and Dolby B noise reduction, along with a manual tape selector and carry clip, all powered by a single AA or gumstick-style battery arrangement that kept the machine compact and light. The controls and body proportions clearly favored everyday portability over display or experimentation.

A602 stands out more for the way it sits within Sony's growing confidence in the "compact but complete" playback Walkman by the end of the 1980s. It was not a flagship or a novelty branch, but a very resolved everyday machine for people who wanted uninterrupted listening and a little more sonic polish without carrying something bulky. It reads as late-1980s cassette maturity in compact form.
