While Blaster turns into a radio (that even functioned in Microchange), Soundwave turns into a microcassette recorder. Blaster plays sound-- Soundwave records it. Additionally, the tapes are microcassettes too, and are 1/4th the size of regular audio cassettes.
Soundwave just gets misremembered as "a boombox" as kids don't really have much common access to microcassette recorders.
