A Boombox - also known as ghetto blaster (since 1983), Jambox, Wogga box or (in parts of Europe) raio-cassette - is a name given to portable stereo systems capable of playing radio stations and recorded music (usually cassettes and/or, since the early 1990s, CDs), at relatively high volume. As befits its portability, Boomboxes can be powered by batteries as well as by line current.
