I have a faint memory as a child of playing with the Radio Shack Armatron. I don't know the story of how my family came to own one of these, but my guess is that my dad (who liked gadgets as a young man) splurged on this for himself and eventually just let us play with it until it broke.
How amazing is this? Product placement crossovers were really at their peak in the '80s. This one featured the Burger King Whopper on a pair of AM radio headphones sold at Radio Shack in 1983. The headphones look pretty good actually but as LGR says below in the video, the sound was less than appealing.
The '80s and '90s are real hot right now. When will somebody re-make these with Bose inserts? I mean, c'mon, real Whopper size muffs this time though, ok?
