Radio hat

A radio hat is a novelty headwear item incorporating a radio receiver, and often a speaker, directly into the design of a hat. Popular primarily in the 1930s and 1940s, radio hats allowed wearers to listen to radio broadcasts without the need for a separate radio set and headphones. Typically powered by batteries concealed within the hat's structure, these devices were marketed as a symbol of modern convenience and technological ingenuity. While the concept saw a brief resurgence in later decades with different technologies, the original radio hat remains a distinct artifact of early portable electronics.
