Brandes had its origins as a Canadian company founded in Toronto in 1908. Shortly after these headphones were made, Brandes would then become a part of AT&T in 1922, with a British subsidiary named "Brandes Ltd." established two years later in Slough, Berkshire. They would later go on to produce a variety of loudspeakers as well. After the American parent company merged with the Kolster Radio Corporation (based in Newark, New Jersey), they would be known as Kolster-Brandes Ltd. and continue to supply bakelite cabinet radios. During their time in the industry, they made mid-range electronics such as radios, tape recorders, televisions, amplifiers and gramophones.
