Founded in 1931 in Mayfair by Alexander Poliakoff, the company was known for high-quality tube hearing aids, even Winston Churchill was among their customers. Today Multitone is part of Kantone Holdings, a member of the Champion Technology group of companies, currently they're manufacturing wireless voice and messaging systems.

In the post-war years Multitone, which became Multitone Electronics plc, became a pioneer in the development of pagers (bleepers). From the 1970s they were exported all over the world. Poliakoff retired in 1977 and sold Multitone to a Hong Kong-based telepaging group, Champion Technology.
