The story of personal audio equipment begins in the late 1800s, shortly after the invention of the telephone and the loudspeaker. Businessmen recognized that with these technologies, live music could be shared with people far away from a concert hall. However, loudspeakers in public places can be an annoyance, which is still the case today.
This problem led to the invention of the Electrophone system by a British company. The Electrophone used telephone lines to deliver live performances from theaters and opera houses across London. The Electrophone service was a subscription-based model where subscribers rented special listening devices similar to doctors’ stethoscopes. They were made up of two earpieces which connect together below the chin. Since the service provided a novel form of entertainment, it was popular among the wealthy at the time.
