The headphone converts into sound the electrical impulses caused when the circuit is completed in the contact chamber of the current meter. The headphone consists of a single earphone with a headband and a soft, plastic-covered rubber ear cushion. The system is powered by an AA 1.5-volt battery. A 4 foot (1.2 meter) long, two-wire electrical cord leads from the headphone battery case to a standard connector.
