The Fernwellen-Apparatebau AG sets the tone in the 20s - with TELAKU radio parts.

In the early days of radio, the main unit still had to be connected to a separate headphone or funnel loudspeaker for sound output. The original founder Johannes Kohler sensed a promising business idea here and began to develop and produce double-headphones and loudspeakers as well as detectors to be built into radios.

The headphones on display are one of the first products manufactured by FABAG (Fernwellen-Apparatebau AG). Like all radio parts, they are marketed under the „TELAKU“ brand.
