What Earmark does

Earmark (legal name: EARMARK; also doing business as EARMARK Radio Communications Systems and Earmark Communications) is a privately-held U.S. hardware manufacturer of specialized wireless communications equipment, founded in 1973 and headquartered at 515 Fan Hill Road, Monroe, Connecticut. The company designs and produces headset radios, full-duplex wireless systems, and communications equipment engineered for integration with respiratory protection apparatus (such as SCBA masks), enabling hands-free voice communication for workers in noisy, hazardous, and protective-equipment-restricted environments.

The company's product portfolio spans language laboratories and simultaneous translation systems (its original 1973 focus), headset radios, duplex wireless systems, and SCBA-compatible communications gear. Earmark primarily serves the construction industry, with secondary exposure to language and educational institutions, and applies a direct sales model (phone at 203-777-2130 and email at [email protected]) for both equipment sales and ongoing repairs. Pricing is not publicly disclosed. Earmark operates as a wholly-owned subsidiary of Redco Audio Inc., and on May 6, 2026 announced it will permanently shut down operations while continuing to offer repair services on existing equipment.
