Founded in 1968 in San Francisco by audio engineer Charlie Butten and sound company owner Bob Cohen, Clear-Com is a manufacturer of professional intercom and real-time communication systems. The company originated with the RS-100, a portable party-line intercom beltpack that used XLR cables — a design that became the industry standard for backstage and crew communications in live production. Now headquartered in Carlsbad, California, and operating as a subsidiary of HME, Clear-Com serves broadcast, live performance, military, government, and sports markets worldwide.

Clear-Com's product line spans analog and digital partyline intercoms, digital matrix systems, wireless intercoms, and IP-based communication platforms. Key products include the Eclipse HX digital matrix system, the FreeSpeak and FreeSpeak II wireless beltpack intercoms, the HelixNet digital partyline system (built on a multi-channel wired digital intercom technology patented in 2009), and the Arcadia IP-based platform. The company received a Technology and Engineering Emmy Award in 2010 for its contributions to broadcast communication technology. Clear-Com intercoms are a fixture in television studios, theatrical productions, concert tours, and major sporting events, where reliable crew communication is essential.

Clear-Com has 5 products cataloged on Equipboard, including Headphones & In-Ear Monitors.
