Hollyland Solidcom C1 Air 6S 1.9 GHz Wireless Intercom System

Hollyland Solidcom C1 Air 6S 1.9 GHz Wireless Intercom System

The Hollyland Solidcom C1 Air 6S Wireless Intercom System is a six-user, full-duplex production communication package built around five ultralight C1 Air remote headsets and one Solidcom C1 Pro master headset. It provides hands-free 1.9 GHz communication for production crews without requiring separate beltpacks or a conventional base station.

This configuration is designed for film sets, live streaming, broadcast production, commercial shoots, and event crews that need continuous team communication while moving around a venue. Each C1 Air remote headset weighs approximately 1.5 oz and uses an open-ear OWS design that reduces the pressure and heat associated with conventional closed-ear headsets. Dual-microphone environmental noise cancellation helps prioritize speech when operators are working around production noise.

The included Solidcom C1 Pro master headset provides the central wireless connection for the five C1 Air remotes and incorporates DECT-based full-duplex communication. The C1 Air remotes are designed for integration with the existing Solidcom C1 ecosystem, while the C1 Pro master provides wideband audio, ENC processing, replaceable battery power, and a portable self-contained format. The package also includes dedicated batteries, a six-slot charging base, headset accessories, and a carrying case for field deployment.
