The Hollyland Solidcom C1 Pro-4S is a complete, ready-to-deploy intercom system bundling 1 master headset and 3 remote single-ear headsets Hollyland's first wireless intercom platform with built-in dual-mic Environmental Noise Cancellation (ENC). A directional main microphone isolates the wearer's voice while a secondary omnidirectional mic samples ambient sound, letting the system actively cancel out background noise on loud sets, concerts, and outdoor shoots.
Built on advanced DECT 6.0 technology with dual-antenna diversity, the Pro-4S delivers a reliable line-of-sight communication range of up to 1,100 ft (350 m) and a wideband 150 Hz-7 kHz frequency response for clear, full-bodied speech. Encryption built into the DECT link keeps team conversations private from outside listeners.
True-wireless and self-contained, the system needs no beltpacks or base station to operate the master headset's transceiver links directly to all three remote headsets right out of the box. Wind noise gets specific attention via Y5 felt-paper filtering on each mic, and the headsets remain fully backward compatible with the original Solidcom C1 line, so they can mix into existing fleets.
Each headset includes a spare, swappable lithium battery for round-the-clock operation: roughly 10 hours per charge on remote headsets, and 5-6 hours on the master headset depending on how many remotes are connected. The kit ships complete with batteries and a charger, and the system can be expanded up to 8 headsets without a HUB, or to 9 with one. Ideal for church productions, TV and film sets, and live events that need clear, noise-cancelled team communication.
