Hollyland Solidcom C1 Pro-4S-DH Full-Duplex ENC Dual Ear Wireless Intercom System

Crystal-Clear Comms in the Eye of the Storm

The Hollyland Solidcom C1 Pro-4S-DH is the ultimate full-duplex wireless intercom solution for crews who refuse to let environmental noise dictate their workflow. Specifically engineered for broadcast teams, concert roadies, film production crews, and house of worship technicians, this 4-person system offers total hands-free mobility without the clutter of bodypacks or external hubs. With its double-ear design, your team stays locked into the conversation, ensuring every cue is heard with surgical precision, even in the loudest arenas.

Communication is only as good as what you can actually hear. The Solidcom C1 Pro features a first-of-its-kind dual-mic Environmental Noise Cancellation (ENC) technology. By utilizing a directional main microphone and an omnidirectional secondary mic to sample background noise, an advanced algorithm cancels out the roar of the crowd or wind interference. This allows your team to speak at normal conversational volumes while delivering crystal-clear 150Hz–7kHz wideband audio to the rest of the crew.

Say goodbye to snagged cables and heavy beltpacks. The C1 Pro is a true-wireless system where the transceiver is built directly into the headset. Workflow is further streamlined by the intuitive Talk/Mute button with PTT (Push-to-Talk) functionality and the signature auto-muting mic boom—simply flip the boom up to silence your feed instantly. Whether you are coordinating a live broadcast or a complex stage production, the 350m (1,100ft) line-of-sight range ensures you stay connected across the entire venue.

Crafted from high-grade PC-ABS materials, each headset weighs a mere 170g, making them comfortable enough for 12-hour shifts. The double-ear version features upgraded over-ear leather cushions that fit the human ear structure for superior sound isolation and stability. With each system including spare batteries and a multi-slot charging case, you can swap power in seconds and maintain a continuous 10-hour runtime per charge.
