Hollyland Solidcom C1-4S (4-Person headset System)

1,000FT Full-Duplex Wireless Intercom Headset System
The Solidcom C1 full-duplex wireless intercom headset system, adopting the advanced DECT 6.0 technology, is Hollyland's first true wireless and self-contained headset communication solution with exceptional sound clarity. The system operates in the 1.9GHz band, providing a reliable transmission range up to 1000ft (350m) radius (LOS).

Effortless Conversation Flow
Hands-free operation maximizes team productivity.
Each headset is designed with a dual-antenna diversity scheme that reinforces anti-interference capability, guaranteeing secured and constant team communication in complex environments.

True Wireless Self-contained Headset Communication Solution
With no belt pack or base station, it offers a highly portable and hands-free coordinating experience for media production teams or any team looking for real-time non-blocking voice communication in socially distanced working scenarios.

Ready Out of Box, Easy to Use
The headsets will automatically connect up right out of the box. Power up to kick off your day.

Comfortable to Wear All Day Long
Each single headset weighs only 168g, which is lighter than an iPhone12, offering a comfortable wearing experience for long hours. The headset is exquisitely crafted with PC-ABS materials, guaranteeing outstanding flexibility and durability.

Replaceable Ear Cushions
On-ear foams and over-ear cushions are provided for different wearing preferences. Easy to replace and free to share.

Rechargeable & Replaceable Battery for Extended Working Time
Each intercom headset comes with a spare lithium battery for convenient field replacement, keeping systems up and running with minimal downtime.
The batteries are rechargeable externally by a dedicated multi-port charger. Each takes only 2.5h for a full charge that supports up to 10h runtime of a remote headset and 5h-6h runtime of a master headset depending on the number of remote headsets connected.

Wideband Clear Audio Quality for Precise Coordination
Supporting a Wideband frequency response from 150Hz to 7KHz and premium AEC (Acoustic Echo Cancellation) performance, the Solidcom C1 intercom headsets ensure authentic and clear audio quality for effective teamwork.
Equipped with a directional microphone that captures the speaker's voice precisely while minimizing unwanted noise, the system renders an effortless conversation experience even in noisy environments.

Stay Connected in 1000ft Coverage Zone
The transceiver built into the Solidcom C1 master headset creates a reliable wireless communication radius up to 1000ft. So your team can keep connected and move freely at a major event, filming site, or mass area operation. The Solidcom C1 HUB base provides the same scale coverage.

Enhanced Stability and Security with DECT 6.0
Built on the powerful DECT 6.0 platform, the Solidcom C1 can prevent people outside the system from hearing your conversation with employed Encryption technology; and provide excellent transmission stability with doubled user capacity on the communication channel.
