The Hollyland Solidcom C1-2S is a full-duplex wireless DECT intercom system engineered to provide clear audio and all-day wearing comfort in a true-wireless design with no bodypack or hub required. This configuration includes 2 single-sided headsets, 1 master and 1 remote unit, along with rechargeable batteries, a charger, and accessories. The system uses DECT 6.0 encryption and dual antenna technology to ensure secure and reliable transmission at a range of up to 1000'—making it well suited for a variety of applications including film production, concerts, and public events.

True-Wireless Self-Contained Headset for 2-Way Communication
With no beltpack or base station, the C1 offers a highly portable and hands-free coordinating experience for media production teams and others looking for real-time, non-blocking voice communication in socially distanced working scenarios at distances up to 1000'.

Enhanced Stability and Security with DECT 6.0
Built on the powerful DECT 6.0 platform and featuring a dual-antenna diversity scheme, the Solidcom C1 can prevent people outside the system from hearing your conversation with encryption technology and provides stable and reliable transmission with doubled user capacity on the communication channel.

Wide Frequency Response for Precise Coordination
The Solidcom C1 offers a 150 Hz to 7 kHz frequency response and premium acoustic echo cancellation (AEC) to ensure clear intelligible audio for effective teamwork. The directional mic captures the speaker's voice precisely while minimizing unwanted background sound, making conversations easier even in noisy environments.

Ready to Use Right Out of the Box
The headsets pair up automatically, and tactile volume buttons allow for fast adjustments—making the system easy to operate. The microphone boom on each headset rotates 360°, allowing for left or right orientation. Rotating the boom arm up or down conveniently mutes the mic when not in use. An LED indicates the system is working and warns you when the battery is low.
Rechargeable Batteries + Charging Station
Each headset runs on a single rechargeable battery. The amount of battery time in the master headset depends on the number of following headsets in use; with 5 remote headsets connected, the battery will last for approximately 5 hours; with 3 following headsets in use, the battery life is 6 hours. Each remote headset will last for up to 10 hours on a single battery charge. Each battery fully recharges in 2.5 hours and a battery charging station, USB cable, and AC adapter are included.
