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.
Comfortable to Wear All Day Long
Each headset weighs less than 6 oz, which is lighter than many common smartphones. It can bring you a comfortable experience even if you wear it for a long time. You will not feel tired at all because of wearing it for a long time. Solidcom C1 headsets are crafted from PC-ABS material, which guarantees excellent flexibility and durability. Each headset is equipped with replaceable ear cushion. On-ear foams and over-ear cushions are provided for different wearing preferences. Easy to replace and free to share.
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.
Expandable System
With its recent firmware upgrade, the Solidcom C1 system allows you to link up to 7 remote headsets to the master headset without using a hub. The C1 HUB base (available separately) allows up to 8 headsets to be used at once. Up to 3 hubs can be cascaded with a standard RJ45 cable, allowing for up to 24 headsets to be used at the same time. The HUB also offers additional features including A/B grouping and an announce key that mutes all the headsets for emergency messages from the HUB base.

Will we be able to use this C-1 set within range ...

Will we be able to use this C-1 set within range of a Eartec UL35 UltraLite headset system, or will there be interference between the two systems?
Asked by: Gwen
Yes, the Hollyland Solidcom C1-2S Full-Duplex Wireless DECT Intercom System can be used within a 1000' operating range of the Eartec UL3S UltraLITE 3-Person Headset System without interference. When initially setting up the two systems all components should be off. Turn on power for the components in the first system and allow them to pair. Then leave the first system with the power on and turn on power for the components in the second system so they can pair to a different frequency which will allow the two systems to operate independently.

What is the difference between this and Solidcom M1 and how heavy is the headset ?
Asked by: Senoga
The Hollyland Solidcom C1-8S Full-Duplex Wireless DECT Intercom System implements a more sensitive electret microphone in its headsets and does not work as well in loud environments as the dynamic microphone in the Solidcom M1 headsets. The C1 system also performs all functions through its headsets and eliminates the need for belt packs, where the M1 utilizes headsets tied to belt packs. The C1 system is expandable from 2 to 9 users, where the M1 is offered in 4 and 8 user configurations.
