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.
I bought a set of 4x Eartec UltraLITEs a few years ago and returned them ASAP. That made me skeptical of these. But they are everything the Eartecs aren't: comfy, easy to use, effective, and high-quality. The audio clarity is amazing. The simplicity of pairing and muting/unmuting. The headsets are adjustable and comfortable. The kit even comes with so many extras: spare batteries, replacement foams, etc.
Planning to buy an extra remote headset or two soon. Everyone on my productions wants to get in on the comms!
Great for High School Theatre!

We ordered this set to use in our Theatre. They are great, easy to use and have a great range. Any of the options will work well based on your tech needs. We opted to use the set with 1 master headset. I give this one to our Stage Manager and all tech feed off that one. They are clear, easy to operate and can be used right out of the box. Our set came with extra batteries and all accessories to make each one fit comfortably. I love that there are extra batteries, cause in live theatre anything can happen. We look forward to using these for our future productions.

Does the C1 have restrictions when it comes to USA only vs abroad like the Eartec? If I can use this in and out of US that'd be sick!

The Hollyland Solidcom C1-4S Full-Duplex Wireless DECT Intercom System with 4 Headsets should be capable of operating in any country that allows and allocates space for wireless applications in the 1.9GHz frequency spectrum. The biggest compatibility hurdle may be adapting the power connections and voltage appropriately based on the local power source available.
