Dual-Mic Environmental Noise Cancellation (ENC)

The C1 Pro uses a dual-microphone ENC system to improve speech clarity in noisy environments. The algorithm combines a main directional microphone positioned near the speaker’s mouth with a secondary omnidirectional environmental microphone on the earcup. As a result, the headset cancels out unwanted background noise and prioritizes the speaker’s voice. The microphone captures a wide frequency range—150 Hz to 7 kHz—so voices remain detailed and intelligible during communication.

True-Wireless, Self-Contained Design

This headset operates without a beltpack or external hub when paired directly with a compatible master headset, giving teams a truly wireless and portable intercom option. The single-ear design supports all-day wear and offers dust- and water-resistant construction for use on film sets, concerts, and live events. The Pro model improves portability and durability compared with the original C1 remote headset.

Reliable Wireless Transmission

The system transmits in the 1.9 GHz band and uses proven DECT 6.0 technology for secure and stable audio links. In ideal, line-of-sight conditions, the C1 Pro supports two-way operation at distances up to 1100'. This makes the headset suitable for a variety of production scenarios where clear, real-time voice communication matters.

Simple Operation and Flexible Controls

Pairing is quick: press and hold the A button on both master and remote headsets and they will link in about 10 seconds. The microphone boom rotates 360°, so you can position it for left- or right-side use. Rotating the boom up or down mutes the mic, and the earcup mute button can be configured as either a persistent mute or a push-to-talk (PTT) control depending on your workflow. An LED provides status information and warns when battery levels are low.

Rechargeable Batteries and Runtime

The headset runs on a single rechargeable lithium-ion battery. With ENC engaged, a single battery provides up to 10 hours of operation. Each battery fully recharges in approximately 2.5 hours. The package includes two rechargeable batteries so you can swap cells for continuous use during long shifts.

Expandable and Backward Compatible System

You can expand a Solidcom C1 Pro setup without adding a hub by linking up to seven remote headsets to a single master headset. If you add the optional C1 Pro HUB Base, the system supports up to eight remote headsets. The C1 Pro remote headset is backward compatible with the original Solidcom C1 system. Note that ENC processing occurs on the speaker side: when a C1 Pro headset transmits, the environmental noise at that speaker is reduced, which improves the clarity heard by others on the system.

Frequently Asked Questions

Question: Can I use this remote headset without a master headset?
Answer: The C1 Pro remote headset is sold without a master and requires pairing with a Solidcom C1 or C1 Pro master headset (or a compatible hub) for two-way communication. It can, however, be used to expand an existing system by adding additional remote headsets when paired to a master.

Question: How long will a battery last during a typical shift?
Answer: With ENC engaged, each rechargeable lithium-ion battery provides up to 10 hours of runtime. Because two batteries are included, you can swap batteries to maintain continuous operation during long days.

Question: Will the ENC make it harder to hear environmental cues from the set or stage?
Answer: ENC focuses on reducing environmental noise on the speaker’s transmitted audio so others hear clearer speech. It does not remove all ambient sound from what you personally hear; the primary effect is clearer voice transmission from the person wearing the C1 Pro headset.

Question: How do I mute the microphone quickly on set?
Answer: You have two convenient mute options: rotate the boom arm up or down to mute the mic mechanically, or use the earcup mute button which can be configured as either a persistent mute or a push-to-talk function, depending on your preference.

Question: How many remotes can I connect to a single master?
Answer: Without a hub, you can link up to seven remote headsets to one master headset. If you add the C1 Pro HUB Base, the system supports up to eight remote headsets simultaneously.
