The Hollyland Solidcom C1 Pro-6S Full-Duplex Wireless Intercom System with 6 Headsets (1.9 GHz) is a wireless intercom system designed for use in noisy environments. It features dual-mic Environmental Noise Cancellation technology for clear audio and all-day wearing comfort. This Hollyland Solidcom C1 Pro-6S Full-Duplex Wireless (6 Pack) includes 6 single-sided headsets, a master and 5 remotes, rechargeable batteries, a charger, and accessories. The system operates in the 1.9 GHz spectrum and uses DECT 6.0 technology for secure and reliable transmission up to 1100' range. It is suitable for film/TV production, concerts, and live events. No bodypack or hub is required for this true-wireless design.

Dual-Mic Environmental Noise Cancellation

For clear communication in loud environments, engage the dual-mic ENC (Environmental Noise Cancellation) feature. The ENC algorithm combines the main directional microphone at the speaker's mouth with a secondary omnidirectional environmental mic on the earcup to cancel out unwanted background noise for more intelligible speech. The microphone's wide 150 Hz to 7 kHz frequency response ensures detailed voice capture to keep your team working efficiently.

True-Wireless Self-Contained Headset for 2-Way Communication

With no beltpack or base station, the C1 Pro offers a highly portable and hands-free coordinating experience for media production teams and others looking for real-time voice communication at line-of-sight distances up to 1100'. The Pro version offers increased portability and durability over the original, while the single-ear headset design is dust and water resistant and designed to provide a comfortable all-day wearing experience.

Easy to Use

A long press on the "A" button on the master and remote headsets is all it takes; the headsets pair up in about 10 seconds and you're good to go. 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. Alternatively, the mute button on the earcup can be set to mute or push to talk, depending on the user's preference. 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 1 to 5 remote headsets connected and the ENC features engaged, the battery will last for approximately 5 hours; with up to 7 following headsets in use, the battery life is 4 hours. Each remote headset will last for up to 10 hours on a single battery charge with the ENC engaged. Each battery fully recharges in 2.5 hours and a battery charging station, USB cable, and AC adapter are included.

Expandable and Backwards Compatible

The Solidcom C1 Pro system allows you to link up to 7 remote headsets to the master headset without using a hub. The C1 Pro HUB Base (available separately) lets you use up to 8 remote headsets at once. The C1 Pro is backward-compatible with the Solidcom C1 system. Note that the ENC technology functions by removing the environmental noise at the speaker side. Whether you're wearing a C1 or a C1 Pro, the environmental noise you hear will be significantly reduced as long as the sound is coming from a C1 Pro headset.
