350m Full-Duplex ENC Wireless Intercom Headset System
The Solidcom C1 Pro, Hollyland's first-of-its-kind full-duplex wireless intercom headset system featuring dual-mic Environmental Noise Cancellation (ENC) technology, is incredibly lightweight and easy to use. It is a true game changer with built-in ENC, ideal for production teams working in loud environments where exceptional communication clarity is essential. This new-generation headset system features a wideband audio range of 150Hz to 7kHz, and a reliable LOS communication range of up to 1,100ft (350m).

ENC-powered Clear Audio for Efficient Team Coordination

Unparalleled Dual-Mic ENC
The Solidcom C1 Pro boasts unparalleled dual-mic ENC technology that delivers clear sound captured from challenging loud environments. Its directional main mic focuses precisely on the speaker's voice range, and simultaneously, the omnidirectional secondary mic collects environmental noise from different directions as noise samples. The sound signal is processed with the advanced ENC algorithm, effectively cancelling the environmental noise and delivering crystal-clear sound quality.
Note: The ENC technology functions by removing the environmental noise at the speaker side, so that the listener can hear the speaker's voice clearly.

150Hz–7kHz Wideband Audio with AEC
The Solidcom C1 Pro intercom system is capable of delivering authentic and clear sound even in the most demanding production environments. Its premium Acoustic Echo Cancellation (AEC) function effectively removes unwanted echo within the 150Hz to 7kHz frequency response range, bringing in more efficient teamwork.

Robust Wind Noise Removal
Troubled by wind noise in outdoor production environments? The Solidcom C1 Pro offers a versatile solution that prevents airflow from directly hitting the mic. With the Y5 felt paper designed for the main mic as the wind filter as well as the microphone cushion, you can enjoy complete peace of mind in production environments where wind noise is a major challenge.

Exceptional Simplicity for Efficiency
The Solidcom C1 Pro is ready when you are. The out-of-the-box and ready-to-go features redefine the wireless intercom system category, and its simple form factor design achieves a breadth of intuitive operations. Just switch the headset ON, place it on your head, and then begin talking with your team in a matter of seconds, so that you can focus more on efficient hands-free team collaboration.
