Hollyland Solidcom C1 Pro-4S Full-Duplex ENC Wireless Intercom System

Wireless Intercom System for Seamless Team Communication
The Hollyland Solidcom C1 Pro-4S is a full-duplex wireless DECT intercom system designed to provide hands-free, real-time communication for teams working in live events, film production, and broadcasting. Featuring a completely wireless design, this system eliminates the need for bodypacks or base stations, offering increased mobility and convenience. With four single-ear headsets—one master and three remotes—it ensures clear, interference-free voice transmission up to 1,100 feet, making it an ideal choice for professionals who require reliable, high-quality communication.

Dual-Microphone Environmental Noise Cancellation for Clear Audio
The Solidcom C1 Pro-4S integrates advanced dual-mic Environmental Noise Cancellation (ENC) technology, which effectively reduces background noise while maintaining voice clarity. By using a secondary omnidirectional mic on the earcup alongside the main directional mic, the system filters out ambient sound to deliver crisp and intelligible speech. With a wide 150 Hz to 7 kHz frequency response, the audio remains detailed, ensuring smooth and effective team coordination even in noisy environments.

LED Status Indicators for Easy Monitoring
This system features intuitive LED indicators that provide instant feedback on the headset’s status. A steady blue LED signifies that ENC noise reduction is active, while a steady green LED indicates that ENC is off. A steady red LED shows when the microphone is muted. These indicators allow users to quickly assess their headset’s operational state, making adjustments simple and efficient during live productions.

True Wireless Design for Maximum Mobility
Designed for professional use, the Solidcom C1 Pro-4S offers a lightweight, wireless experience with no need for additional packs or wires. The comfortable single-ear headsets are water- and dust-resistant, making them durable enough for extended wear in demanding conditions. The 360° rotating boom microphone allows users to wear the headset on either ear, while muting the mic is as easy as flipping the boom up or pressing the dedicated mute button.

Quick Setup with Simple Pairing Process
Setting up the system takes only seconds. A long press on the “A” button of the master and remote headsets initiates pairing, which completes in approximately 10 seconds. Once connected, users can immediately begin communicating with clear, full-duplex audio. This intuitive pairing process reduces downtime and ensures teams can focus on their tasks without technical interruptions.

Long Battery Life with Convenient Charging Station
Each headset operates on a rechargeable lithium-ion battery, with runtime varying based on system use. The master headset lasts up to five hours when connected to one to five remote headsets with ENC enabled, or around four hours when connected to seven remote units. Remote headsets provide up to 10 hours of continuous use. Each battery fully recharges in just 2.5 hours using the included multi-bay charging station, USB cable, and AC adapter, ensuring minimal downtime between shifts.

Durable, Lightweight Design for Extended Use
Constructed with high-quality PC-ABS materials, the Solidcom C1 Pro headsets weigh just 6 ounces (170g) including the battery, making them comfortable for all-day use. The over-ear leather cushions offer a secure and ergonomic fit, while additional on-ear foam cushions are included for those who prefer a different wearing experience. Built for professionals working in fast-paced environments, this headset delivers comfort, durability, and outstanding audio performance.

Wind Noise Reduction for Outdoor Use
Wind noise can be a major issue in outdoor productions, but the Solidcom C1 Pro-4S provides a robust solution. Each headset’s main microphone is equipped with Y5 felt paper as a wind filter, along with a microphone cushion that reduces wind noise by 20.76dB. This ensures clear voice transmission even in challenging weather conditions, allowing teams to communicate effectively in any setting.

Expandable and Backward-Compatible for Larger Teams
This system is fully expandable, allowing up to seven remote headsets to be linked to the master unit without requiring a hub. For larger teams, the separately available C1 Pro HUB Base supports up to eight remote headsets. Additionally, the C1 Pro is backward-compatible with the original Solidcom C1, making it easy to integrate new and existing units within a communication network.
