Hollyland Solidcom C1 Pro Full-Duplex ENC Wireless Intercom Master Headset (Single-Ear)

The Hollyland Solidcom C1 Pro Full-Duplex ENC Wireless Intercom Master Headset (Single-Ear) is the primary wireless coordinator and central transceiver brain of Hollyland’s premier intercom ecosystem.

Unlike standard remote units, this Master headset handles all local signal mixing and cryptographic routing right on your head—eliminating the need for an external base station or body belt-packs. It is tailored for directors, technical producers, and stage managers who need to coordinate teams in extremely loud environments.

Pro-Tier Audio & Routing Features

• Environmental Noise Cancellation (ENC): The standout feature of the Pro line is its active dual-microphone array. A directional main microphone captures your voice, while an omnidirectional secondary microphone on the outer earcup tracks ambient venue noise. An internal ENC processor strips away up to 20dB of low-frequency background din, ensuring your crew hears clear commands even if you are standing next to loud concert speaker arrays or rumbling venue generators.

• Versatile Push-to-Talk (PTT) Toggle: The earcup features a large, highly tactile physical button switch. The operator can click it to alternate between an open-mic "always-on" state, a standard "click-to-mute" loop, or a "hold-to-talk" function for quick, fast commands.

• Flip-to-Mute Mechanics: Features Hollyland’s signature mic boom ergonomics. Rotating the microphone boom arm vertically upward past a physical detent click instantly mutes your audio transmission. Swinging the arm down past your mouth immediately opens the channel back up.

• Backward Compatibility: The Master headset is fully backward-compatible with original, standard Solidcom C1 Remote Headsets. It will seamlessly mix older C1 signals into its network, though only the Pro headsets will transmit active noise-canceled audio back to the group.

System Capacity Constraints

Because the Master headset acts as the literal pillar of a hubless network, its operating scale is tightly defined:

• Ecosystem Limits: A standalone C1 Pro Master Headset can anchor a total team of up to 8 simultaneous users (1 Master Headset paired with up to 7 C1 Pro Remote Headsets) over an open full-duplex communication channel.

• Hardware Exclusivity: Remote headsets cannot communicate with each other if this Master headset is turned off, out of range, or missing from the field.

Technical Specifications Matrix

Ergonomics & Power Infrastructure

The headset chassis is built from lightweight, high-impact composite polymers, balancing the unit's weight at 170 grams—roughly equivalent to a modern smartphone. This ergonomic design significantly reduces neck strain and ear fatigue during grueling production schedules.

Because the Master unit is constantly transmitting and receiving signals across up to seven remote channels simultaneously, its battery expends energy faster than remote units, yielding 6 hours of runtime on a single cell. Helpfully, the headset features a built-in USB-C port directly on the earcup chassis. For extended shoots, you can run a standard portable power bank straight into the headset while actively wearing it, delivering continuous power without interrupting team communications.

On-Set Master Power Protocol: Since the Master headset acts as the backbone for your entire team, its power cycle is shorter than the 10-hour runtime of the remote units. When planning your shooting day, always designate the freshest, fully charged battery pack to the Master node during lunch breaks or turnarounds. Keeping the Master unit continuously powered prevents an accidental communication blackout across the rest of your crew's headsets.
