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.
LED shows that the system is working, with different colors representing different operating states. Blue LED is steady, indicating that ENC noise reduction is turned on. Green LED is steady, indicating that ENC noise reduction is turned off. Red LED is steady, indicating that the microphone is off.
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.
Increased Portability & Durability for a Better Experience
The Solidcom C1 Pro headset is crafted using PC-ABS materials, making it incredibly lightweight-a mere 170g (6oz) with the battery included and super compact. The upgraded over-ear leather cushion better fits the human ear structure for added stability and comfort, perfect for anyone who works in challenging environments. Durable on-ear foam cushions are also provided to address different wearing preferences. Simply use them as needed and enjoy the experience of incredible portability and comfort without compromising quality.
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, the headset can reduce wind noise by 20.76dB. You can enjoy complete peace of mind in production environments where wind noise is a major challenge.
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.
These surely changed the game in wireless comms a few years ago. When the C1 Pro was first released, I met the team from Hollyland on a US tour and they brought demos with them. Bought them the next day for my old venue and a first purchase for a new venue - highly recommended!

Hi, you would need to purchase two remote headsets as two master headsets cannot be paired with one another.

Asked by: jake
Yes. The Hollyland Solidcom C1 Pro system allows you to link up to 7 remote headsets to the master headset without using a hub. Adding the Hollyland Solidcom C1 Pro ENC Hub Base (B&H # HOHLC1PROHUB) lets you use up to 8 remote headsets at once. The Solidcom C1 Pro components are backward-compatible with the Solidcom C1 system, so you can use the C1 and C1 Pro headsets together.

Asked by: WISNER
Hollyland does not recommend using the Hollyland Solidcom C1 Pro-4S Full-Duplex ENC Wireless Intercom System with 4 Headsets (1.9 GHz) outside of North America because it is made to work according to frequency laws within North America. However, some folks have successfully used this system outside of North America and its efficiency in your intended region would ultimately depend on that region's wireless frequency laws.

Do the user headsets form a pseudo "mesh network" amongst themselves to add range when used with a base station?
Asked by: Josh
The operating range for the Hollyland Solidcom C1 Pro, with and without the hub base is 1100-feet. The Hub Base allows you to do A/B grouping of the headsets, connect to a computer for Skype and Zoom call functionality, 2- and 4-wire audio input/output, and cascading up to 2 other hub bases via an IP network, for a larger system. The hub base also as an 'Announce' button for emergencies, which allows you to mute all of the headsets, so that only the headset that is wired into the hub base can be heard in the rest of the headsets.

I actually have an 18 set system with 2 hubs I bought from b&h . they work effortlessly! I am surprised that even the hollyland response says otherwise. I have had them now for close to a year with no issues. I even use the A and B gruop feature on larger productions that require 2 teams.

Will this work over walls / 2 floors?
Will this work over walls / 2 floors?
Asked by: Daniel
Sorry but not. The walls will influence the transmission of wireless signals greatly. The wall's obstruction will reduce the Solidcom C1 wireless signal and communication performance. Thus, we do not recommend the user use the intercom device between walls.
