Hollyland Solidcom C1 Pro-4S-DH

The Hollyland Solidcom C1 Pro 4-Person Noise-Cancelling Headset Intercom is a dual-mic Environmental Noise Cancellation (ENC), full-duplex wireless DECT intercom system for use in loud environments and with all-day wearing comfort. It has a true wireless design with no bodypack or hub for use.

The system comes with four dual-ear headsets (one master and three remote), eight rechargeable batteries, an 8-bay charger and several crucial accessories. The system transmits in the 1.9 GHz spectrum and uses proven DECT 6.0 technology to ensure safe and reliable two-way transmission with a line-of-sight range of up to 335 m with a wide frequency response for clear sound. The package also comes with a carrying case for protection and transportation of your equipment.

Dual-Mic Ambient Noise Cancellation

For clear communication in noisy environments, use the dual-mic Environmental Noise Cancellation (ENC) feature. The ENC algorithm combines the main directional microphone at the speaker’s mouth with a secondary omnidirectional ambient microphone on the ear cup to suppress unwanted background noise for better speech intelligibility. The microphone’s wide 150Hz to 7kHz frequency response ensures detailed voice pickup so your team can stay on task.

True-Wireless standalone headset for 2-way communication

Without a beltpack, the C1 Pro offers a highly portable and hands-free coordination experience for media production teams and others seeking real-time voice communication at line-of-sight distances of up to 335 m. The Pro version offers greater portability and durability than the original, while the dual-ear headset design is dust and water resistant and designed for a comfortable all-day wearing experience.

Easy to use

A long press of the A button on the master and remote headsets is all it takes; the headsets pair in about 10 seconds and you’re good to go. The boom arm on each headset can rotate 360 degrees, allowing you to position it left or right. Rotating the boom arm up or down conveniently mutes the microphone 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 that the system is working and warns when the battery is low.

Rechargeable batteries

The master headset is powered by one rechargeable lithium-ion battery. Battery life depends on the number of subsequent headsets in use; with one to five external headsets connected and ENC functions enabled, battery life is approximately five hours; with up to seven external headsets in use, battery life is four hours. Each battery is fully charged in approximately two and a half hours. Eight batteries are included with this system.

Expandable and backward compatible

The Solidcom C1 Pro system allows you to pair up to seven remote headsets (sold separately) to the master headset without using a hub. With the C1 Pro HUB Base (sold separately) you can use up to eight remote headsets simultaneously. The C1 Pro master headset is backwards compatible with the Solidcom C1 system. Note that the ENC technology works by removing ambient noise on the speaker side.
