Hollyland Solidcom C1 Pro-4S
Featuring dual-mic Environmental Noise Cancellation (ENC) for use in noisy environments, the Hollyland Solidcom C1 Pro-4S is a full-duplex wireless DECT intercom system designed for clear audio and all-day wearing comfort in a true-wireless design without a bodypack or hub. This configuration includes 2 single-sided headsets, 1 master and 1 remote, along with rechargeable batteries, a charger and accessories. The system transmits in the 1.9 GHz spectrum and uses proven DECT 6.0 technology to ensure secure and reliable transmission at a line-of-sight range of up to 335 m - making it well-suited for a variety of applications including film/TV production, concerts and live events.
Dual-Mic noise suppression
For clear communication in noisy environments, use the dual-mic ambient 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 clearer speech intelligibility. The microphone’s wide 150Hz to 7kHz frequency response ensures detailed voice pickup so your team can stay on task.
The LED indicates that the system is working, with different colors representing different operating states. The blue LED is on to indicate that ENC squelch is on. The green LED is on to indicate that ENC squelch is off. The red LED is on to indicate that the microphone is off.
True-Wireless headset for 2-way communication
Without a beltpack or base station, the C1 Pro offers a highly portable and hands-free coordination experience for media production teams and others seeking real-time voice communications at line-of-sight distances of up to 1,000 feet (335 m). The Pro version offers greater portability and durability than the original, while the single-ear headset design is dust and water resistant and designed for comfortable all-day wear.
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°, allowing you to wear it on your left or right ear. 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 + charging station
Each headset is powered by one rechargeable battery. Battery life in the master headset depends on the number of linked headsets; with 1 to 5 remote headsets connected and ENC enabled, battery life is approximately 5 hours; with up to 7 linked headsets, battery life is 4 hours. Each remote headset will last up to 10 hours on a single charge with ENC enabled. Each battery is fully charged in 2.5 hours and a charging cradle, USB cable and AC adapter are included.
Improved portability and durability for a better experience
The Solidcom C1 Pro headset is made of PC-ABS materials, making it incredibly light - only 170 grams with the battery included and super compact. The improved leather over-ear cushion better matches the human ear structure for added stability and comfort, perfect for those working in demanding environments. Durable on-ear foam cushions are also provided for different wearing preferences. Use them as needed and enjoy the experience of incredible portability and comfort without compromising quality.
Effective prevention of wind noise
Are you bothered by wind noise in outdoor production environments? The Solidcom C1 Pro offers a versatile solution that prevents airflow from hitting the microphone directly. With the Y5 felt paper designed for the main microphone as a wind filter and the microphone cushion, the headset can reduce wind noise by 20.76 dB. You can enjoy complete peace of mind in production environments where wind noise is a big challenge.
Expandable and backwards compatible
The Solidcom C1 Pro system allows you to pair up to 7 remote headsets to the master headset without using a hub. With the C1 Pro HUB Base (sold separately) you can use up to 8 remote headsets simultaneously. The C1 Pro is backwards compatible with the Solidcom C1 system. Note that ENC technology works by removing ambient noise on the speaker side. Whether you are wearing a C1 or a C1 Pro, the ambient noise you hear is significantly reduced as long as the sound comes from a C1 Pro headset.
