Hollyland Solicom C1 Pro 4S DH 4-Person Noise Cancelling Headset Intercom (Double-Ear Version)

The Hollyland Solidcom C1-PRO-4S-DH is a full-duplex wireless DECT-powered intercom system that uses dual-mic ENC technology to drastically reduce on-site noise providing highly intelligible voice transmission in loud environments. The comfortable, dual-ear, lightweight stereo headsets feature a pair of microphones that work together to capture voice and noise. The result is fed to the ENC (Environmental Noise Cancelling) algorithm, which cancels the noise much the same way audio plugins remove specific instruments or vocals from a stereo signal. You get crystal-clear audio without the noise. Plus, integrated Acoustic Echo Cancellation removes echo between 150Hz to 7kHz. With 5kHz being approximately the target range of the human voice, this is extremely effective in delivering clear speech transmission in critical situations. Simple and easy to use, the C1-Pro has been engineered with a true-wireless design, meaning no bodypack or hub is required. The system includes 4 dual-ear headsets (1 Master and 3 Remote) and requires no extensive setup. Turn the headset on, place it on your head, and speak. To switch between talk and mute, simply press the talk/mute button or flip the boom up or down. Thanks to DECT 6.0 encryption and dual antenna technology, you'll enjoy secure and reliable transmission with a range of up to 1,100 ft. Clear communication when you need it most, the Solidcom C1-PRO-4S.
