The Hollyland Solidcom C1 Pro Wired Headset is equipped with dual-mic Environmental Noise Cancellation (ENC) feature, making it suitable for use in noisy environments. It can be connected to the hub (available separately) through a 10-pin LEMO connector, serving as the primary headset in this full-duplex wireless DECT intercom system. The system can accommodate up to 9 users simultaneously, and additional hubs can be daisy-chained to accommodate more headsets, allowing for further expansion.
