Hollyland Solidcom C1 Pro-4S Full-Duplex Wireless Intercom System with 4 Headsets (1.9 GHz)

Featuring dual-mic Environmental Noise Cancellation (ENC) for loud environments, the Hollyland Solidcom C1 Pro-4S is a full-duplex wireless intercom system designed for clear, real-time team communication. Operating in the 1.9 GHz spectrum and built on proven DECT 6.0 technology, it delivers secure and reliable transmission at up to 1100' (335 m) line-of-sight.

This kit includes 4 single-sided headsets (1 master + 3 followers) in a true-wireless design that requires no bodypack, base station, or hub. The dual-mic ENC algorithm combines a main directional mic at the mouth with a secondary environmental mic on the earcup to reduce background noise for more intelligible speech, while the wide 150 Hz to 7 kHz response supports detailed voice capture.

For fast operation, headsets pair quickly and can be muted via a dedicated Mute/PTT button or by rotating the mic boom. LED indicators show ENC and mic states. The system is expandable (up to 7 followers with the master without a hub; up to 8 followers with an optional hub) and is backward compatible with the Solidcom C1 system.
