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

The Hollyland Solidcom C1 Pro-4S is a full-duplex wireless DECT intercom system with four headsets and dual-mic Environmental Noise Cancellation (ENC) on the interference-resistant 1.9GHz band. It lets a team talk hands-free and simultaneously across a line-of-sight range of up to 350m (1100ft) while ENC strips out background noise, making it ideal for loud sets, live events and broadcast environments.

Key Features

• Dual-Mic ENC: Environmental Noise Cancellation uses a directional main mic and an omnidirectional noise mic to cut roughly 20dB of ambient noise for clearer voice.
• Full-Duplex Communication: Every member can speak and listen at the same time with no push-to-talk, keeping conversation natural and instant.
• Hub-Optional Operation: Works hub-free out of the case and can also connect to a HUB base to scale the network when needed.
• 1.9GHz DECT: Encrypted DECT transmission on the 1.9GHz band avoids the crowded Wi-Fi spectrum for stable, secure audio up to 350m (1100ft) line-of-sight.
• Clear HD Audio: A 150Hz to 7kHz response with a signal-to-noise ratio of around 71dB and under 1% distortion delivers clean, intelligible speech.
• Lightweight Comfort: Each headset weighs about 170g with battery for all-day wear.
