The Hollyland Solidcom C1-4S is a self-contained, full-duplex wireless intercom kit for 4-person crews, combining 1 master headset and 3 remote single-ear headsets with no beltpack or base station needed. The master headset's transceiver links directly to all three remotes, so the whole team can talk and listen at the same time straight out of the box.
Built on the DECT 6.0 platform with dual-antenna diversity for stable, secure transmission, the C1-4S provides a wireless communication radius of up to 1,000 ft (300 m). A 150 Hz-7 kHz wideband frequency response paired with Acoustic Echo Cancellation (AEC) keeps speech clear, and DECT's built-in encryption keeps team conversations private from outside listeners.
Each headset is constructed from lightweight, durable PC-ABS at roughly 168 g, with tactile volume buttons designed for blind operation and a 360°-rotating mic boom that auto-mutes when flipped up. Interchangeable on-ear and over-ear cushions let users customize comfort and hygiene for shared team use across multiple shifts.
The kit includes a total of 8 rechargeable batteries (2 per headset) plus a charger, so the full system can run continuously with hot-swappable power. The C1-4S can be expanded up to 8 headsets without a HUB, or scaled further with an optional HUB base for A/B grouping and an emergency ANNOUNCE function making it a flexible starting point for film productions, concerts, and public events that may grow their crew over time.
