Hollyland Solidcom SE-4S Wireless 4-Person Noise Cancelling Headset Intercom - Double Ear Version

Precision Coordination Without the Noise

The Hollyland Solidcom SE-4S is a professional full-duplex intercom system built for small-to-medium teams. This 4-person setup—one master and three remotes—replaces "push-to-talk" with natural, simultaneous conversation. From film sets to live festivals and waterside operations, it ensures every directive is delivered with absolute clarity.

Dual-Mic ENC: Silence the Chaos
The Solidcom SE-4S uses advanced Dual-Mic Environmental Noise Cancellation (ENC) to cancel up to 20dB of ambient noise. With a 71dB Signal-to-Noise Ratio, your voice remains the priority even amidst cheering crowds or heavy wind, ensuring faithful audio reproduction that reduces team fatigue during long production days.

Unfailing Connectivity and Range
Operating on a stable 2.4 GHz band, this system delivers a reliable 350m (1,100ft) line-of-sight range. Auto Frequency Hopping technology instantly switches to clean channels if interference is detected, providing a rock-solid link so you can focus on the event without worrying about dropped connections.

Rugged Ergonomics for the Professional Workflow
Weighing just 185.2g—roughly the same as a smartphone—each headset is designed for all-day comfort. Units arrive factory pre-paired for instant deployment and feature an IPX4 water-resistant design with internal protective paint, shielding sensitive electronics from sweat, moisture, and light rain on unpredictable outdoor shoots.
