Hollyland Solidcom C1-2S Full-Duplex Wireless DECT Intercom System with 2 Headsets (1.9 GHz) (1 Master+1 Remote)

The Hollyland Solidcom C1-2S is a true-wireless, full-duplex wireless intercom system designed for two-person crews—such as a single director and camera operator, a pair of stage technicians, or a two-person wedding videography team.

Operating on the license-free 1.9 GHz DECT 6.0 spectrum, this setup relies on a completely hubless architecture. Instead of requiring a bulky desktop base station, the system anchors its wireless connection entirely around a single Master headset. It provides a fluid, simultaneous talk-and-listen environment across an expansive operational radius, letting both operators communicate completely hands-free.

Core Hardware & Operational Strengths

• Hubless Architecture for Rapid Deployment: By tossing out a traditional desktop base station, the entire system is highly portable and can deploy in under a minute. One headset features a distinct red nameplate and serves as the Master router. The second remote unit features a blue nameplate and syncs directly to it automatically upon powering up.

• True Full-Duplex Dialogue: Functions exactly like an open phone call. Both users can speak and hear each other simultaneously without pushing buttons, completely avoiding the choppy, one-way constraints of traditional push-to-talk (PTT) walkie-talkies.

• Muscle-Memory Smart Muting: Toggling your live microphone is completely intuitive. Swiveling the microphone boom arm straight up past 30 degrees produces a physical click that instantly mutes your voice. Bringing the boom arm back down past your jawline opens the channel back up instantly.

• Acoustic Vocal Tuning: The internal drivers are custom-tailored with a 150 Hz to 7 kHz frequency response optimized specifically for vocal intelligibility. This acoustic profile aggressively filters out low-end camera rumble and high-end hiss, keeping dialogue crisp even on busy show floors.

Power Architecture & Battery Lifecycle

Because the Master headset (red nameplate) serves as the primary processing anchor and handles data routing for the remote unit, its power draw is substantially higher:

💡 Future Team Scaling Potential: Buying this 2-headset kit does not lock you into a small setup forever. Because the Master headset included in this package features the exact same hubless firmware architecture as larger bundles, it can scale up to accommodate up to 7 remote headsets simultaneously (an 8-person maximum crew ceiling). If your production team grows down the line, you can simply purchase standalone Solidcom C1 remote units, pair them directly to your existing Master headset using a USB cable, and expand your communication network seamlessly.
