Hollyland Solidcom SE Pro 9S 9-Person Full-Duplex Single-Ear Headset Intercom System

The Hollyland Solidcom SE Pro 9S 9-Person Full-Duplex Single-Ear Headset Intercom System provides small- to medium-sized production teams with a cost-effective yet competent communication solution. This configuration includes one master single-ear headset and eight remote single-ear headsets, operating across the 1.9 GHz frequency range. Lightweight and robust, the system features dual-mic Environmental Noise Cancellation, dust and water resistance, and long battery life, allowing teams to collaborate effectively across a wide variety of environments—from commercial video production to waterside operations. The system can be expanded with additional remote headsets to support up to 9 users.

The SE Pro 9S supports full-duplex communication, allowing team members to speak simultaneously without taking turns. This saves valuable time and enhances workflow efficiency. With a line-of-sight operating range of up to 400 metres, the system avoids interference with Wi-Fi and Bluetooth-enabled devices. Automatic frequency-hopping technology ensures the system remains stable and reliable by switching to a precise frequency whenever interference is detected.

Featuring advanced dual-microphone Environmental Noise Cancellation, the SE Pro 9S cancels out background noise so that your voice comes through clearly even in noisy surroundings. With a signal-to-noise ratio of 71 dB, the system delivers intelligible speech, helping teams communicate effectively in challenging conditions.

The headsets are rugged and designed to withstand dust and water exposure. Internal protective coatings safeguard the components from moisture and sweat, ensuring the system remains operational even in wet or harsh conditions.

The system is ready to use straight out of the box, as all headsets are pre-paired at the factory. The movable microphone boom allows intuitive control of mute and talk functions, while the included 3.5mm monitoring port supports integration into wired setups.

Battery life is generous, with 18 rechargeable batteries included. Remote headsets provide up to 10 hours of operation with noise cancellation enabled, while the master headset lasts up to 5 hours when connected to 5 remote headsets. Batteries can be fully recharged in just 3 hours using the supplied USB cable or the 8-slot charging station, ensuring minimal downtime for continuous production.
