Production Team Headset

The Hollyland Solidcom SE Pro 4S is a wireless intercom system built for film crews, event staff, livestream teams and houses of worship that need hands-free coordination. It supports up to four users simultaneously without a separate base station or bodypack. The 1.9GHz frequency band reduces interference from common Wi-Fi and Bluetooth devices. The bundle includes one master and three remote single-ear headsets plus a microfibre cloth, cleaning kit, stand and fastener straps.

Setup and Common Issues

The system arrives pre-paired so teams can start working immediately after charging. Each headset connects via a 3.5mm single-ear earpiece and uses a boom microphone with mute control for quick management. Dual-microphone Environmental Noise Cancellation helps maintain clear audio in loud environments. Dust and water resistance supports reliable use in changing conditions. The six-slot charging station and USB charging keep batteries ready with minimal downtime.

Pre-Order Checklist

Verify that the 1.9GHz band is permitted for wireless microphone use in your region before purchasing. Confirm that the 1300 feet line-of-sight range meets the distance requirements of your venue or outdoor site. Ensure all four users can operate with single-ear headsets and 3.5mm connections. The system is expandable, so check whether additional headsets may be needed for larger crews.

Questions about this item

How do I confirm the 1.9GHz link is stable after powering on the four headsets?

Each headset shows a solid connection indicator and you will hear clear full-duplex audio with no drop-outs up to 1300 feet line-of-sight; the master unit also displays signal strength for all three remotes.

Which items ship in the bundle and what must I purchase separately?

The box contains one master and three remote single-ear headsets, a six-slot charging station, rechargeable batteries, a microfiber cloth, 4 fl oz cleaning kit, a black headphone stand and touch-fastener straps; no extra accessories are required for basic operation.

Should I choose the 1.9GHz or 2.4GHz version for a crowded venue?

Select the 1.9GHz model because it operates on a band that avoids common Wi-Fi and Bluetooth interference, giving more reliable communication in dense RF environments.
