Who this is for

Production crews that need a compact, factory-paired comms solution will benefit from the Solidcom SE 4S Global. Use cases include commercial video shoots, location work near water, and other outdoor or noisy environments where ENC, wind and water resistance, and hands-free full-duplex talk are important.

Reliable communication and interference handling

The system supports full-duplex mode, allowing simultaneous two-way conversation to save time and improve coordination. It uses auto frequency hopping technology to switch to clearer frequencies when interference occurs. These features work together to keep conversations stable at the stated line-of-sight ranges.

Dual-mic ENC and sound clarity

The Solidcom SE Global uses dual-microphone Environmental Noise Cancellation to reduce background noise and present clearer voice audio. The system’s signal-to-noise ratio is specified at 71 dB, and the wireless frequency response is documented as 150 Hz to 7 kHz, helping maintain intelligible speech for team communication.

Design, comfort and battery workflow

The headsets use lighter materials and a replaceable over-ear earpad for comfort and hygiene. Hollyland notes the headset is super lightweight — approximately the same as an apple — and suitable for extended wear. Batteries are detachable and rechargeable, helping minimize downtime. The master headset supports up to 10 hours per charge, while the remote headsets can run up to 12 hours. A six-slot charging base and USB-A to USB-C cable are included for convenient charging; the headsets also support USB-C charging from optional power banks.

Durability in outdoor conditions

Hollyland built the headsets to resist water intrusion and reduce wind noise. Internal protective paint helps prevent water penetration, and the wind-reduction algorithm reduces wind-related audio disruption. These measures help keep the system operational in inclement weather and near waterside locations.

Easy setup and operation

The system ships pre-paired at the factory, which reduces setup time on location. Controls include a push-to-talk button, a movable microphone boom, and a latching design that toggles between mute and talk with a single press. These features aim to make the system straightforward to use during fast-paced shoots.

Expandability

The supplied configuration covers four users (1 master + 3 remotes). The system can be expanded by adding an additional remote headset to support up to five users on the same system, using the system’s transceiver limits.
