Hollyland Solidcom SE Global Version Wireless Intercom

The Hollyland Solidcom SE Global Version is a full-duplex wireless intercom on the 2.4 GHz band, with single-ear headsets that let everyone talk and listen at the same time.

How It Works

Each kit has one master headset, marked by a brown headband, and one to four remote headsets with black headbands. The remotes come paired to the master from the factory, so the system is ready as soon as the headsets are switched on, and pairing is needed only when a headset is added.

The line-of-sight range reaches up to 1,100 feet (350 m), and automatic frequency hopping moves the link away from interference.

Noise Reduction and Audio

Each headset uses two microphones for ENC, which cuts the noise around the speaker by more than 20 dB, so the team hears voices rather than the room. Audio covers 150 Hz to 7 kHz.

Headset Controls and Power

A single press of the TALK/MUTE button switches between talking and muted, and a long press turns on push-to-talk. Moving the mic boom up or down mutes or opens the mic as well.

The removable 770 mAh battery charges in under 3 hours in the 6-slot charging base or over the headset’s USB-C port, and a headset can charge while in use. The master headset runs about 10 hours with four remotes connected. Each headset weighs about 185 g with its battery, and its ear pads and mic cushion are replaceable.

An internal coating protects the headsets from sweat and moisture, though they are not fully waterproof. With a Hollyland USB-C to 3.5 mm adapter, sold separately, a 3.5 mm earpiece can be used with the headset worn around the neck.

Choosing a Kit

The 2S kit holds a master and one remote headset, the 4S a master and three remotes, and the 5S a master and four remotes. Every kit comes with one battery for each headset and a 6-slot charging base. The Configurations tab compares the three kits.
