Up to 15 Apex headsets
Connect up to 15 Apex 3-Series wireless headsets for hands-free team communication up to 1,600 feet line-of-sight. One hub covers a crew most people would assume needs several.
Up to 1,600 ft
Built & serviced in Lemoyne, PA — by firefighters, since 2009
Portable systems
A battery-powered DECT7 base in a carry bag: up to 15 Apex headsets, five channels, 1,600 feet of range, and a two-way radio brought into the team.
SCH305 is the five-user hub and SCH310 the ten-user. SCH305-BT adds Bluetooth to the five-user hub, and SCH310T adds a tether port to the ten-user hub. The hub itself will carry up to 15 Apex 3-Series headsets, so the model names describe the packaged system rather than a hard radio limit.
Connect an optional portable two-way radio to talk to off-site crew or supervisors, and split push-to-talk lets a user transmit over a ComHub-connected radio or one direct-wired to the headset. Range is up to 1,600 feet line-of-sight, across up to five channels.
Displayed prices reproduce the supplied Sonetics 2022 price list, effective July 7, 2022, for the hub alone. EFES quotes the headsets, the case, and the radio adapters alongside it once the crew size and radios have been reviewed. Call (800) 504-2044.

Product overview
A ComHub is a Sonetics wireless base station that runs on its own battery and travels to the work. It ships in a high-visibility nylon carry bag with a shoulder strap and a detachable hanger hook, so it moves with the crew and hangs where the work is instead of sitting in a truck at the edge of the site.
Capacity is the number that surprises people: the ComHub connects up to 15 Apex 3-Series wireless headsets for hands-free team communication up to 1,600 feet line-of-sight. It runs up to five channels, so several small work teams operate in the same area without crossing conversations, and broadcast mode puts up to 100 Apex headsets in listen-only for training or tours.
Battery life is 24 hours on a four-hour charge, which is a full shift with a top-up that fits inside a lunch break. DECT digital encryption keeps the conversation private, which matters more on some sites than others but costs nothing to have.
The radio integration is the part that makes it a work system rather than a talk system. Connect an optional portable two-way radio to the ComHub and team members key it from their headsets, reaching off-site crew or supervisors. An APX379 or APX377 headset also pairs simultaneously with up to four SON150 wireless base stations, so a portable system and an installed one are not mutually exclusive.
Systems ship in Apex charging cases, are built from APX377 or APX379 headsets, and can include Apex Connect positions for people who are not in the noise.
What the hub does
The ComHub is a wireless base station that runs on its own battery and travels to the work. These are the capabilities that follow from that.
Connect up to 15 Apex 3-Series wireless headsets for hands-free team communication up to 1,600 feet line-of-sight. One hub covers a crew most people would assume needs several.
Up to 1,600 ft
Select from up to five channels for communicating with multiple small work teams, so crews working the same area are not sharing one conversation.
Up to 5 channels
Connect an optional portable two-way radio and let team members key the radio's PTT from their headsets, which is how the on-site crew reaches off-site crew or supervisors.
Operates up to 24 hours on a four-hour charge, so the hub is ready when you need it and a mid-shift top-up is realistic rather than theoretical.
Per charge
A high-visibility nylon bag with a shoulder strap makes carrying and moving the ComHub simple, and a detachable hanger hook lets you hang it high to maximise range.
Broadcast mode connects up to 100 Apex 3-Series headsets in listen-only for training or tours, and DECT digital encryption keeps private conversations private.
Up to 100 listeners

An APX379 or APX377 headset pairs simultaneously with up to four SON150 wireless base stations, so a portable system and an installed system work together rather than competing.

Before you request a quote
The hub connects up to 15 Apex 3-Series wireless headsets, up to 1,600 feet line-of-sight. Sonetics packages complete systems in three-, five-, and ten-user sizes with the headsets, hub, and charging case together, which is how most teams buy them.
The ComHub is battery-powered and travels in a bag to wherever the crew is working. The SON150 is installed in a vehicle or facility and wired to land mobile radios. If the work moves, buy the hub. If the work is where the equipment is, buy the installed system. Headsets pair with up to four base stations, so both can coexist.
Yes, through a two-way radio. Connect an optional portable radio to the ComHub and team members key its PTT from their headsets to reach off-site crew or supervisors. A headset can also be direct-wired to a portable radio with a Sonetics radio cable adapter.
Sonetics states compatibility with more than 400 radio models from manufacturers including Motorola, GE, Ericsson, Harris, ICOM, Kenwood, Maxon, Midland, Relm, Standard, Tait, and Vertex. We will not guess at your cable — send the exact make and model and we will confirm the adapter before anything ships.
Yes. Broadcast mode connects up to 100 Apex 3-Series wireless headsets in listen-only mode for training or tours, while the instructor stays full duplex with the working team.
