Five full-duplex headsets
Connect up to five wireless headsets with full-duplex team communication. Full duplex is what lets people interrupt and confirm the way they would face to face.
Per base station
Built & serviced in Lemoyne, PA — by firefighters, since 2009
Wireless base station
The DECT7 base for installed systems: five full-duplex headsets per base, with up to 100 listen-only users for tours and training.
One SON150 carries five wireless headsets in full duplex. Ten people who need to talk means two bases. Installed systems commonly run several, connected through a SON200-Series intercom or a SON104 analog intercom, so the count is a system decision rather than a per-base one.
The SON150 is the installed answer — mounted in a vehicle or a facility and wired to land mobile radios for an integrated system. If the system needs to travel to the work instead, the battery-powered ComHub is the same idea in a bag.

Product overview
The SON150 is what makes an installed Sonetics system wireless. It connects up to five wireless headsets with full-duplex team communication, and it runs on DECT7 — the same radio platform as the Apex 3-Series headsets, which is what keeps the audio crisp and understandable rather than merely present.
Installed is the operative word. Sonetics' own framing is that you install Sonetics in a vehicle or facility and easily connect wireless headsets with land mobile radios for an integrated communications solution. The base station is one piece of that: it sits alongside a SON200-Series digital intercom, which handles the radios and the auxiliary devices, or a SON104 analog intercom for smaller installs.
One capability is worth planning around. A single SON150 supports up to 100 listen-only users for tour or training applications. If your site runs plant tours, contractor inductions, or training groups, that is a genuinely different use case from a five-person work crew — one base can put a hundred people inside the same commentary.
The base is one layer of the system. See the APX379 and APX377 headsets for the crew side, SON200-Series digital intercoms for radio and auxiliary integration, and wireless ComHubs when the system has to move.
What the base does
The SON150 covers the installed work crew and the training group from the same hardware.
Connect up to five wireless headsets with full-duplex team communication. Full duplex is what lets people interrupt and confirm the way they would face to face.
Per base station
One base station supports up to 100 listen-only users for tour or training applications — plant tours, contractor inductions, or a training group following a single instructor.
Tours and training
The Sonetics DECT7 platform runs up to five channels, so multiple small work teams operate in the same area without ending up in each other's conversations.
Up to 5 channels
An APX379 or APX377 wireless headset pairs simultaneously with up to four Sonetics wireless base stations, so someone moving between zones stays connected instead of dropping out.
Up to 4 bases
Install in a vehicle or a facility and connect wireless headsets with land mobile radios for an integrated communications solution, through a SON200-Series or SON104 intercom.
Add access points and headsets as the team grows, connect multiple teams in the same work area, and stay connected moving between zones. The system is meant to be extended rather than replaced.

Before you request a quote
Divide the people who need to talk by five and round up, then add for coverage. A SON150 carries five full-duplex headsets; sites that cover ground add access points rather than trying to stretch one base. Send us a layout and the crew size and we will lay it out properly.
The SON150 is installed — mounted in a vehicle or a facility and wired into land mobile radios. A ComHub is battery-powered and travels in a bag to wherever the work is. Sites that have both a fixed operation and mobile crews usually buy both.
Yes, and it is one of the reasons to choose it. A single SON150 supports up to 100 listen-only users for tour or training applications, while the instructor positions stay full duplex. Tell us your group sizes and we will confirm the configuration.
Through a SON200-Series or SON104 intercom, yes — that is the installed integration path. 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. Send us your exact models and we will confirm the interface.
Yes. An APX379 or APX377 pairs simultaneously with up to four wireless base stations, so a worker moving across a site connects to the nearby base instead of losing the team.
