Poly Sync 40 USB/Bluetooth Smart Speakerphone Standard
The Poly Sync 40 is a USB and Bluetooth smart speakerphone sized for huddle rooms and flexible workspaces up to about 5 m x 5 m. A three-microphone steerable array follows whoever is talking as they move around the table and picks up voices out to 8 feet, while noise and echo reduction keep the far end on the conversation rather than the ventilation. Full duplex audio lets two people talk over each other and still land. A single 50 mm driver in a bass reflex enclosure with dual passive radiators carries the low end, so voices sound like voices instead of like a laptop.
It reaches a PC or Mac through the integrated combined USB-A and USB-C cable and a phone over Bluetooth 5.1, so there is no dongle to lose. The 5000 mAh lithium-ion battery runs up to 30 hours, which means the unit does not have to live next to an outlet, and a USB-A port on the side will top up a phone. Two Sync 40 units can be linked wirelessly to cover a longer table. Touch controls handle call, mute, and volume, two light bars show call status from any seat, and the IP64 housing shrugs off dust and spills. This is the standard version, Poly part number 216874-01, for Zoom and a wide range of other platforms.
