Sync 40+ speakerphone for flexible workspaces

The Poly Sync 40+ is a USB and Bluetooth smart speakerphone built for huddle rooms and flexible workspaces. It uses a multi-microphone array to focus on voices while reducing echo and background noise. Full-duplex audio allows natural conversation flow even when participants speak at the same time. The silver unit includes a rechargeable battery for cable-free placement.

Upgrade from basic laptop audio or single mic

This model replaces built-in laptop speakers and single microphones that pick up room noise and limit pickup range. The jump is worth it when meetings need clear voice capture for multiple people around a table. Two units can be wirelessly paired to cover larger meeting spaces without extra wiring. IT teams benefit from simple deployment and remote management via Poly Lens.

Check USB port availability and Bluetooth support

Verify your computer has a free USB port for the wired connection or supports Bluetooth for wireless use. Ensure your meeting platform recognises external audio devices for input and output. The battery provides up to 30 hours of talk time, so confirm charging routines fit your meeting schedule. No software installation is required for basic operation.

Questions about this item

What connectors does the Sync 40+ speakerphone use for power and data?

The unit connects to a host via USB for both power and audio, and it also supports a wireless link for pairing with a second Sync 40+ device.

What is the common mistake when pairing two Sync 40+ units together?

Users often try to pair the units over USB instead of using the wireless pairing mode; the two speakerphones must be linked wirelessly to expand the meeting space.

The battery provides up to 30 hours of talk time on a full charge.
