Poly Sync 40 – Microsoft Teams Certified USB Bluetooth Speakerphone

Product Overview

The Poly Sync 40 Microsoft Teams speakerphone is the Teams-certified build of Poly's USB and Bluetooth huddle room speakerphone, carrying a dedicated Microsoft Teams button on the control surface for one-press access to the Teams client. Part number 77P35AA covers a huddle room or small conference room with a three-microphone steerable array and 89 dB SPL of output from a single 50 mm driver. It connects to a room PC or a user laptop over USB Type-A or USB Type-C and to mobile devices over Bluetooth 5.1, with up to 30 hours of talk time from the internal battery. For an IT team standardizing Microsoft Teams audio across flexible spaces, this is the SKU that matches the platform without adding a room system.

Product Description

Hardware certification for Microsoft Teams is what separates this SKU from the standard unified communications build. Certification means Microsoft has validated the device's audio performance and its integration with the Teams client, and the physical Teams button gives users a hardware path to raise the app, join a scheduled meeting, and see Teams notifications on the device rather than hunting through a laptop UI. In practice that removes the most common source of support calls in a flexible meeting space, which is a user who cannot work out which audio device the meeting is actually using.

Acoustically the unit is the same platform as the rest of the Sync 40 family. The three-microphone steerable array covers talkers up to 2.5 m (8 ft) away, with a 100 Hz to 7.8 kHz microphone bandwidth, echo cancellation, and noise reduction that keep HVAC and keyboard noise out of the transmitted signal. Full-duplex audio keeps both ends audible during overlapping speech. A bass reflex system with dual passive radiators gives the 50 mm driver a 75 Hz to 20 kHz range, which matters as much for content playback in a training session as it does for voice. An IP64 rating means the unit tolerates dust and splashes in a shared space where it will be handled by many people.

Two Sync 40 units pair wirelessly to each other to widen microphone coverage and increase output on a longer table, so a room can be extended without new cabling. Poly Lens handles firmware, configuration, and inventory across a deployed fleet. Where a room is large enough to need six microphones and twin speakers, specify the Poly Sync 60 for Teams Rooms; where a wireless connection to a computer is required rather than a cable, order the Poly Sync 40+ with the BT700 adapter. Personal and hotelling desks in the same Teams estate are covered by the Poly Sync 20, and users who need a headset instead of open audio can standardize on the Poly Voyager 5200 Office Teams headset.

Key Features

• Microsoft Teams Certified — Validated by Microsoft for Teams audio performance and client integration, so the device behaves predictably across a standardized Teams estate.
• Dedicated Teams Button — Raises the Teams client, joins scheduled meetings, and surfaces notifications from the device itself instead of the host laptop screen.
• Three-Microphone Steerable Array — Focuses on the active talker at up to 2.5 m (8 ft), covering a full huddle table from a single unit.
• 100 Hz to 7.8 kHz Microphone Bandwidth — Captures wideband speech so voices sound natural rather than telephone-narrow on the far end.
• Full-Duplex Audio — Keeps both ends of the call audible during overlapping speech instead of forcing participants to take turns.
• 50 mm Driver with Dual Passive Radiators — Produces 89 dB SPL across 75 Hz to 20 kHz for intelligible voice and usable content playback in a small room.
• USB-A and USB-C Cables Included — Connects to legacy room PCs and current USB-C laptops without buying a separate adapter.
• Bluetooth 5.1 with 30 m Range — Pairs with mobile devices for BYOD and hybrid use in the same room.
• Up to 30 Hours of Talk Time — A rechargeable lithium-ion battery recharges in under five hours, so a table with no power drop is not a blocker.
• IP64 Rated — Resists dust and splashes in shared and flexible spaces where the unit is moved and handled frequently.
• Wireless Pairing of Two Units — Two speakerphones link together for wider pickup and more output on a longer table.
• Poly Lens Device Management — Provides remote firmware updates, configuration, and inventory reporting across a deployed fleet.

Typical Applications

• Huddle room
• Conference room
• Commercial meeting space
• Multi-purpose room
• Training room

Technical Specifications

Frequently Asked Questions

What is the difference between 77P35AA and the standard Poly Sync 40 (772C4AA)?
Both use the same acoustic platform, the same three-microphone array, and the same battery. 77P35AA is the Microsoft Teams certified build with a dedicated Teams button on the device, and it is listed by HP under the Microsoft Teams unified communications platform. 772C4AA is the standard UC build and is Zoom certified. Choose the Teams SKU when Teams is the corporate standard and users benefit from a hardware Teams key.

Does the Teams button work without any additional software?
The button requires the Microsoft Teams desktop client on the connected host. When the unit is connected over USB to a PC or Mac running Teams, the button raises the client and joins meetings. Over a Bluetooth connection to a mobile device, standard call controls work but the Teams key behavior depends on the mobile client.

What size room does it cover?
Microphone pickup extends up to 2.5 m (8 ft), which fits a huddle room or a small conference room of roughly four to six seats. For a longer table, pair two units wirelessly. For a medium conference room, specify the Poly Sync 60 for Teams Rooms, which uses a six-microphone array and twin 50 mm speakers.

Is a Bluetooth dongle included?
No. This SKU ships with USB Type-A and USB Type-C cables for the wired connection and uses native Bluetooth for wireless pairing. If a wireless connection to a computer is required, order the Poly Sync 40+ (77P36AA), which includes the BT700 USB-A Bluetooth adapter.

How does it integrate with an existing AV system?
The unit presents to the host as a standard USB audio device, so it needs no DSP, amplifier, or matrix. In a BYOD huddle room it connects directly to a room PC, a display OPS module, or a user laptop. In a room that already has an installed video bar or codec with its own microphones, use the Sync 40 for BYOD mode rather than running it alongside the room system, so the space does not have two active microphone sources.

Can IT deploy and manage these at scale?
Yes. Poly Lens provides remote firmware updates, configuration policy, and inventory reporting, so a fleet across multiple sites can be held to one firmware baseline. Because the device requires no user training or in-room configuration, rollout is a distribution exercise rather than a commissioning exercise.

How is the unit powered and charged?
The internal rechargeable lithium-ion battery delivers up to 30 hours of talk time and recharges in under five hours. It charges over the USB connection, so a unit left connected to a room PC stays charged between meetings. Rooms without table power can run entirely on battery over Bluetooth.

What warranty and support apply?
The Sync 40 carries the Poly standard two-year limited warranty. Poly+ service agreements for extended coverage, advance hardware replacement, and technical support are sold separately; contact Creation Networks for the tier that suits your fleet size and deployment locations.
