HP Poly Sync 40 USB/Bluetooth Speakerphone – 3-Mic Array & 30h Battery for Huddle Rooms (772C4AA)
Need clear audio for a small huddle space or flexible desk setup without locking it to one room? The HP Poly Sync 40 (772C4AA) gives our customers a portable smart speakerphone that plugs into a laptop or pairs with a phone and stays ready all day. Its three-microphone steerable array and 50 mm speaker keep voices natural in rooms up to about 5 m × 5 m. The 30-hour battery and IP64 rating make it easy to move between spaces.
The Telecom Spot Take
This is the speakerphone we point customers toward when they want reliable huddle-room audio without a permanent install. The 3-mic array focuses on the people in the room while the bass-reflex design with dual passive radiators adds clarity and some depth to voices. USB-A/C cable plus Bluetooth 5.1 covers both laptop and phone use. Poly Lens support helps IT keep track of devices. Best for small teams, shared workspaces, and anyone who needs to grab the unit and go. The two-year Poly warranty and Zoom certification add confidence for everyday business use.

Comparison at a Glance
Against other portable speakerphones in the same class:
- vs. Jabra Speak2 40 — Sync 40 adds Bluetooth and a long battery (Speak2 40 is primarily USB). Both offer IP64 and strong mics, but Sync 40 suits mixed laptop-and-phone use.
- vs. smaller personal speakerphones — The 50 mm driver and 2.5 m pickup cover a real huddle table better than single-mic personal units.
- vs. fixed room systems — You gain portability and 30-hour runtime; you trade the larger coverage of a dedicated bar or ceiling array.
