HP Poly Sync 40 Bluetooth USB Speakerphone – Bluetooth, USB-A/C, 6-Mic Array, UC Certified for Medium Conference Rooms (772C4AA)

The Poly Sync 40 UC (772C4AA) is a Bluetooth and USB-A/C speakerphone built for small-to-medium conference rooms and group workspaces of 4–8 people. Its 6-microphone array with Acoustic Fence technology delivers clear audio pickup across a standard conference table, dual passive radiators provide rich, full bass from a compact unit, and up to 20 hours of battery life covers full-day room use without recharging. Bluetooth and USB-A/C dual connectivity allows both wired PC and wireless mobile device connections simultaneously.

The Telecom Spot Take

The Sync 40 is the right speakerphone for conference rooms in the 10–15 person seating range where a personal-size device falls short but a full room video/audio system is cost-prohibitive. The dual passive radiator bass design means remote participants hear a noticeably warmer, more natural sound compared to typical flat-panel speakerphones at this price point. Acoustic Fence technology is particularly effective in rooms near noisy open-plan areas — it keeps near-room conversations from leaking into the conference audio. The Sync 40+ (772C5AA or 77P36AA) adds the BT700 USB dongle for better Bluetooth performance on older laptops.
