Portable speakerphone with Bluetooth and USB-A

The HP 772C8AA Poly Sync 20 is a compact speakerphone designed for professionals who need clear audio on calls and music playback while moving between locations. It connects to smartphones wirelessly via Bluetooth and to computers through a USB-A cable. The device carries Microsoft Teams certification with a dedicated button for instant app access. Its IP64 rating provides dust and water resistance for travel durability.

Connects to phones and PCs while charging mobile

The speakerphone links to a PC or Mac using the included USB-A cable and pairs with a smartphone over Bluetooth for simultaneous device management. A built-in power bank function keeps a connected phone charged during long sessions. The multi-microphone steerable array reduces echo and background noise, while full-duplex audio lets participants speak at once without clipping. Up to 20 hours of battery life supports extended use away from wall power.

Suits mobile workers needing one device for calls

This unit fits users who want a single portable tool for conference calls, music and phone charging on the go. The carrying case and lanyard aid transport between home, office and travel settings. Buyers who require a stationary desktop speaker with higher output power or additional connectivity ports such as USB-C should look at alternative products. Those needing a larger multi-room audio system will not find that capability here.
