Poly Speakerphone SYNC 20+ M USB-A / BT600

Easy connectivity: Connect smartphones via Bluetooth or connect wirelessly to computers via the included BT600 adapter, which comes paired to the Poly Sync 20+. This enables better audio performance than connecting directly to PC/Mac via Bluetooth.  Hear and be heard: Keep the focus on your voice, not the background noise with a multi-microphone steerable array for echo and noise reduction.

It’s slim and portable, IP64 dust- and water-resistant, and comes with its own carrying case.  All in one: Portable speakerphone + portable charger + high-performance music speaker. Enjoy more clarity on every call thanks to the bass reflex system with dual passive radiators for natural voice and deep bass.  Microsoft Teams version: Supports easy collaboration and communication with a dedicated Teams button for instant access to the Teams App.
