Product Description
The Poly Sync 40 Audio Conference Phone is a professional USB and Bluetooth conference speakerphone designed for small meeting rooms, huddle spaces, home offices, and business collaboration. It combines a high-performance speaker with a three-microphone steerable array to capture voices clearly while helping reduce unwanted background noise. The device supports both wired and wireless connectivity, allowing it to connect to a computer through USB Type-A/USB-C or to mobile devices through Bluetooth 5.1.
The Poly Sync 40 features a 50mm high-performance speaker with a 75Hz–20kHz speaker bandwidth. Its full-duplex audio, noise and echo reduction, and bass-reflex design with dual passive radiators are designed to provide natural voice reproduction and clear conversations. The microphone system provides up to 2.5 metres of pickup range, making it suitable for small meeting rooms.
The conference phone includes a rechargeable 5000mAh Li-ion battery providing up to 30 hours of talk time. Users can pair up to eight Bluetooth devices, while wireless daisy chaining allows compatible Sync devices to be connected for larger meeting environments. The unit also includes highly visible status indicators and convenient touch controls for calls, mute, volume, Bluetooth pairing, and programmable functions.
With its compact design, approximately 610g weight, and IP64 protection, the Poly Sync 40 is suitable for professional conferencing, online meetings, hybrid collaboration, and business communication.
