Poly MDA220 USB-A Headset Adapter

The Poly MDA220 USB-A Headset Adapter connects compatible Poly headsets to a computer through a standard USB-A port. It supports the Blackwire, Voyager, Savi and EncorePro USB families for unified communications. The adapter is a new accessory listed by the manufacturer in 2024.

USB-A connectivity for Poly headsets

The single specification that determines fit is the USB-A interface, which must match an available port on the host device. This adapter enables plug-and-play audio for the supported Poly headset families without requiring additional drivers. No other interface or connection type is provided by this model.

Suits users with USB-A ports and compatible Poly

Buyers who need a Bluetooth link should look at the separate BT600 adapter instead. Users whose headsets require a different connector or who lack a free USB-A port will not be able to use this unit. It is designed specifically for the listed Poly series and does not support other brands.
