The DA40 USB Headset Adapter by Plantronics converts any H-Series headset, including the latest wideband models to USB. Plantronics H-series headsets are equipped with a proprietary, 4-pin QD (Quick Disconnect) connector traditionally designed for desk phone operation. The DA40 now makes it possible to use these QD equipped headsets with almost any computer and VOIP (Voice over IP) applications. This helps contact centers and other businesses leverage their existing investments saving both time and money.
Plug-and-play USB connectivity for fast, simple setup
