Designed for use in customer service centers, the HW530D Encore Pro 500 Over-the-Ear Monaural Headset from Plantronics features the DA90 USB audio processor and Plantronics Manager Pro software to give administrators the ability to track a variety of details about each device. Plantronics Manager Pro software (sold separately) also gives IT the ability to monitor and manage an entire fleet of headsets to ensure all headsets are functioning properly. Once configured, the headset offers improved comfort with a flexible boom and a soft, breathable ear cushion that allows it to be worn for extended periods of time.
