The DuoPro has been designed from the ground up to withstand professional telephone applications. At the heart of the DuoPro is a convertible headset body, housing either the optional noise-canceling microphone or the featherlight voice-tube.
Configurable for every user, the Plantronics noise-canceling DuoPro is one of the most versatile headset ever made. The innovative Plantronics DuoPro offers all day comfort and best-in-class sound quality. The H171N is the convertible model with noise-canceling microphone. New ergonomic innovations offer unsurpassed comfort, and the patent-pending anti-twist boom ensures perfect microphone placement. NOTE: If you do not plan on buying an amplifier with this headset, and you would like to plug into your phone's 2.5mm jack, you'll also need to purchase an 18in. 2.5mm to Quick Disconnect adapter cord, which you can find on the accessories page.
