The Plantronics SupraPlus Wideband (Noise-Canceling Monaural) headsets have enhanced audio and integrated call control. The adjustable headband, foam ear cushions and comfort T-Pad design make for a comfortable fit. The bendable click-stop microphone boom stays in position and can twist out of the way for picking up calls. The microphone's extended boom also improves noise-canceling and echo performance. The SupraPlus Wideband features Quick Disconnect, which allows you to walk away while still wearing your headset. Plantronics has optimized this headset for Microsoft Office Communicator.
