Plantronics conducted the largest ever human-factors study of the ear before designing the Encore headset range. This study, of over 700 ears, resulted in a headset created for supreme comfort and stability. Encore's unique Sound Enhancement System allows users to alter the tone of their caller's voice at the flick of a switch. It's quick and easy to change a normal telephone tone into a fuller, richer sound. Encore Monaural headsets, which provide sound in one ear, are ideal for users who may need to confer with colleagues when making or taking a call. As with all Plantronics office headsets, the Encore features Plantronics patented Sound Guard Plus and Call Clarity technology. Its easy to use Quick Disconnect feature places the caller on hold, while allowing users to leave their desk without removing their headset. In addition, this noise-cancelling Encore model is ideal for use in situations where background noise can interfere with clear communications.
