Featuring a unique Sound Enhancement System (SES), Encore headset users have the option, at the flick of a switch on the headset, to listen to the caller's normal telephone voice or to adjust the sound for a fuller, richer tone. Encore headsets provide a perfect acoustical fit, adjustable headband, and soft ear cushions for optimum comfort, stability, and fit.

Encore Monaural headsets, with sound in one ear, are lightweight and are ideal for users who may need to confer with colleagues when making or taking a call.

The Encore Monaural Noise-Cancelling models have all the features of the standard Encore headsets, but use a unidirectional, noise-cancelling microphone mounted on a flexible stem in place of the trademark clear and curved Plantronics voice tube. By eliminating up to 75% of all background noise, the noise-cancelling headsets make speech much clearer in noisy environments.
