Sound Quality for the Leaders

Encore is the first lightweight communications headset with SES (Sound Enhancement System) tone control switch. Encore also supports the benefits of Sound Guard Plus and Call Clarity technologies: speech that is comfortable to listen to and easy to understand, plus voice transmission quality that exceeds that of many headsets.

Comfortable and Convenient

Plantronics has conducted the largest human-factors study of the ear ever undertaken to design this super-stable, super-light headset. With multiple adjustments possible, the Encore headset will fit just about anyone comfortably. The headband and turret are click-stop positionable to maintain the right fit. Binaural models and designed without a cable yoke.


The Encore headset is the most rugged Plantronics has ever designed. Even the new lighter weight cables are strong. A durable turret, rugged cable strain relief, and rigid ISO 9001 quality testing, result in a headset that can take day-in and day-out use.
