The Plantronics EncorePro takes a different approach to headset design. Every component has been designed and produced with one aim the best performance. The microphone is designed to sit in exactly the right place for optimum audio clarity, and the low slung design ensures it can not be seen by the wearer. The slim speaker has a wideband frequency response for clearer and more intelligible conversations. The EncorePro headset makes no compromise on reliability, durability, comfort or audio quality. EncorePro; Designed for performance - built to last.
