Plantronics’ Voyager PRO, designed for business pros who wear the headset more than six hours a day, effectively combines advanced audio technology with a smart, precise design that screams performance and reliability. Voyager PRO endured an extraordinary 24 rounds of human factors testing to perfect the design for all-day wearing comfort and stability. The behind-the-ear wearing style is perfectly counterbalanced, so weight is distributed evenly, rendering it virtually weightless when worn. The ear tip is made of soft silicone for an optimal fit and features an intuitive user interface with easily accessible power, volume and mute buttons, as well as voice prompts.
