We tested the Plantronics Voyager Pro Plus with the Apple iPhone 3G and were amazed at the call quality. The audio quality was crisp and clear, with hardly a trace of static or wind noise. We tested it in a busy outdoor cafe and our listeners thought we were indoors. Indeed, it appears that Plantronics' Audio IQ 3 and Wind Shield technology really works as advertised. Callers also said our voice sounded quite natural, with only the occasional echo or hiss.
Other features of the Voyager Pro Plus include multipoint, call-waiting support, last number redial, and call mute. It has a rated talk time of 6 hours and a rated standby time of five days.
