March 31, 2006 – In 1969, when Neil Armstrong's headset carried the historic first words from the moon: “That’s one small step for man, one giant leap for mankind,” it was almost to predict that just a third of a century later, a significant proportion of the population would be wearing wireless headsets on a semi-permanenet basis. Once worn for mission-critical applications such as air traffic control, 911 dispatch, and and fighter pilots, the technology available in a Bluetooth headset for the mobile phone now considerably outstrips the most sophisticated headsets available regardless of cost just a decade ago, and continues to evolve rapidly. Plantronics will debut two new headsets next week at CTIA which push those boundaries. The US$150 Discovery 645 and US$80 Voyager 510 with WindSmart, both incorporate new technologies for audio clarity during conversations. The Voyager 510 is the first Bluetooth headset on the market to include both a noise-canceling microphone and wind-reduction technology for brilliant sound in windy environments. The Discovery 645 includes a digital signal processing (DSP) chip to actively reduce background noise when talking.
