You've probably noticed that in the year 2009 the number of reviews of Bluetooth-headset on the site decreased markedly. If the 2008th to me fell into the hands of six or even ten different devices, but now that number is much smaller. Sometimes so much so that there is nothing new. The blame for this lies not with me, but the manufacturer, and can we call it a fault? The crisis forced to stop the boom Bluetooth-enabled devices, several second-tier manufacturers have simply disappeared from the market, key players reduced the range to a reasonable extent, peretryahnuli range. Order of abundance, it was before, will be gone. Such a large number of crazy ideas of mad money - too. So I now with great interest went up to writing any review of innovations among wireless devices, and especially to such as the Plantronics Discovery 975. It replaces the highly successful predecessor, Discovery 925. And the changes should include not only a different design, but also a number of other significant differences.
