Even a year ago there was no choice of bluetooth-headsets, only Ericcson actively produced them, but it was rather fashion product than commercial one. As a result, prices of accessories were very high; they were sold at half-price of the phone or even more expensive. Today the situation changes, a customer can choose a suitable wireless handsfree device among dozens of products and not only those ones that made by mobile phones manufacturers. The most important things today are convenience of bluetooth headset, its price and operating time. Let’s view advantages and disadvantages of several models. We won’t speak too much about technical features of each bluetooth headset, we’ll better share our impressions after using these devices. Frankly speaking, all devices, which are available on the market, are almost the same, the functionality depends more on the phone, which is used with this or that wireless handsfree.
