Honestly, I do not like car headset, in my opinion, this is absolutely a waste of money. See for yourself: you pay your hard-earned money, and the output is questionable usefulness of a device that will help you communicate without using their hands in the car. However, regarding the "no hands" is a strong word, because one way or another have a mobile phone to dial a number (for voice dialing is not always working perfectly), respond to messages and so on. Moreover, the use of a headset imply the cigarette lighter, I watched dozens of motorists who initially dragged these things home to recharge from the mains, but then just left them in the glove compartment and charge the car from time to time. I'm leading up to the fact that many in fact use and navigators, so take a cigarette lighter does not want a Chinese "razdvoiteli" personally I do not cause the desire to use them, feel sorry for expensive equipment. In short, these toys will never be compared with integrated vehicle manufacturer system, if any, well, with some "serious" accessories designed for the implementation of the speakerphone. Headset on his ear for a thousand rubles, and it gives much greater opportunities, although manufacturers recommend using a car and hands-free in the office, at home and so on, this idea does not seem to me attractive, too painful to becoming a public dialogue.
