As I have said many times, the headset is akin to car speakers for mobile phones: The audience is like, like and phones is befitting, but still the product is not popular. Many Russian drivers use the speakerphone? I doubt it, which is the case even now such devices from the "telephone" the producer, but also embedded systems - well, when it is, maybe I'll even seize this opportunity, but so far just fetch the phone from his pocket and answer the call. Squeeze the old-fashioned phone arm, lit a cigarette, I will stand in traffic and communicate with a person, not being distracted from the road. I understand that it's wrong that you can not talk and drive a car, it's bad. Save sets, it is somehow more convenient than a separate unit on the visor, which must connect the phone to charge, to make of the car when he parked somewhere. Perhaps in Europe the cars do not compete, but we have a brilliant contraption attracts a criminal element with the crowbar.
