I bought this phone through Amazon and I am extremely unhappy with this piece.I have to stay inside noise proof rooms to speak to someone clearly. The moment I step out even in a quiet road, the opponent cannot hear me clearly. There is a heavy disturbance with a hizzing sound. Even a slight breeze creates enourmous disturbance.This problem aggravates in a place like Boston Downtown if you are taking a call on the street.The connection with headset got dropped couple of times for no reason, and I had to restart bluetooth sservices to speak again. Overall I am not happy with the product and planning to return it to Amazon back.
