I researched this prior to buying this. I had purchased other ones, and had to take them back because I couldn't hear them, or people couldn't hear me because of ambient noise. Amazon had the best price, as well. 5 Stars for that- Amazon was about 1/3 less than the big box store. It was a great buy for me, and I recommend this to anyone who prefers clarity. Matter of fact, I purchased two of them. GREAT BUY!!!!!!
