I bought this for my husband so he could use it at work. We had tried Motorola and Jabra earpieces. With both of them they were so noisy to the other person between movement and background noise. I discouraged him to use it. So when he wanted this one I said oh no here we go again. Amazingly when he uses the plantronics ear piece I cannot even tell that he has the earpiece on. I think it is great! The noise cancelling really works.
