Title: Not up to expectations
Review: I purchased this unit because it was considered the "best" at blocking out background noises, such as in the car. After using it a half dozen times, I have concluded that technology has a long way to go. With the windows closed, the radio off, and in a quiet car, it still picks up much background noise and occasionally creates an echo on the other end of the line. It is better than any unit I tried in a store, but in my opinion not what it is hyped to be.
