Well, it works alright if you are inside and the phone is right in front of you. It does not get the claimed 30 ft range, not by a long shot, I'd say it gives you about 10 maybe 12 feet. The noise reduction sucks. It does not block wind or people talking in the back ground. I can't say how it works in the car because I do not own a car and I do not drive. I can say that it does not work while riding your bike, even if you are riding slow. If you happen to live in a windy area and want to use it outside, forget it. It works alright in quiet areas and that is about it. I guess thats what you get at this price.
