This is a pretty good product, if you are not in a noisy environment such as a car with the window open or a jeep with the top down. I was walking a very, very strong wind and the person I was talking with said they could hear my voice loud and clear...without hearing the wind. The problem was that I couldn't hear them. The device never really fit in my ear very well. It sort of just sits in your ear. It doesn't seal or fit snugly at all. So I couldn't hear them. And with any external noise at all, I could not hear the person. It was frustrating. I really wish that it had a different type of ear fitting, because I loved how well it blocked the wind. I wouldn't recommend this for use in any vehicle or noisy location, but would recommend it for other purposes.
