This little device fits comfortabe and sturdy on your ear. It has both earloop and earbud. It also comes with two different shaped "fitters" that's places over the earbud (so you can pick which one works best with you). When I use my bluetooth, I hear the person loud and clear. I have had complaints that sometimes they don't hear me too well. That usually happens when I'm inside the mall, or stores, but sometimes they do. Maybe it's the location? I'm not sure. However, usually it works fine. I just love the pretty color and the look is very simple, not too flashy.
