I was concerned that this earpiece would not fit in my ear but it held down OK. I like the fact that I could swivel it and use it on my left or write. Sound quality is good, loud and clear. At times, I do hear static but I'm not sure if that is a Plantronics or my phone issue. It could be my phone. Sometimes, callers on the other end say that they can hear themselves talk but I think it maybe because I sometimes have the volume on maximum when I am outdoors. Once I lower the volume, that issue seems to be gone. This was my first blue-tooth and overall, I am satisfied with the price and quality and general ease of usage.
