I previously owned the Motorola HX550. It was a superb product, with amazing range and very good clarity. However, I operate heavy equipment quite often, and although it wasn't too loud in the cab, it was sometimes hard to hear over the noise. The rubber pieces that went over the earpiece (too help it fit in your ear more snug) didn't last very long. My father has one and the rubber piece tore after a couple months. My rubber pieces only lasted two weeks. I dropped it in water and thus I had to get a new earpiece, the Samsung HM1700.

This earpiece (The Samsung HM1700) fits my ear without a rubber piece much better, but people have trouble hearing me on it. Not only that but it doesn't have much of a range. You get 10 feet from it and it disconnects. The Motorola HX550 you could walk 40 feet away from, and you would still be connected to it. I don't like the position of the volume up/down buttons. They are on the bottom, and the hang up button is on the top. When you squeeze the earpiece to adjust the volume, you sometimes inadvertently end the call. This piece makes a good backup in case your main earpiece goes down, but poor button placement, lack of noise reduction, and a poor microphone, keeps this from being anything close to an elite earpiece.
