I had a Motorola headset, and it felt heavy and hurt my ear.  I had complaints from my callers that they could hear static.  This BT500 is lightweight, fits perfectly, and the volume and on/off button are rubberized and very easy to find and use.  This isn't even in the same ballpark as my other headset. I could wear this one for hours.  I am petite, and it fit perfectly.  The unit came with several earpieces, so you can find the perfect fit.  I LOVE IT!
