I had a Motorala BT set before but it wouldn't stay on my ear and I could barely hear the person talking to me.  This Plantronics, however, stays on my ear nicely and the volume controls are easy to use and on the right spot. I can talk hours on a single charge, and it doesn't drain the day lights out of my phone. I drive a manual transmission car and having this set really makes my daily drive productive and much safer.
