I LOVE this design. I can just flip the boom and I don't have to worry about my headset calling anyone.  The previous bluetooths I owned called people from my purse, which I hated.  With the H710 not only does is not call people accidentally but it also saves the battery.  I could go a few days without charging it which, is great in my opinion.  As soon as I open the boom the phone recognizes it and I could use it again.  There were a few times I had to manually sync the bluetooth but that is a minor set back.
