I've gone through just about all the different headsets, and I've finally found the H710 the best!  I nicknamed it the 'beetle' since it reminds me of a beetle when you fold it up.  What I like about it: I can wear it for hours and never get a sore ear or worry about it falling off. The Jawbone, BlueAnt and Plantronics Voyager 510 hurt my ear. Plus, each of those units had different issues that either didn't connect properly, stay connected, or were difficult to utilize.
