The JX10 exceeded my expectations for size and weight. Honestly I keep forgetting whether or not I'm wearing it. But...The earhook snapped in two as soon as I put it over my ear. It's back together now with a piece of tape, and Jabra is sending free replacements. But I would never keep the JX10 tucked in my pocket for fear of more damage. I guess I have to wear it all the time, huh?Not many headsets yet have digital signal processing, which was a must-have item. The JX10's sound clarity is good in both directions, but there is a noticeable difference even between two feet and four feet from the phone. Beyond three feet, it starts to crackle. Forget about 30 feet.In retrospect I should have chosen one of the headsets that come with several interchangeable ear gels. This one has none, and it's too big to go fully in my ear, so I have to use the earhook and turn the volume all the way up.The buttons are too hard to press. Admittedly I have large fingers, but these buttons are very tiny and don't stick out far enough to press them easily.It's not a strike against the JX10, but apparently I cannot use it for voice-activated dialing with my current phone (LG VX5300). This may or may not work on your phone. I can still pick up the phone and dial normally, and the JX10 automatically picks up the signal. And I can also do last-number-redial without touching the phone.I would be willing to sacrifice a bit of smallness and lightness for something else with ear gels, a stronger earhook, raised buttons, and range even half as good as Jabra advertised.
