I really like this headset and I have many!  This headset was very easy to sync and works well with the Apple iPhone.  The volume buttons are very easily accessible and the charge last for a lengthy amount of time  I love how I don't have to worry about having something stuck in my ear!  I hate those types of headsets.  This fits at your ear very comfortably.  I would have liked the volume feature to be a little louder, as I have found myself not able to hear as well as I have on some of the "in the ear" bluetooth sets.  The only other thing that I don't like is that the access the charge is not universal.  It has a different prong type, so I can't use the generic USB cables that I have used for several of my other headsets.  And, now I have misplaced the cord, so I haven't been able to charge it.
