Overall, I've been extremely satisfied with Motorola's H7XX series.  I actually purchased the H710 and about the time the warranty was to expired I used it.  On Motorola's mistake, they sent me a H715 instead.  I didn't immediately notice though but little things were different.  The black shade was a little different and then I noticed "tones". Tones when I would connect, disconnect, etc. that I did not have with the H710.  I like both colors and they both go good with my original iPhone.  I think amazon has the best price on both of these... I would highly recommend them.  I am currently testing the Plantronics Voyager Pro and notice that it doesn't like my blackberry.  It works fine with my original iPhone but the voice quality isn't as great as it was with the H7XX series.  I'm returning it and requesting a replacement to see if it was just that one headset.  I'm really rooting for the PRO.  I find the H7XX series are easier to carry in the pocket as it folds nicely.  The PRO feels great and the smallest ear rubber piece works great for my ears.  I've had the headset on for hours and using the smallest ear rubber has worked the best. But enough of the Pro.  Thank you for your time.
