Have been keeping an eye out for reviews for this, you seem to have been one of the first!! I'm surprised none of the main sites have done a review yet.
Quick question, have you had a chance to check out the mic quality?
Also, does the volume up / down actually work? Do you need to use the app for that, or does it do it out of the box?
They are pretty much double the price of the one+, but if there is a marked improvement overall in quality might considering buying a pair.
