Did this upgrade at Oshkosh last year from the older Bose A20 bluetooth headset (only phone no music) to latest version and it works very well, one advantage is that the aural alerts from foreflight are now integrated with the headset which provides a somewhat more detailed traffic warning than the 796 aural alert.
It also means that when flying solo I do not need to have the intercom on to get music (I have an external music input to the intercom) although I know the latest intercoms have bluetooth built in these days.
With the iphone 6+ mounted on a magnetic mount on the panel I have a mobile info center for communications, texts, navigation and aural alerts etc. that works well as a backup to the systems built into the plane.
