Been using this on the iP6 for the past week, had about 18 hours of voice calls this week.
First off, when it works, it is a VERY crystal clear call. As in you can literally hear someone wet their lips. Call quality is what you'd expect from a high-grade VOIP call via headsets during gaming or skype calls. Very pleased with the quality.
Downsides are:
-My current generation Voyager Legend UC doesn't seem to support the HD voice quality. Not sure that any BT headset supports it yet to be honest. When you switch to headset from using the phone, your voice quality to the listener and theirs to you reverts back to a slightly-upgraded (subjective opinion) level of fidelity from normal voice calls. But if you move from the headset back over to speaker phone or just using the phones built-in audio...wow, really crisp again.
-If you are mobile and move in/out of LTE service areas (or even into a weak LTE service area), the call just drops. No handoff, no temporary downgrade of voice quality, it just flat out drops. Annoying and hopefully something that will be addressed via handoff software at some point in the future. Doesn't happen if you are stationary, and doesn't happen all that often in general unless you've got a spotty service area, which I do when travelling through mountains, tunnels, or wherever signal moves around.
Simultaneous data works during the calls as well, obviously.
