My car already transmits sound through the lighting port, doesn't sound any different than when plugged into the aux cord, i don't see the need for this.
I'm going to wait and see how it plays out.
But if they make crazy priced adapters or no wireless charging.
I will get a 6s (which more than likely will get discounted) or go to Samsung.
The Galaxy s7 Edge is so gorgeous so its tempting....
