Not only that, unless you are using Airpods, iPhone bluetooth audio is far inferior to anything out there. Even cheapo Windows sounds better than iPhone bluetooth.

I've tested the stock dongle with high end and generic $1 dongles, and most, even audiophiles cannot tell the difference. Surprisingly the iPad Air 3 seems to have the best sound coming out of the audio jack, far outpacing any of the dongles and predecessors.
