> I'll argue that an device meant for phone calls (which is where bluetooth audio started out!) should aim for low latency by default. I also understand that the CPU/Latency/Memory trade offs made over a decade ago are not the same one's we'd make now.

It turns out that the device that's meant for phone calls has to, first and foremost, make sure that there are no dropouts, crackles and other buffer underrun articles. Latency comes afterwards.
