Certainly worse than wired, but according to these tests AAC implementation on iPhone has an equivalent performance to LDAC 990. On Android and even MacOS, the AAC performance is much worse.Yes but AAC is so worse than wired or ldac….
I personally find AAC (from iPhone) sounding alright, cannot really pinpoint anything wrong or missing. However, when switching from BT to wired, the sound seems to get bigger, more detailed, but at the same time more pleasant, so tend to use wired more often.
