Is it me or does the 6 Plus have better audio output...

With headphones?? Seem louder to me.

So louder = better? Probably just a placebo effect as I haven't seen anything talking about the audio quality. That said, could also be one of the undocumented changes.

Yes louder as in better. The output of previous iPhones hasn't been that great.
