I have an Apple Lightning headphone adaptor with my B&W P5 headphones connected to my iPhone 6S. The audio controls and microphone all work.

My first listening impressions suggest that there is a difference in sound quality between plugging the headphones into the iPhone's headphone jack and plugging the same headphones into the Lightning adaptor’s headphone jack, and that the Lightning adaptor's audio sounds “better".

Not a huge difference, but it sounds like while listening via the iPhone's headphone output the effect of compression is more noticeable than via the iPhone's Lightning output.

I'd be interested to see other reviews, especially a controlled "double blind" audiophile's test, but it looks like Apple's $10 adaptor can give the same improvement in audio quality as those $100 or more DAC headphone boxes
