William Gallagher, Apple Insider:

Yes, AirPods are clearly for playing music but you can rapidly choose where that audio comes from —and just what happens when you tap on the AirPods. AppleInsider details all the options.

This article goes beyond simply listing all the options you can assign to taps to each ear. For example, there’s this little nugget:

Just opening the AirPod case tells the iPhone to pay attention and shows battery information. You get the current charge of the case and an average of that for the two AirPods. Put one AirPod in your ear and now you get the individual battery charge for each one.

It’s worth checking this instead of relying on that average, too, because very often the two AirPods will have different levels of charge. Even though you always charge them in the case together, one may be significantly lower than the other.

That’s because one of them may have been acting as a microphone when you’ve received phone calls.

That last bit is pretty interesting and does explain why I sometimes have wildly different charge in my left and right AirPods.

Good post, worth a read.
