Air Pods-Apple Maps Voice Volume Too Low

Using Apple Maps app (the built-in app with iOS 10.2) and the Air Pods, the Siri voice volume giving directions is very low. It is so low that she really cannot be heard unless the environment is very quiet. This happens when no media, music or podcast is playing (either paused, or the app closed). If I play a podcast, or music from Music app, the Siri turn-by-turn voice is normal.

This condition is repeatable, and selecting Audio in Maps and adjusting Low, Normal or Loud does not help. I can hear the volume level changes, but all of these selections are too low to be useful, without some sort of media also playing.

In contrast, plugging in a 3.5mm pair of Ear Pods results in the Maps Siri directions volume to act normal without any media (music) playing. I had expected the wireless Air Pods to behave the same.

Additionally, this occurs whether my 1st Generation Watch (running 3.1.1) is connected or not (Watch powered off) so the Watch does not seem to be affecting it.

A) If there is a setting I am missing, please direct me there :-)

B) If this is not a setting, consider this as feedback to evaluate and fix in a future iOS.

Thanks,
