The lowest level of the three is not a useful number. The case serves as a battery pack to recharge the headphones (something I did earlier today while on an international flight).

The reality is the sort of compatibility being talked about is a new feature with design choices, not just unwired functionality.

I'd rather them work on features to report charging time or expected playback time on iOS, or write their own app for Android, than try to arbitrarily increase their bluetooth profile compatibility checklist.
