I’m looking forward to getting this in a few days for phone and AW4. Sadly,the Beats Pro wireless buds need a lightning cable or this would be perfect for me.I don't like the idea of bilateral charging. Mainly because I don't want to sacrifice precious phone power for another device. If Apple doesn't the functionality, I hope that they haven't included the hardware for it (assuming that the hardware is different from one way Qi charging).
