$40 dongle made in cooperation with Apple:
The Lightning Audio + Charge RockStar makes it possible to listen to Lightning Audio while charging your iPhone 7 and iPhone 7 Plus. Enjoy music or talk through Lightning Audio headphones while you charge. Use the RockStar anywhere; at home, at work, in the car or on the go.
Someone should make a long (3-4 feet?) USB-to-Lightning cable that has a short 3.5mm headphone jack Y-splitter at the end.
For people who charge while listening to headphones at their desk, Apple’s years-old Lightning dock has always had a headphone jack for audio out.
