Attach your headphones to the dongle and leave it there. If you have more than one set, I'm sure Anker will make these for $4.99 a piece and you can buy a bunch.
Unfortunately only one of my devices has a lightening conveyor on it but I'd like to use those headphones for more than one device... Apple flubbed here no question about it, hopefully they bring back the jack with the iPhone 7s/8 . Meanwhile I guess I'll stick with my iPhone 6s
