I have an iPhone 7. In reality even that isn't an issue. You can keep the dongle attached to your headphones and it will stick safely to it.
I would really like to know how many people who find issue with the dongle have day-to-day experience with a headphone jack-less device. My bigger concern is that headphone jacks will vanish from headphones.
Because I have broken all my headphones and then my phone's audio jack I am trying out the dongly life. So far it hasn't been that bad, but I suspect that there will be situations in which I'll want to charge and have an audio device connected.
I dislike Apples love for dongles, but the headphone donglegate is mainly a constructed problem by people that just want to rage about something. Sure, it sucks that you can't use your headphones while charging but in reality I had this problem exactly once in a year of usage. There are actual problems with modern smartphones and iPhones in particular but the headphone jack is a ridiculously propped up issue.
