The aux cord in the car was actually a major concern for me too when I was considering upgrading to the 7. And then I found this $15 bluetooth FM transmitter: https://www.amazon.com/gp/product/B01KJJP1TG/ https://www.amazon.com/gp/product/B01KJJP1TG/ The sound quality is fantastic and it's easily way more convenient than using an aux cable: No cord, and it has play/pause and track skip buttons on it! Also has a microphone for Siri/phone calls though I've never used it to speak to its quality. There are a bunch of similar ones on Amazon with slightly varying features. I do understand it would be frustrating to swap the dongle around if you have multiple headphones though. Worth noting that the "crappy included ones" that come with the phone are already lightning though so they don't need an adapter.
