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.

Obviously that is objectionable on a $$$ apple tax $$$ level, but pragmatically it's not much of an issue.

I do still miss the mini RCA jack, however, because on occasion I do forget my headphones & adapter and can't use any other normal headphones. (And I hate charging headphones and wearing batteries on my ears)
