I’m going to lose that dongle. You say further down that I can just leave them connected, but I use my headphones with more than my phone (laptop, desktop), and those other devices have a headphone jack. Leaving it plugged in to my phone sucks too, for obvious reasons.

I don’t care about water ingress. I’m happy to give up water resistance and have a slightly thicker phone if it means I get a headphone jack, bonus points if it’s easier to open the phone for repairs.
