As someone with high-end headphones and hearing aids that preclude earbuds, I will miss a headphone jack so much I'll probably get my first Android phone over this.
FWIW, there are MFI hearing aids with Bluetooth audio support (along with individual R/L volume control, profile selection and remote microphone support - seems pretty neat) that I've seen some people raving about on reddit. Rather expensive devices, but hearing aids in general are outrageously priced even for low-end models.
I have really good headphones but I just use the dongle. So I've never had an issue. Never lost the dongle cos I tied it to the end of the headphones with a small bit of velcro.
I thought I'd get used to it but after struggling with the dongle at first to use my preferred headphones (Cheapish Sony earbuds that I've found sound better than apple and last 2 years), then losing the dongle and resorting to earpods.
I now just carry two pairs of headphones everywhere, one for my Apple laptop and one for my Apple iPhone.
Even tried the Beats X, W1 chip was all hype it's barely any different from regular bluetooth and juggling with then UI to turn headphones on and off is more tedious than just plugging something in and living with a cable, so those are collecting dust now.
Didn't want to buy another dongle because that would just prove to Apple that people are happy with the dongle.
Obviously the shape of your ear matters a great deal, and the lack of wires makes the comparison a bit harder, but I've found the AirPods much more comfortable than the cheap wired headsets Apple ships (shipped?).
Beats. The only use they have are as a fashion accessory you hang around your neck. You don't play audio through them, not if you value your ears and your music.
