I can list quite a few improvements to AirPods:

* Wireless charging case

* More controls (perhaps touch sensitive long-press for Siri)

* Better switching between iOS/macOS (or generally - better support in macOS)

* Stereo mic support

* Native lavalier mic support in iOS camera

* Waterproofing

* One-device-multiple-airpods support

* Much much much lower price

* Thinner case

* Hearing aid feature (iOS 12 sort of does it via iPhone mic)

All that said, it's my favourite Apple product in past decade.

I love the fact that the AirPods don't have touch controls. I live in a place where some kind of headwear is required for over 6 months of the year.

I can just tap the side of my wool cap with thick-ass winter gloves and it works. If it was touch sensitive, I'd need to take off my gloves, pull the cap over my ear and fiddle with the earpiece. No thanks.

Not saying that should be taken away. If anything, it needs more gestures, perhaps triple tap for playing previous track?

I think these are fairly minor improvements, most of what makes the airpods great is already there. I’d rule out anything that makes them more complicated (that is their best feature imo) just putting in them and work is amazing, and it’s even better that they pause whatever’s playing when you take them out.

AirPod battery life isn't great when you're using the mic too (think a Skype call) but the fact that you can use one at a time while other charges makes it pretty manageable.

Good to know. My first thought for using a mic with a phone was for a "phone call" but I guess "skype call" works too ;)

I tend to make quick phone calls, but Skype/Zoom/etc on my computer calls tend to be of the 30 min - 2 hour variety, so that's where I see the most battery use :-)
