Indeed. Here in SE Asia, everybody still uses 3.5mm jack smartphones. It's a rare occurrence to see wireless earpods, and almost always these are cheap Chinese AirPod knockoffs.
This does not match my experience at all, but SE Asia is a diverse place.
Go to a random rural town in a midwestern US state and I'm sure you probably won't see people wearing Airpods, which is probably what people are picturing when someone says SE Asia.
We have paved roads believe it or not, as well as a large class of people who use the newest iPhones.
