I won't buy a phone that doesn't have it. I hate to charge my wireless earbuds, also they break after a few years for no reason because the battery got old. So I have a physical aux headset, will last me 10 years easy and never needs charging.
BUT the other day someone suggested to just get an usb-c to aux adapter and I'll probably do that in future if the aux connector isn't present on the next phone.
I've had the exact opposite experience. I have a literal pile of dead wired headsets (most were mid quality but two of them were >100$) but not a single one of the 4 wireless headsets ive had since then have died (the first one i bought have admittedly had its battery degraded to where it can only live for an hour or two, but its nearing on 10 years old now).
Not saying you can't have the opposite experience, but from my point of view last noticably longer at a similar priceclass (and i run them pretty hard both physically and time wise, easily 6-10h/day, with workouts most day). I've been running my jabra elite 65t for over 5 years now as my only headset which is the longest i've ever had a single headset. Though admittedly i lost my case 1.5 years ago while biking but i managed to find a secondhand case.
