Thanks for the anecdotal evidence, but in general those buds ended up in the trash in months, if not weeks. Out of all the people I know, pretty sure my wife is the only one that likes the wired buds that came with phones, but she went through a pair every few months. She switched to Pixel Buds a while back and only uses the wired ones when she runs, but still has to buy new ones twice a year.
IP67 in reality won’t last 30 minutes submerged in most cases. I’ve had flagship level IP67 devices get damaged by water ingress by being splashed or dunked a couple inches into a pool for less than a second. My Pixel 8 Pro goes into the shower, bath, pool, hot tub, and rain with me and it’s never skipped a beat.
