Sometimes ago I found a pair of airpods on a pavement in my city. I started searching for the owner nearby, but nobody showed up, after I keept them in a drawer for a while hoping that the owner would enable lost mode, but they didn't. After 10 days without news I disabled location and started to use them. They are still thetered to the original account. I would be happy to return them, but the owner probably don't know or don't care..
