I'm usually pretty good keeping track of my AirPods. I have two pairs. One for the car and one that I use at home. The other day I noticed I didn't see the pods in the car. Sometimes they will end up in the house if I'm on a call when I get home. I tried the find my iPhone app which isn't helping because I have a home and car AirPod in the same case. No luck getting the other of the pair to beep so I'm starting to doubt they are in the house (not in the car either). I lost another pair while at the Apple Store a year ago. I think it slid out of my pocket while my kids and I were taking a coding class. Hopefully the current lost pair will be found when I do some through New Years cleaning.
