I see ads on Facebook Marketplace and the like for used AirPods and it grosses me out. I can’t imagine putting that in my ear after it was in some stranger’s ear. I feel similarly with friends and family to a lesser degree.
I just had a guy offer to trade my MacBook for his used AirPods and I felt like barfing 🤢
Surgical stuff is also being cleaned/sanitized/disinfected a whole hell of a lot better than you could clean an earbud.
