I got my wife a pair of Airpods 3 and her feedback was "they feel like they'll fall off anytime because they're so big and don't fit my small ears very well". I tried them on and I told her they felt fine. For some reason my wife doesn't like ANC products, as she's able the hear the high pitch noise coming out of the ANC when it's active, so I am not entirely sure if I want to get her the ANC version of the Airpods 4, but the cheaper one maybe the way to go for her.
Anyway, it was very nice of you to test the watch under water and ice :D it reminds me the days when I was in school volunteering to help people out at the cafeteria. With no gloves, and just an ice pick, I was splitting ice blocks into smaller manageable chunks behind the fruit stand... after 30 minutes of that you really can't feel your fingers anymore. Safety regulations sure have come a long way :D
