I use it on a Homepod Mini to toggle different lights and a fan. In my previous apartment I used it to control a window AC. Sometimes I tell it to pause my AppleTV if I can’t find the remote quick enough. I use it with FindMy when I lose my keys or bag or whatever else (I have a lot of AirTags). Other than controlling devices I mostly use it for weather reports and timers.
For me, the switch to wireless earbuds has been mixed. Not having the cord get tangled and caught on things is nice, but I’ve come to dislike how precarious AirPods can feel (to me at least).
I’m always worried about them falling out of my ear and landing in a gutter or a toilet; I have to be careful pulling them out of their case and putting them back because they’re easy to slip out of my fingers; I always have to remember to keep the case charged; if I want to take them off temporarily, I can’t just drape them around my neck (at least not without 3rd party accessories but then you have to take those off to charge so more hassle). I feel like I just can’t be as spontaneous with them as with wired ear buds.
