iPhone 16 line is probably the only line that I think that they came out with that you can update reason being is they're going to have the AI integration with the camera and that is something that you can only get with the iPhone 16 upgrade you will not be able to have it if you have the 15 or the 14 um it's not a software update for the watches however the watch OS you definitely can update that bad boy if you have the latest version um if you have the ultra 2 the previous Ultra 2 or if you um have the ultra one I would still upgrade if you have the ultra one just because they are no longer making that one so at least if you already had the the ultra 2 the previous one keep it update the watch OS and you're good to go um regarding the headphones the only one that I would upgrade is the max which I am doing um that's a type-c uh change so if you know you know for the Pro Line you definitely can keep that bad boy cuz they're going to be uh software
