Recently got a budget of $350, which is quite enough for an AirPods Pro(2nd), but $49 less than an Apple Watch S9.
Current Devices: iPhone X(ios16), AirPods 2, MacBook, and iPad with latest O.S.
I go swimming and cycling a lot and would like to check the data collected by Apple Watch. I usually use headphones in noisy circumstances, therefore ANC is quite necessary.
As stated above, the watch will not work with your phone. You’d need an older used one that hasn’t been updated to watchOS 10. And you’d be stuck on watchOS 9 until you get a new phone.
