Cellular connectivity gets a meaningful boost from 5G support, with reviewers describing it as useful for leaving the phone behind and handling calls, messages, or downloads on the move.
Materials feel appropriate for the price, with the aluminum bezel helping the Pro look and feel more premium than simpler models.
Materials are good for the price, centering on aluminum and improved Ion-X glass rather than the more premium finishes found higher in the lineup.
Menu navigation is commonly described as easy to learn and straightforward once the button layout is familiar.
Menu navigation is easy and quick, with reviews noting snappy movement through apps and an interface that is simple to learn.
Phone-based music controls work well and are easy to access during workouts, but they rely on a connected phone.
