Other AirPods Pro Features
AirPods Pro are also expected to be “longer-range.” Rumors suggest that they’ll be able to work further from an iPhone than past AirPods. More than anything else, this hints that they could feature some type of upgraded wireless chip (perhaps with other benefits).
There are plenty of other potential features rumored to come to a future version of AirPods, such as advanced health sensors like a heart rate monitor. Those are certainly possibilities for AirPods in general, but we haven’t seen any specific rumors suggesting they’ll specifically show up on AirPods Pro.
