Apple products offer a wide range of capabilities thanks to its hardware and apps. Among those apps are ways to hear better.
For those wearing hearing aids made by major manufacturers Oticon, Resound, Starkey, or Widex, they can use the Apple Watch app.
And those people not wearing hearing aids can use Apple AirPods.
One of the reasons that people who are hard of hearing don’t wear hearing aids is that they don’t want others to think they are “over the hill”. But Apple AirPod users are unlikely to feel that way, nor are Apple Watch wearers (there’s an April 5, 2018, YouTube on CNET called “Can hearing aids be as hip as the Apple Watch?”)
