It seems that Apple has learned the art of teasing its fans and prolonging their waiting. It waited a month after its iPhone XS event to reveal its new iPad Pros. And now it might be waiting for yet another month to bring out another expected product, the next-gen AirPods. It might be close to launch, though, if certification and trademark filings are any indication. And if those sightings are correct, fans might be looking at a rather sophisticated piece of fitness equipment they can put in their ears.
