4 Better Water Resistance
A prominent part of Apple’s teaser video included a woman running through water while wearing her headphones. The latest Apple events have taken a significant amount of time to point out the water resistant features of the iPhone XS and XS Max, so it just makes sense that the AirPods 2 would have similar water resistance capabilities. That doesn’t mean you’ll be able to dive headlong into water (well, it may possible, but please don’t try it at home either way), but I think we can safely expect extra rain, sweat, and “oops-I-dropped-one-in-the-toilet” protection.
