Apple AirPods are not anymore dangerous than other earphones or earbuds and I have a pair of them myself and love them.
I love the sound quality and the audio experience and wireless option of the Apple AirPods.
I've tried other wireless earbuds but the AirPods are the best wireless earbuds and are well worth the money.
The Apple AirPods could become dangerous if you don't remove them when you need to pay attention and hear things outside.
So you could become distracted by the AirPods and potentially walk out into the street and get hit by a vehicle but other than that they're not dangerous.
