It's highly unlikely that any wireless exposure long-term is good for you. Personally I would never wear any wireless headphones. I do not use a cellphone either for the same reason. But is that what you really wanted to hear?

Most people only like to hear someone telling them that the people selling you these gadgets confirm they are safe. And that is indeed what they do. Only if you read the fine print of your cellphone will you see that if you touch your head with the phone while talking, you have in fact made them free from any liability of damage. So there's that perhaps to take into account.

Apple airpods use higher quality EMF designed in California. It will kill you, but you have to have a monthly subscription for it to be painless. All other brands use cheaper EMF that will kill you with varying degrees of pain but you usually only have to watch ads or pay once for it.
