You hear the dumbest line in your life... it happens.
You hear it again, you think what a weird coincidence.
You hear it from 1/2 the population, you have to fucking ask. How the FUCK does this bullshit make sense to people? Headphones add noises over already existing noise. They do not subtract. Also, if you set them loud enough to outscream the environment, you will go deaf in 3 days.
@LukeAlmighty I'd still say that's headphones, afterall they play whatever sounds the user needs to shut off ambient noise
maybe it would help to think of it as reverse glasses: yeah, someone still sees with eyes in the end, but it's not a mistake to say that someone can't see without glasses even if it's not true, strictly speaking
+ if you're wearing headphones, more considerate normies might not bother you when they otherwise would
