A:Answer I found that voices will be muffled, but will still be able to hear them. The other incidental noises will be cut out. For example, on an airplane, when I turn them on without listing to any music all the sounds of the airplane itself go away, but unfortunately you can hear a baby crying or a loud passenger talking. It does reduce those sounds, but you can still hear the people and baby. When it gets like that, I put some relaxation music on really low, just enough to block out the voices and it seems to work.
