Not much benefit from any kind of engine and noise when people walk or cycle with earphones. That is very usual view for me nowadays. Worse if they also stare at they phones too - blind and deaf at will.
I've said this before in comments but I just really have trouble understanding people who can walk--especially in cities--with earphones. I know some are less isolating than others--some like the pass through mode on the Airpod Pros. But I don't even really like earphones on a forest path much less a city street.
I guess it's somewhat a matter of what you're used to. I grew up pre-Walkman and have just never gotten into the habit of wearing earphones like that.
