You don't even know that the guy with earbuds has anything turned on. You don't know the volume level if he does. You don't know that he even has hearing; perhaps he's deaf and has earbuds so that you don't try to talk to him. You don't know that he doesn't have full awareness with any volume of music. People assume that there's automatically a problem, and that really is a case of choosing to believe something.
I've said it a couple of times, I judge someone's potential distraction and skills by observing them as I approach. Earbuds, helmet, clothes, type of bike, none of these common sources of judgment enter into it - just their positioning and movements in context with what's going on around them. I don't choose to believe anything at all about their headphones.
I rode about 60 miles yesterday and passed many cyclists and pedestrians wearing earphones without issue, but there was one jogger who wearing them who didn't respond to my bell and decided to cross from the right hand side of the trail to the gravel track on the left hand side of the trail just as I was passing her. I had to brake, swerve, and ring my bell repeatedly to avoid her, fortunately I was going a little Under 10 mph because of prior experiences.
It was my awareness of the potential issues, and my extra caution for those who wear earphones that prevented a collision.
