Ever go hiking?
On a trail, where you are not subjected to anybody else’s noise for more than a second as they pass you by?
Skiing?
You’re skiing down a slope and a person is skiing next to you with a Bluetooth speaker?
Sit in a park?
Outdoors, where you can put some distance between yourself and them?
Maybe it’s hard to conceive of for some, but the world shouldn’t be shielded by headphones.
You’re right, it’s already shielded by air. The air that you can put between yourself and the other person.
The point was regardless of whatever they’re doing, you are only as subject to their poor behavior as you choose to be.
If you’re not going to do something about it (and please tell me what you would actually do about this beyond complaining on the internet), then your only other choice is mitigation, which involves just keeping headphones with you to block out other people’s noise or learn to find more peaceful spaces.

Sure, if it’s one person. Where I used to live, the nearest park would have multiple groups engaged in loudness wars, each upping their volume in response to the others, so nobody could enjoy the park. Public spaces shouldn’t be held hostage by assholes who don’t understand how to behave in public, to the detriment of everyone else.
As far as what to do, it would be nice if the existing rules would be enforced that prohibit this behavior, but people cry racism for being told off for bringing a massive speaker to blast merengue and dembow in the park and somehow find support, rather than people asking why they’re blasting any type of music in the park to begin with.
