I carry cheap earbuds I got off aliexpress in my backpack and offer them to people who are listening to music or tiktok without headphones.

I have a nonzero accept rate!

But you really have to be in the right frame of mind. If you approach someone in anger, they'll pick up on it and mirror you.

The best line I've found so far is, "I know Apple stopped giving out earbuds with their phones; would you like some?"

I appreciate your empathy for the fellow human. Even if it's "undeserved" it still makes things better for everyone involved.
