Agree with the first part, very important! Not the second, however.

I joined my local fitness gym some months ago and use it to connect to people in the small town I moved to. Almost every time I'm there I manage to chat to someone briefly, and 50% of them have earpods in. Most of them now look up and greet me when we pass and multiple have up to me on other days to chat afterwards.

It's a skill and part of that skill is being able to give people an out of the chat if they don't feel for it, not interrupting at a bad time (mid set in a gym setting). My starter is usually a quick question with a "thank you so much, I'm new here" and if they reach for earpods to put back as they say you welcome, perfect you don't keep going. For the ones who want to chat keep them off and respond or ask something in return.

So headphones/earpods can be a barrier but for me it's a useful barrier and a clear signal, which helps both parties.
