There you go. Quite comfortable, don’t have to stick them inside your ears, and still allows you to perceive the sounds around you.

In the spirit of fairness, I’ll also share the cons from my experience: First is battery life isn’t as good as headphones. That’s somewhat obvious as they’re much smaller, but they will still last you the whole day so not really an issue for hiking. Second one is that because they don’t block outside sounds, they’re not appropriate for audiobooks/podcasts while walking in the city. Again, not an issue for hiking.
