But as others have said, I listen at a low volume, and I can still hear almost everything else too, it’s just muffled. I have been doing this since I was little kid (with the big yellow brick sized Sony “Sports Walkman), so maybe I’m just used to it. Then again, I do most things with my earphones in- read, study, work, exercise, type… heck, I have them in now (I am an excellent multitasker). To other’s points that they don’t like riding next to folks wearing them, I guess that is a valid argument, but I very rarely ride with other people. I mapped out my route so that I always have a wide shoulder or am in a bike lane. I don’t know, I guess that you do your thing, I’ll do mine, and we’ll all keep the cranks turning.
