Wearing good headphones in public is dangerous... Yesterday I saw a guy riding a bike wearing a set of DT1350. I almost turned him into a roadpizza as he wasn't looking where he was going, ran a red light and ended up in front of my car... I was only barely able to stop in time, but I had to save those cans from being damaged. I put my car on the side of the road to check if the guy was ok (he did a deer in the headlights kind of thing and turned really, really pale).
He apologized saying he was into his music a bit too much, then mumbled something like "but I doubt you'd understand"... I said "try me", and pointed at my ES10 on the passengerseat of my car. He smiled and said "ok, maybe you do". He didn't know about head-fi, so I told him to check it out. Then we went on our ways again...
