I completely agree that it can be dangerous if you aren't in the correct setting. I was planning to use these when in familiar territory such as the semi private lake that my cottage is on. I wouldn't use them when riding in large open lakes on busy days or in river systems when you have to watch for other boats coming up behind you etc.Wearing headphones while riding makes me nervous. Either they might break with water damage and not being able to hear while riding also doesn't seem completely safe. That's just my 2 cents though.
