In a world full of marketing hype it's always good to find something that works as advertised. The design of the Voyager 510 is well thought out. It's comfortable, but you still know it's there. For me that's a very good thing. I don't want it falling off only for me to realize it well after the fact. However, due to its great design I don't think it would fall off easily. Volume is excellent, once you're used to the controls they are excellent, clarity of what you hear as well as how others hear you is excellent. Overall solid purchase.
