The difference between the two is that if you wear glasses the Voyager ages for you because the legend fits behind the ear and gets in the way of all glasses also the Voyager edge has a much greater range it says its good for only 33 feet but I have used it at farther distances up to 60 they won't advertise that but I've done it the Voyager edges case has a built-in battery pack so if you're not using it at the time you just snap it into its case and it recharges for up to 6 hours of use again it is an incredible device if you tap the switch twice it will call back your last number and it ties into s voice or Google Voice on your phone for text messaging phone calling and looking up maps it is excellent it's the best Bluetooth device I've ever used hands down. And the way it attaches to your ear is comfortable and you won't even know it's there. No kidding you'll think you're going to lose it because you just don't feel it.
