The Zulu seems to be generally reckoned to be slightly better than the Bose. We have 2 Zulus in our Sportcruiser. The sound reduction is awesome. When you put them on, ambient sound is squashed. They are easy to hook up with Bluetooth. I find them slightly hot and sweaty, but they do exactly as it says on the tin. If you can afford it, Zulus, then Bose (from what the magazines say). The perceived noise level leaves you completely unfatigued. BUT, if you are price conscious and only do limited flying, these very expensive headsets are too much of a luxury. Don't become ANR fascinated- it is not the be all and end all of aviation. They are not worth missing out on a lot of flying for.
