I have to agree with the last two posts about the Bose....
Swombat the current model circulating is called " Bose x" which comes with noise cancellation, wireless ops, and wait .....much more features like digital stereo sound yep that's true .....U will have to literally call the US to get any details as Bose in OZ won't have any idea what ur talkin about.
Sorry I know I have the # somewhere but can't seem to find it ...However ring directory assistance and u should have a # ..that is if u wanna Bose Headset..
Good Luck and happy flyin...
