I have come in a little late for this, but if it helps, there are a number of US cities that have Bose Stores. I oicked up a great bargain iPod Dock from the Bose Store last year at the Las Vegas Premium Outlets. Much cheaper than EBay or other stores. It is senseless to pay Australian prices for Bose products if you can get them from the US.
I am going to Hawaii again and will checkout the Bose Store there at Ala Moana for the headphones. I currently have Plantronics HP which are bluetooth and very good as I can also use them for handsfree on my phone, but are not noise cancelling.
I do believe though that Bose do not make bluetooth noise cancelling HPhones.
I really like my music and movies to have good sound when flying, so NC would be the way to go. I expect that you could get Bose HP for under $US300 at their outlets.
