I need to buy a noise cancelling headphone. Its just impossible to listen to anything while on a 747. Which headphones would you recommend? I looked around on CNET and the best one seems like the Bose Quiet Comfort II, except that they cost $300 and are rather bulky. http://dw.com.com/redir?edId=3&dest...tml?tag=tm&oId=4614-5-107393&siteId=7&ontId=5 If you have used any noise cancelling headphone, please post your opinions/recommendations. (I'm sorry this is not directly Apple/MAC related, but apple does offer the bose headphones on their online store.) Thanks for your valuable feedback!
