I couldn't see this belonging anywhere else but here. I'm considering picking up some noise cancelling headphones, for use watching movies etc on my laptop. My concern is using these overseas, is it a good idea? As I understand it, they block out low frequency noise (engines, air conditioners etc) so alarms etc can still be heard. That being said, in the event the world turns upside down I don't want to be the guy lounging in my room glued to The Jersey Shore (remember that scene with the old lady in Mars Attacks?). Anyone use these overseas and if so, did you encounter problems?
