My wife & I own two pair of Bose noise cancelling headphones between us, bought mostly to cut out the noise on the 8 hour flight from London to Orlando. They are fitted with miniature JAP plugs which fit just about any muisic device - ie ipods, sony walkmen, cassette players modern aircraft music/movie sound outlets, laptops etc. The leads on our Bose can be detached from the headphones if you are not listening to music, so that the leads do not get tangled up in anything. The miniature JAP plug is just about universal today and most headphone plug into amost any device. The Bose are supplied with adaptors to fit the larger JAP plugs found on hi-fi amps and adaptors to fit older style aircraft sound outlets.
