i think u can use ordinary head phones but u cant hear great. i think the head phones cost us about £5 each, plus u get and adapter with them so u can use them in your home stereo or walk man.
I was given a pair of fancy headphones designed for use on planes - they filter out the background roar of the plane . Hence why I am keen to use them instead of the airline ones.
Thanks again for taking the time to reply - appreciate it.
