These come with no manufacturer packaging but are brand new! (Box was damaged).  Check out these Sony Headphones.  I own a pair, and I love them.  In fact, I wouldn't fly without them.  I have yet to run the battery all the way out... IT LASTS FOREVER!  And the noise canceling is a godsend on flights with babies or young kids.  It's much better than earplugs.  Plus, when you need to hear something you just touch the headphone and it turns off the noise cancellation and turns on a mic so you can hear what is going on around you.  It's perfect for when you are at a loud gate at the airport but still need to hear the announcements.  Get these headphones at a great price! Retail is $249!!!!
