im flying by myself the first time and i got my self a pair sync by 50 (http://www.amazon.com/SYNC-Cent-Wireless-Over-Ear-Headphones/dp/B006BUN8NO/ref=sr_1_1?ie=UTF8&qid=1348437601&sr=8-1&keywords=sync+by+50) i want to know if im allowed to bring these with me while im going through checking. theyre wireless so i was hoping just putting them around my neck and when u have to go through the metal detector put in the tray and back on when im done. thank you
