Whenever I have to travel in a bus or flight, I make sure I have my iPod and Panasonic headphones tucked into my travel kit; but everytime I wish I had a pair of wireless headphones that can easily sit behind my head while I sleep and listen to my music, without all that wire-entangling mess! So I was plesantly surprised to find that Opera Headphones using Kleer technology are designed for just this, and are perfectly matched for all the Apple iPods!
