I've got a pair of noise canceling panasonic in ear headphones, but they have that battery noise cancellation thing which tugs on the headphones. No good for boarding. The original Icons seem very good, because they have the double headbands, and are flexible. I wear a helmet, so they seem like they will barely interfere. On the other hand, I like the purple model of the Icon 2, but the headband doesn't seem very compatible with the helmet. Without a helmet, and just hat and goggles, I can imagine them staying on like a magnet. With a helmet, I'm not so sure. Should I go for a dull black colored Icon model, or would the Icon 2s be fine for helmet use?
