THEY ACTUALLY WORK!
On a recent trip from the US to Australia I used these--and to my surprise--they really work! No, they don't "totally" eliminate all noise, but any noise there was from people talking, to airline intercom announcements, etc. did not affect me while I was trying to sleep. And what was equally important to me, was the fact that I didn't have anything "over my ears" that I had to lay on. That made it comfortable for sleeping. I will definitely be using these over and over again!
