Etymotic Research Noise Isolating Headphones

These are the best earphones I've ever owned. They are noise isolating to a fault: I can't wear them when I'm walking around because I won't hear a car. But for working in a cafe, or when my wife wants to watch TV in the room next to my study, or when I'm trying to sleep on an airplane, these things are the absolute best. Worth the money. And, currently on SALE at amazon!
