I talked to a friend regarding this and he suggested you try the SennheiserHMEC-26-KP ANR headset, he has two sets and he says they are the best money can buy. He also said they were a little pricey at first but the initial investment out weighed the overall cost.
I found a website that sells them along with many other brands so take a look for yourself.
