re: Suggestions on Noise-canceling Headphones

1) evaluate your actual need for noise-canceling, realising it adds nothing to the sound and costs both more money and batteries forever, and that since you prefer over-the-ear cans, you do get a fair bit of shutting the outside world out.
2) inner fidelity'a wall of fame is a great place to start. They've got reviews apart from the wall of fame as well. You can also scroll down and check out different classes (wireless, over the ear, sealed, in-ear, etc)
3) good luck.
