Noise-cancelling headphones recommendation


Can someone please recommend an "effective" noise cancelling headphones for less than $40 using for 14-hour trans-atlantic flight. I did a search on Amazon and read the reviews, but all the lower priced noise cancelling headphones reviews are mixed at best. Please share your experiences.

Just have done alot of reading on headphones and I decided on a pair of Shure E2C which have received good reviews. I paid $75.00 delivered and should get them tomorrow. Drop me an email and I can provide you with the website that I ordered from. The Shures will be used with a iAudio U2 mp3 player for the gym and hopefully will sound good. The recommendation for the Grado SR60 is a good one, although they are not considered "noise cancelling" headphones and are a bit uncomfortable. I own a pair of Grado SR80's and love the sound, but again the comfort is lacking.
I just picked up some ultimate ears super.fi 3 studio ear canal headphones and I love them. They're $99, and they work about as well as ear plugs on reducing noise. The backround noise is cut down dramatically with them on, and I find myself listening at much much lower levesl than I used to... which is a very good thing for your ears. For noise reduction realistically they work about as well as the Bose ones do even though they're passive, on top of that they cost 1/3 as much and don't sound like ass. They're certainly worth considering.

Thank you for all advices. After some searching around I purchased the Maxell HP-NC3 Lightweight Noise Canceling Headphones from buy.com for $20. I only use it for a one time trip to Asia on the airplane so hopefully the noise cancelation circuit will do its job.
I'm a big huge fan of Grado headphones and don't personally find them uncomfortable--actually, the SR60s with the full foam cups are the most comfy Grados I've tried. They're a bit forward, but they are clean and resolving enough that I take the tradeoff.

The problem with the Grados is they're the anti-noise cancelling headphone. They're open-ear so they will throw a small amount of sound out and around you, while letting some sound in. I like them on trains and planes because the environment is usually noisy enough that you won't bug anyone with them, and you can still hear a steward/ess approaching as long as you're not rockin' out too much.

Let us know how the Maxells work out. The price is certainly right!
