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.

I have an old set of SONY noise cancelling "ear buds" and a set of Etymotic Research.

On flights to asia (I go 5X/year) it's the sony's... in the car (when being driven) it's teh ER's (at home it's the Stax).
There is one. Just got Amazon catalog. Philips HN-110 for $39.99. For the money its worth a try.
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.
