Normally I like koss Porta-pros or Sennheiser earbuds (CX300's) for portable use but I picked up a pair of these
Sony MDRNC7 noise cancelling headphones and for the price they are hard to beat.
The key here is you said for use on a plane. While passive 'phones sound better in everyday use, the noise cancelling feature is really, really easy to get used to on a plane. Seriously, they are even useful without music playing just for the reduced noise floor.
Now, I'm wondering what a "real" set of noise cancelling headphones can do but since we only fly maybe three-four times a year, I'd really have to justify that outlay to my cheap self.
Oh, they also come in white.
