Query: great on a plane, especially for the price

I bought these to use to watch movies on the plane, and when I first got them, I tried them at home and couldn't figure out what the big deal was about. Basically, if you turn on noise-reduction when there's no noise, there's no benefit.But on the plane, that's a different story. At first, I forgot that I had to turn the noise reduction on, and I was disappointed that even at full volume, I couldn't hear the movie. Then I remembered to switch the noise reduction on, and WOW, what a difference! That's what this headset is made for.Overall, I agree with Aaron J. Thomas' review: they are very comfortable, I like the choice of various ear plug sizes, and the price is right. The noise-reduction switch unit is large, but hey, the things are so inexpensive, it's not a big deal. I can't afford a lot for fancy schmancy noise cancelling earphones, so these suit me just fine.
