Ive got a couple of questions that some of you guys could help out with: Do you think passive noise isolation headphones would be a better for a long haul flight? Can you use your own headphones on a flight? I was going to get some active noise cancelling ones like the Bose quiet comforts, but I've been put off by some of the things I've read on here. Even though I don't personally believe they would have any negative effect, I'm leaning on playing it safe and getting a pair of Sennheiser HD 280's, which provide 32db of passive noise reduction. Any advice here would be appreciated.
