I’m going on a flight in a few weeks, and want some good [though low budget!] headphones. I’m wondering what’s the difference between noise cancelling and noise isolation headphones? Would noise isolation headphones be just as good at disguising aircraft engine noise?

I heard noise cancelling needs batteries, major turn off? And which one do you recommend, is there any good brand that’s cheap?

Noise-isolating headphones simply passively block outside noises from reaching your ears by their mechanical construction. Sticking your fingers in your ears is a noise-isolating technique. Ear buds with a nice tight fit work similarly.
In contrast, noise-cancelling headphones use active electronics to “listen” to the noise around you and play and inverted signal through the headphones to cancel out the unwanted noise.
Most commercial “noise cancelling” headphones use a combination of both isolating and cancelling techniques. It turns out that noise cancellation works better at low frequencies and noise isolation works better at high frequencies. Using both together gives you good isolation across the whole frequency range.
