I know this is an old thread. I just want to make sure anyone who reads this is as informed as they can be. Personally, white noise also irritates me. Bose for example uses white noise or something like that to block out other noise and that irritates me, too. And studies have shown that exposure to long term white noise can impair your hearing. I'm also sensitive to anything that goes into my ears, so IEM's are just no option. I opted for noise ISOLATING headphones. Do your research. For me it had to be the best i could get.
noise isolating headphones are also cheaper. think like hearing protection headsets that people working with loud machinery and shooting would wear. they make ones that can play audio too! noise isolation is good for loud sounds and people yelling whereas noise cancellation is good for ambient hubbub type noise. some people are more sensitive to one type or the other, and i'm more sensitive to loud noises. however, i like having both options for different situations because i'm sensitive to noise in general.
active noise cancellation headphones put out their own sound waves 180 degrees out of phase with the incoming waves and thus cancel each other out. passive noise isolation headphones just absorb incoming sound waves. that's basically the difference, and, why active noise cancelling headphones are so pricey.
