This review is from: Audio-Technica ATH-ANC33IS Active noise cancelling in-ear headphones with Remote and Mic (Electronics)
I wanted some headphones for using on a long flight to America, they worked brilliantly cutting out most of the extraneous engine and cabin noise when switched on, so much so that I ended up using them as earplugs when I wanted some sleep.
