EchobreakerI have these headphones and love them. I use them on flights all the time and am very impressed with the quality of the noise reduction. I have had them for about two years now and haven't seen any reduction in battery life.
jesuguruI have only ever used them wirelessly. They sound good to me, but I am by no means a headphones connoisseur. I don't have good enough hearing to need anything better than my earpods most of the time.
