So they're the best and they may not be the worst. I took them overseas and I was thankful they were there but it does not eliminate 95% of anything. The cord was not a problem for me as others have stated. I liked the length. Wish it had a volume button on the headphones to adjust sound. Battery life was fantastic. I took a 15 hour flight to and fro without having to place new batteries. Probably good for a lot shorter flights. Very compact!
