Query: Worst Headphones EVER!

These headphones are unbearably uncomfortable, and they barely do any for noise-cancelling. They pinch the tops of your ears, and the way they sit on your head, you can not sit back while wearing them. I tried to wear them on a plane, but had to lean forward to do so. The noise cancelling only works a tiny bit, as I could clearly hear ALL noise around me. They turned the airplane noise into slightly quieter airplane noise. Not worth it!
