content: I recently bought two pair of these noise cancelling headphones to replace earlier headphones we had bought from Radio Shack. We wanted to upgrade quality while not going through the roof in price. I did a fair amount of online research and decided to buy the well regarded PXC 300s and am not disappointed at all. My wife and I use these for traveling. We travel overseas and try to be pretty light, so the ability to fold up and become quite compact was a strong plus. Comfortable to wear - not too much pressure on the head. Good noise suppression. I'm sure that we would get better fidelity (and bulk) with Bose, but at barely $100 per pair these are an excellent choice.
