Here’s a description about the Bose QuietComfort 15:

You’ll love what you hear. And what you don’t. Don’t let noise get in the way of your favorite entertainment. Bose QuietComfort 15 headphones fade unwanted noise, bringing out the natural sound and detail of whatever you listen to. With exclusive Bose technologies, your music and movies never sounded so good.

You could also get another 1500 miles if you buy the product. This is a $300 headphone product, so hey even too rich for my blood. They say you can try QC15 headphones for 30 days, risk free.
