These headphones are excellent. My only qualm is that there are times when they will have some static if I don't keep my phone out. When I try to keep it in a purse or pocket the earbuds go in and out. For the most part I love them. Most other ones I have used say they offer noise reduction but don't. These stand up to the test. They actually cancel out so much that I have to take them out my ears to hear people speak even when I am only wearing one side. Comes with a convenient charge case which makes it so much easier to keep up with them and prevent loss.
