Excellent noise cancellation. Black over-ear wireless headphones with charging cable and carrying case. - Brand: SONY - Model: Wireless Headphones - Accessories: Charging cable, carrying case, airplane adapter - Color: Black - Design: Over-ear Thank you for viewing. I have used these for about two years in total. The noise cancellation feature is particularly excellent, and I found them very useful on airplanes and when I wanted to concentrate at my desk. I am selling these because I am upgrading to a new model. Thank you.
