There is no noise cancellation at all. It feels like I don't use the headphones, because I can hear outside sounds as they are. I am not pleased with the performance, and would not recommend this product to anyone.
No, I would not recommend this to a friend.

Hi Bilge,
Thank you for your review. We would like to inform you that these headphones don't have a noise cancellation feature, furthermore they also don't have a noise isolation since they are on ear and not in ear.
