I bought these a week ago and the noise cancelling is perfect. When I need to tune out the rest of the world due to getting overstimulated I can push a button and everything goes quiet.
Ive only had these for about 4 days. Biggest disappointment and a total waste of money. No matter what i tried they would connect and then disconnect about 4 seconds later. Not my phone because everything else works on it. My soundbar does wonderful as well as my car stereo so its definitely the headphones i bought. And of course with it being an electronic item they will not exchange or refund me for the purchase. Very disappointed.
