it states that the headphones are active noise canceling but are actually acoustic noise canceling. also the manual states that you can adjust the equalizer in the app but you can not. i have not made up my mind on returning them or not.
I bought them a year ago and like within a week of warranty being up they broke lol but other than that they have been good

I got these as a gift and the are just unreal, sound is so crisp and they do amazing with the noise cancellation. You can't go wrong here. The new colour schemes are also amazing.
