Only they’re not noise canceling. What noise canceling headphones do is use a microphone to pick up ambient noise and then play the inverse wave of that same sound through the headset along with the normal audio out put. What happens is when the opposite waves hit they cancel each other out. All he did was make some ghetto earmuff style headphones out of some cheap on ear ones. Not impressed.
its 20 bucks man… what the hell do you expect?
its impossible to cancel noise anyway. any budding physicist should know that! lol
