Hi, I have a black pair of beats by dre studio 2.0 wired headphones and they have Adaptive Noise Cancelling. I have had other beats in the past that have not had this. Can someone please explain in normal practical terms what this is exactly and how it works. I am getting a sort of speaker like sound that you get if you have speakers up really high but nothing playing, basically like white noise. as soon as i turn it on I get that white noise, then if I play something i cant really hear it. Is that the adaptive noise cancelling? Thanks
