Update…I sent my headphones through Best Buy, like Apple instructed me. After a week without the headphones I get a message that my equipment was ready, when I go there, the report from Apple is that they couldn’t reproduce the problem. I was furious, they sent them back exactly the same!!!! Worst service ever. Then I call customer service using the headphones and the guy starts telling be that he can barely understand me, when I took the noise protection off, it was clear. Even their own customer service people could notice the problem, but apparently the apple technician doesn’t even know what they are doing. My equipment was purchased in November, this is too soon to be giving so much problems. Then the person on the phone started as usual, looking for ways to blame it on me, like if maybe was my phone, or the noise cancelling had too much around and had to produced that white noise to muffle the noise. I told him I have tried them with different devices and at the moment I was locked in my car alone, plus if is the NC system working, why would it produce the noise only in one ear? Is ridiculous at this point. I went again to best but and sent them again. Second week without them, an almost $300 equipment, that many clients are having the exact same problem, but they act like is isolated and a user error. Apple is trying to get another class action with the way they are treating this.
