Hi, just got an AirPods Max. When I tested it for the first time, turning on and off noise cancellation worked fine. However, when I tried again, a very loud hissing sound was generated from the right side. It was so loud that it could damage my hearing. Tried that button a few more times and every time I pressed it, I got very loud hissing sound. What is wrong? Did I get a defective device? At this price range, this should not have happened.
