A:Answer If you get a buzzing sound from the headphones, it means that something nearby is causing interference. Unfortunately, the are a lot of things that may cause interference. A radio, phone, streaming stick, or even a microwave oven can cause interference. However, in your particular case, the problem may be easier to solve. How do you watch Netflix? If you have something like a Roku or Fire Stick, or a Google TV unit, that might be the issue. Try moving the base unit away from whatever you use to watch Netflix, even if you just move it to the other side of the TV.
