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. Whatever is causing the interference is close to either the base unit or the headset, so the only thing I can recommend is the old fashioned trial and error. If you can, try moving the base to a different spot, even if its just the other side of the TV. If the base unit is near a clock radio, try moving that.
