Yesterday I bought some Ear Force X3 headphones for my Xbox and I've had mixed results. When I first hooked it up to my Samsung HDTV, I was very disappointed. It had a very noticeable buzzing noise that made the headphones basically unusable. I was almost ready to take my headphones back to the store to replace them with the wired X1's, but I figured I'd take them to my friend's house and try them out there. When I played with them there, the headphones were amazing, and I didn't hear any buzzing noises at all. When I got back home, I hooked the headphones up to my system again, and the buzzing noise was there. This leads me to believe that something in the room is interfering with the infrared signal. When I walk around the room with my headphones on, at some parts the buzzing noise gets significantly louder. Does that mean anything? Also, if it is in fact something interfering with the infrared signal, how can I identify what's causing it and stop it from happening?
