I currently have the Sirius Sportster boombox in our house. But as the antenna is connected to the outside it is difficult and not convenient to move this device around the house. I am considering getting the Sony Wireless 900 MHZ RF Open-Air Headphones from Best Buy. Does anyone have any experience with these or other wireless headphones in a house with a Sirius boombox or docking station. Is the reception static free? Does other household appliances/electronics interfere with the frequency? Any answers would be appreciated.
