Just recently I bought a pair of Logitech 980409-0403 noise canceling headphones: Newegg.com - Logitech 980409-0403 3.5mm Connector Circumaural Noise canceling headphone and so far I love everything about them except when I use them at home and I turn on the noise canceling I hear a small background music which I assume is radio. Is there any way around this? Thanks!
