Query: Great Sound!

They work great! I ordered these headphones so that I could watch TV (which shares a common wall with our master bedroom) after my wife retired for the evening.I wasn't prepared for how much better everything sounded with the headset compared to our "open air" system.After trying them, my wife agrees, and we are planning on buying another set for her (even if she isn't trying to sleep).
