>I have a bluetooth device (headset) that I added to the Windows 7 Bluetooth devices. So obviously Windows "detected" this device when it was on. Now when I turn the headset on, I tried to listen to a youtube but no sound is sent to the headset. The headset actually works with iPhone. And to test it, I turned the bluetooth off on the iphone, just so it was be interfering. What do you suggest?

Bluetooth devices has to be "matched" in order to communicate. You can usually do this from Windows' Bluetooth setup.
