Good point. I was confused because my other headphones when they are in pairing mode a blue light flashes repeatedly, but after reading the manual for the XM5 this means that are not connected not that they are in pairing mode, and as you said for pairing mode you have the press the power button for 5 seconds, the problem is that when I do that the headphones shutdown, May be there is an option to change that, I will check it out.
