ok, i think this is a much easier fix or
maybe this is the real way to setup the headset...
1. add device or start searching bluetooth devices from computer.
2. then hold the headset ON button until the green light turns ON and fades away and the blue light starts blinking very fast. (hold for about 5-7 seconds until the blue light starts blinking)
(now the pc can detect the device and just install it)
