Sometimes when you are trying to pair your headphones with something new, an existing device might be getting in the way. For example, trying to add your headphones to your phone after your BT01 transceiver or iPad after your phone. Sometimes other bluetooth devices might also interfere.
Where possibly, try turning the other device off or moving to a different area away from other Bluetooth items to see if your headphones will then go into pairing mode. With reduced interference, the Audeara headphones typically pair much more quickly.
