When the AirFly doesn't appear to transmit audio, it is often because the headphones are already connected to another device. To resolve this, turn off Bluetooth on all nearby devices to which the headphones have been paired, including your phone.
If that doesn’t solve the problem, reset the AirFly. To do this, hold the Reset button down for 5-10 seconds (for AirFly Pro, make sure the bottom button on the side is toggled down to TX mode). Once successfully reset, the AirFly light will be flashing Amber & White.
Finally, reset your headphones, then re-pair them to the AirFly.
