Question about FiiO BR13

The FiiO BR13 is a Bluetooth audio adapter and does not work directly with the Apple AirPods as a receiver for the AirPods themselves. The BR13 is designed to act as a Bluetooth receiver for traditional audio systems and devices by receiving Bluetooth signals and converting them into analogue or digital audio signals.

However, the Apple AirPods are Bluetooth transmitting devices and can be connected to the FiiO BR13 when used as a Bluetooth source. This means you can connect the AirPods to your smartphone or tablet and then connect the smartphone or tablet to the FiiO BR13 via Bluetooth to transmit the audio signal to the BR13.
