Important Notes

This product does not support audio output to wired headphones or speakers; it is specifically designed for wireless headphone transmission only. The AirFly SE must remain within reasonable Bluetooth range of your connected device to maintain stable audio playback. Always ensure the 3.5mm audio source is powered on and outputting sound before pairing. The included USB-C cable allows for continued use during charging, but actual usage time may vary based on volume levels and environmental interference.
