Turn on the transmitter and enable Bluetooth pairing on your headphones; the transmitter can connect to one or two Bluetooth headsets. Charge the transmitter via the USB Type-C port or store it in the charging case to recharge the internal battery. When using away from the aircraft, plug the 3.5 mm jack into any device with a stereo output to stream Bluetooth audio from that source.

Recommendations

For best results, fully charge both the transmitter and the charging case before use. When low latency is required (video or gaming), choose aptX Low Latency if supported by your headphones. Keep the transmitter and headphones within 20 meters and avoid obstructions for stable Bluetooth connection.
