Easy Setup 
Plug
Plug the Relay into an in-flight entertainment system (use the adapter if necessary) or any other audio source with an AUX 3.5mm audio output jack.
Power
Turn both the Relay and your headphones on (some earbuds – such as AirPods – need to be powered off in order to place them in pairing mode.)
Pair
For first use, the Relay will automatically enter pairing mode. Place your headphones into pairing mode as well.
Play
Keep the devices close together and they’ll connect. Press & hold the main button until the LED flashes blue & red to connect another pair.
Will this work with a regular TV?
As long as your TV has an AUX audio output jack, the Relay will work with it.
Will I get audio lag or lip-sync delays with my headphones?
Your headphones must support either aptX Low Latency or aptX Adaptive in order to eliminate audio latency. Please note that most true wireless earbuds (such as AirPods) do not currently support these audio codecs.
How are the volume levels?
You should be able to reach sufficient volume levels by adjusting the volume on both the Relay, your headphones, and / or the audio source.
How long does it take to fully charge the adapter?
It only takes 1.5 hours to fully charge the adapter.
Can I connect my phone to the Relay via Bluetooth?
No, as a transmitter, the Relay is designed to only connect to audio devices (such as your headphones or AirPods) via Bluetooth.

Customers say
Customers find the Bluetooth adapter works well on international flights and is easy to set up and connect, particularly with Samsung earbuds and airplane viewing systems. Moreover, the battery lasts well on long flights, and customers consider it a great device for air travel. However, the sound quality and connection receive mixed feedback – while some report great sound and flawless Bluetooth connection, others experience wonky sound and connection issues. Additionally, audio latency is also mixed, with some noting no noticeable delay while others report significant timing imbalance.
