Dual Link Included Adapter Extended Playtime

Dual Link

The Relay’s intuitive LEDs allow you to easily connect up to two audio devices and share the audio.

Included Adapter

Connect to any plane with the double 3.5mm adapter – no need to purchase separately.

Extended Playtime

A battery life of up to 20 hours provides sufficient battery life to last you through any flight.

Easy Setup


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.


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.)


For first use, the Relay will automatically enter pairing mode. Place your headphones into pairing mode as well.


Keep the devices close together and they'll connect. Press & hold the main button until the LED flashes blue & red to connect another pair.
