Product Description

Frequently Asked Question

Q: Why is this more expensive than similar products?

A: At Avantree, we use Qualcomm’s premium Bluetooth chip to deliver better sound, stable connection, lower latency, and stronger compatibility. Many lower-cost alternatives use basic chipsets with limited performance.

Q: Can the Relay pair with my phone?

A: No, the Relay is a transmitter, not a receiver. It is designed to send audio from devices like airplane entertainment systems to your Bluetooth headphones. It cannot connect to a phone.

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

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.
