The Avantree Relay is a Bluetooth transmitter designed to connect your wireless headphones to in-flight entertainment systems. It plugs into the standard 3.5mm audio jack found on most airplane seat screens, allowing you to use your own noise-cancelling or preferred headphones instead of the airline-provided ones.
Verified user reviews highlight its ease of use and sound quality. One reviewer on Amazon noted: 'Easy to connect to the airplane viewing system and my Bose noise cancelling headphones. Great sound quality for the long plane trip. Comes with all needed accessories and adapters which was great.' The device includes a built-in battery and supports dual-device pairing, so two people can share one transmitter.
The Relay is compact and lightweight, making it convenient for travel. It also works with other devices that have a 3.5mm audio output, such as gym equipment or older audio systems. As of May 2026, it remains a popular choice for travelers seeking to improve their in-flight audio experience.
