Product Overview

The Avantree Relay is a specialized Bluetooth 5.3 transmitter designed for in-flight entertainment, featuring Qualcomm aptX Adaptive technology for high-definition audio with minimal delay. It plugs into standard 3.5mm audio jacks on airplane seats and seatback screens, enabling wireless streaming to up to two Bluetooth headphones at once. Built with a durable, compact design, it offers up to 25 hours of continuous playtime on a single charge, making it ideal for long-haul flights. The adapter is engineered specifically for audio sources like airplanes and excludes compatibility with phones, car stereos, or real-time applications due to inherent Bluetooth latency.

Usage

Use the Avantree Relay in airplane cabins to enjoy wireless audio from seatback entertainment systems, eliminating the need for tangled cables. It’s perfect for travelers, couples, and families who want to share movies or music during flights, providing synchronized audio between two listeners. The device is not suitable for real-time activities like gaming, live monitoring, or musical instruments, as Bluetooth transmission delays can affect synchronization. Ensure previously paired Bluetooth devices are turned off to prevent auto-connection issues, and pair with compatible headphones like AirPods or Bose for optimal performance.
