Relay Airplane Bluetooth Adapter for 2 Headphones

Airplane Entertainment, Two Person Shared Listening, Gym and Treadmill Audio, Handheld Gaming Consoles, Tablet and Laptop Audio, Wired to Wireless Upgrade

Overview

The Avantree Relay is a compact 3.5 mm AUX Bluetooth transmitter aimed at travel and gym use. Plug it into an airplane seatback socket, treadmill, tablet, PC or handheld console and it sends that wired audio to your own Bluetooth headphones or earbuds, with dual link so two sets can listen to the same source at the same time. Avantree rates the battery at up to 25 hours of play time from a 2 hour charge and the operating range at up to 33 ft (10 m). It runs Bluetooth 5.3 on a Qualcomm chipset and supports aptX Adaptive, aptX HD, aptX Low Latency, aptX and SBC, with published latency of about 40 ms on aptX Low Latency and 80 to 110 ms on aptX Adaptive. It is transmit only, so Avantree states it cannot be used as a receiver to play phone or tablet audio through wired speakers, and the company recommends a dedicated TV streamer for continuous home television use. A single and a dual airplane plug adapter and built in volume controls are included.

Key Highlights

  • Published latency of about 40 ms on aptX Low Latency and 80 to 110 ms on aptX Adaptive keeps lip sync usable on in flight movies
  • Dual link pairs two sets of Bluetooth headphones at once, so two travellers can share a single airplane seat screen
  • Up to 25 hours of play time from a 2 hour charge covers a long haul flight and the trip home on one battery
  • Qualcomm chipset supports aptX Adaptive, aptX HD, aptX Low Latency, aptX and SBC, so it uses the best codec the paired headphones accept
  • Ships with both a single and a dual airplane plug adapter and adds on device volume controls, so it fits standard and twin prong seat sockets
