## Description

Avantree Relay - Bluetooth 5.3 Adapter for Airplanes with Qualcomm apt-X Low Latency Adaptive Support. Wireless Audio Transmitter for 2 Headphones or AirPods. Perfect for in-Flight Entertainment

Review: No problem with connection. Works as advertised - Bought it for a recent long airplane ride from Dubai to Canada. Was Flying on ITA Airways. Didn't need to use because ITA allows direct bluetooth connection, but I tested it on my laptop and it worked as stated. Only problem is trying to remember the directions to connect/pair since I don't use it very often.
