Relay Bluetooth adapter for aircraft or audio devices with aptX Adaptive & Low Latency. The included dual 3.5mm aircraft adapter makes the Relay usable on any aircraft, regardless of which audio output jack you will find. Also works with any device that outputs audio via AUX, such as tablets, PCs, fitness equipment, etc., and can be connected to any Bluetooth headphones or earphones (e.g. AirPods Pro 2). With support for the aptX Adaptive and aptX Low Latency codecs, the Relay transmits high quality, low latency audio when used with the same headphones. The Relay also uses Bluetooth 5.3 technology, which enables stable and reliable connections. With the Relay's intuitive LEDs, you can easily connect up to two audio devices to your Relay and share audio with a second person. With up to 20 hours of battery life, you can get through a flight, a movie marathon or anything else. If the battery ever runs out, just plug it in and keep using it while it recharges. Relay's built-in controls and handy LED indicators let you adjust volume, pair, reconnect, clear pairing history and view battery level.

Used it on two long haul flights with my Bose Ultra headphone, great for watching movies and no issue with latency. It's small, uses USB-c to charge and lasted no issue on my 12h flights.
