Avantree Relay - Airplane Bluetooth 5.3 Adapter with Qualcomm aptX Adaptive, Supports 2 AirPods or Headphones, 20H Playtime, 3.5mm AUX Jack Wireless Audio Transmitter for Planes, Airline, Travel

I picked up the Avantree Relay mainly for use on flights, and it’s been very reliable so far. Setup is simple and quick, pairing easily with my Bluetooth headphones. Once connected, the audio has been stable with no noticeable dropouts or lag, even during long flights. Sound quality is very good for a Bluetooth adapter, and it works well for movies, TV shows, and general audio without sync issues. The adapter itself is compact and lightweight, making it easy to carry in hand luggage or a pocket. Battery life has been more than sufficient for long journeys, and I’ve been able to use it across multiple flights without needing to recharge in between. Build quality feels solid, and the physical controls are easy to use without needing to look at the device. It also works well beyond flights — I’ve used it with gym equipment and other non‑Bluetooth audio sources with consistent results. Overall, this is a well‑designed, dependable Bluetooth adapter that does exactly what it’s meant to do. A great option if you want wireless headphones to work properly with airplane entertainment systems or other wired audio sources.

Works really well, fantastic for a flight and good price too, sound quality is good and it’s super compact and durable, no noise and it’s very versatile.

Works really nicely. Instructions are clear. Thanks for thinking to include a nice little travel bag. Would be five stars, but for the packaging unrecycleable at least in my location.

Simple to set up with AirPods, no lag in my tests. Product feels qood quality, comes with carry purse, two pin adapter and usb to usb c charge cable. Ours came fully charged. Sounds great too.

Finally got to try this out on four long flights to Auss and back. Paired effortlessly with mu Bose NC headphones with no percevable delay to the sound. Made long flights much more enjoyable (?) With clear sound without the wire getting in the way. I was also surprised at how long the battery listed- not on the full flight but quite a lot of the 23 hrs each way and didn't run out!! Definitely a great buy and is now permanently in my headphones case. Didn't try pairing a second device, will try this next time. Small case to put it in is good too.

I recently went on a long-haul flight with the Avantree Relay, and I must say, it transformed my travel experience entirely. Upgrading my Bose QC20 wired earphones to a Bose Ultra Earbuds with this compact Bluetooth adapter proved to be a winner! This is a great travel companion, effortlessly connecting my favorite earbuds to the in-flight entertainment system. The audio quality was excellent, with virtually no delay thanks to Bluetooth 5.3 and Qualcomm aptX Low Latency technology. I didn't try it, but I appreciated the convenience of being able to connect two headphones simultaneously, perfect for sharing a movie with my travel companion. One of the standout features for me was the long-lasting battery life. Throughout my entire flight, the Avantree Relay kept me connected. The zippered case is a convenient bonus too! Overall, I couldn't be more satisfied with the Avantree Relay. It's a good-quality, affordable solution for wireless audio connectivity on planes. Highly recommended!

Got this for a long haul flights and just had chance to test it. So it works ok, easy to pair. Weird things happen to my beats in ear headphones after a 30-40 minutes like a crackling noise or one ear dropping out, turning it on and off again fixes that. For the money I'd expect better but it's easily fixed by cycling the power. Comes well packaged and has a handy little pouch for the bits. Not great, but good enough for the use it'll get, definitely worth £10, but not £30

Takes a bit of setting up, but once sorted brilliant bit of kit. Allowed myself and my wife to watch films on my tablet with our bluetooth ear buds at the same time.
