Avantree Relay - Airplane Bluetooth Adapter for 2 AirPods or Headphones

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.

I bought the Avantree Relay for a return flight with Virgin Atlantic and used it with my Sony WH CH520 wireless Bluetooth headphones. It worked brilliantly on both flights. On the outbound flight, the aircraft had Bluetooth connectivity, but it kept disconnecting, which became really frustrating. As soon as I plugged in the Avantree Relay, my headphones stayed connected for the entire 11 hour flight without a single issue. On the return flight, I was on an older aircraft that did not have Bluetooth at all, so the Relay was essential. The airline does provide wired headphones, but the sound quality is not great, and I much prefer using my own headphones as they block out more background noise and are far more comfortable. I only charged the Relay before each flight, and the battery easily lasted the entire journey with plenty of power to spare. It was simple to set up, reliable throughout both flights, and made a huge difference to my in flight entertainment. I would definitely recommend it to anyone who wants to use their own wireless headphones when flying.

Edit - surprisingly good customer support from a customer service agent named Rosally, despite my issue with the shattering audio jack - I received a replacement unit within a couple of days after submitting a report on their website. I guess I now have a new device that I will take a lot of care to avoid stressing the metal of the audio jack on! The tech was working great on a couple of flights until yesterday when I was using it an air steward lightly knocked the device while putting down my in flight meal tray. The audio jack shattered leaving small pieces of metal in the jack socket, my meal and scattered across the cabin floor. So no in flight films and no inflight meal for the last 10 hours of my flight as a result...

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.

Works perfectly. I connected it to the emirates headphone jack and was able to sync the audio from my movie and have my partner watch and listen simultaneously. Great device for if you travel frequently long haul and like to co watch movies with someone. It’s also useful for if you wanna share music with others on the go - however remember - if you have an iPhone with USB C - you need an aux to USB C adapter !

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 airpods pro 2, its temperamental to connect the airpods even worse when I paired my wife airpods pro 2 and share the audio of the movie we were watching. Sometimes after a 30-40 minutes it can be heard like a crackling noise or one ear dropping out, turning it on and off again fixes that. Not sure how it works with other brands im sure it will be less problematic with other brands that is not Apple. For the money I'd expect better but it's easily fixed by cycling the power. Im returning the product as I need somethat will work well with Airpods pro 2. Comes well packaged and has a handy little pouch for the bits.

Purchased for my 9 hour flight to Nashville from UK flying with BA. the device worked really well with my Samsung Galaxy Earbuds - sound quality was even better than my phone! I would highly recommend reading instructions and playing around with it before flying. Sometimes you have to wait a few minutes for it to connect to your phone when on plane. However great quality.

Very easy to use and reliably works on most/all flights I’ve taken. Sometimes I do have to check how to re-pair the headphones when I can’t get them to switch from my phone. Would definitely recommend for anyone wanting to use their own Bluetooth headphones without a cable.

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.

Always syncs up well and has a good battery! No complaints.

Funcionó justo como esperaba, no duden en comprar el artículo.

muy buena compra, justo lo que necesitaba.

Koppelt sich stabil mit 2 AirPods gleichzeitig, ohne Aussetzer. Akku hält wirklich fast den ganzen Langstreckenflug. Steckt fest am Klinkenanschluss, kein Wackelkontakt. Praktisches Gadget für Vielflieger.
