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

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.

Excellent little item that worked well with my AKG headphones and was super easy to pair. Excellent battery. Lasted a 12hr flight with lots of charge left. Has two pin adapter for airplane socket too if needed, all packaged in a little pouch for convenience. Highly recommend for the price.

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.

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!

I fly long haul 2 to 3 times a year on business and have been meaning to buy something like this for awhile. After reading the reviews et cetera, I opted for this one. As long as you follow the very clear instructions to turn off Bluetooth on your phone or any other device before trying to pair, it was easy to set up. I flew with it yesterday connected for the entire flight and it worked perfectly. It had hardly used any of its battery power still having four of the five lights when I charged it. So far so good.

Long term use review. I bought this adapter nearly 2 years ago and have used it multiple times on long haul flights on various different airlines. It's so easy to carry, always connects first time to my Bose noise cancelling earbuds and the sound/sync is perfect. So much better than airplane headphones and wires. I'm often asked about it on flights and am suprised that more people don't have them. This has been one of my best Amazon purchases.

Brilliant with no lag. Works great on a tablet for the plane.

Really handy to have a Bluetooth transmitter for in-flight entertainment so you can use your wireless earphones/headphones. The option to pair a second device and watch a film together is nice too, though we haven't actually done that beyond testing. Some airlines have a 'watch together' feature though, which eliminates the need, and better syncs video too so you're still watching your own screen, and have independent volume control. Pairing was smooth, but (re-)connecting can be a bit flakey, and a dance of disabling Bluetooth on your phone or whatever else might've connected. To some extent that is just Bluetooth, but there's not really a good excuse for it not taking over once the audio's playing. Nicer feel & design than other Avantree models, and the inclusion of a short USB cable to both charge and take audio from IFE is a nice touch.
