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

This Relay kit has become an essential part of my travel kit. The Bluetooth adapter is fantastic, especially for long flights and the sound quality is top-notch, giving clear and crisp audio without any noticeable lag.One of the best features is its battery life – it lasts throughout my long flights (14hrs plus and it barely went down one bar) without needing a recharge. It's easy to connect if you follow the instructions and worked perfectly with Apple AirPods.Pleasantly surprised, and definitely made long flights more comfortable!

I have been needing a device like this that works, this one actually does work with Apple and Beats products as suggested (other products do not) The sound quality and range of the transmitter is impressive. I don’t like in a mansion or a castle but I can roam my home with ease and keep the connection.I highly recommend this product if you value quality and ease of use. I’m currently using the transmitter on a TV so I can work at the computer and listen/watch TV while I work.

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.

This was bought to connect earbuds to the flight entertainment systems, and works really well. It's also handy to use by one (or two people) when you have a TV that other people around you don't want to hear, like in a hotel room.It's easy to connect your headphones to and once connected they do remember the headphones and connect automatically.Sadly, it may have a limited life as the latest planes allow Bluetooth connectivity and in effect replace this lovely little gadget in the air.

Great battery life, easy to pair to two sets of headphones. Charge time is good and good range for the Bluetooth.Didn't pair with phonak hearing aids which is a shame but not main reason for buying and not a problem for me.Fingers crossed the build quality will stand the test if time but would buy again if any issues.Bit of a lag on tv but nothing too bad, used mainly for sport so doesn't need to be perfectly synced.

Does the job well, I had a very slight perceptible delay but then my over ear headphones are not the top of the range. I did forget to turn it off so when I got on my return flight the battery was dead, but I was happy to find out that I could charge it on the plane really fast, and I could use it while charging, so even better! love that it comes with a little zip bag, supper easy to connect. Happy with the purchase.

It's apparent that people leaving five star reviews here have a pretty low bar when it comes to quality - latency on this thing is huge, 400ms, and distorts MASSIVELY when there is any loud noise (even when you turn the volume down on the unit - RIGHT down, til it's barely audible) - sent back

I have flown on BA and United. Both times the supplied two pin adapter has not matched the adapter the airline used. I have tried inserting directly into the hole without an adapter. But i dont find this works reliablyImho a broader range of teo pin adapters are neededIts a good product. But it can be a tad fiddly to set up. The online instructions accessed via a QR code are very helpful. But remember to do this early. You may struggle with internet access once onboard
