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

Pros: Connects to AirPods & airplane seamlessly, did not run out of charge for 10+ hours, great audio quality on airplane.Cons: None that I can think of.I only used this with one set of AirPods so the 2 sets feature untested. That being said, this is now a STAPLE in flying for me. AirPods cancel out the buzz of the plane, and this transmitter lets me listen to the movie perfectly! No issues, easy set up. Already recommended this product to friends & family!

I purchased this repeater for my upcoming trip to Florida and paired it with the Bose Quiet Comfort headphones. Initially, I had some trouble pairing the device; however, as the pairing instructions recommended, I made the connection after turning off other Bluetooth devices.Before the flight, I fully charged the device and my headphones. During the 5-hour flight, the repeater worked quite well, not once dropping the connection or experiencing issues. Not having wires hanging around ready to tangle you to the seat was immensely liberating.The sound quality was good, and I did not notice any lag. After the flight, the repeater was still close to full charge, so I did not charge it for the return flight home.Overall, I am pleased with the device. The easy-to-read charge level is a nice touch, and it works well with my headphones. Pairing with two Bluetooth devices is a nice addition for those traveling with kids.

Worked great on my flight to Japan, no lag with my soundcore open ear buds. Sound quality was great, connection was easy and the little pouch for all the accessories is cute and compact. I'll definitely be using this little gadget again and again.

used this as a connection to an electronic piano for my wife. She connects to it and has headphones on so no one but her can hear her playing (she's weird like that :D ).Had to purchase an adapter for the connection that the piano had but other than that it works great. Sounds great and is easy to setup.Only drawback is that there is a VERY slight delay between the press of the key and the sound in the headphones. Not sure if it is the device or the piano

I have a Cardo Packtalk helmet intercom system. The "half helmet" kit does not come with speakers, you have to plug your own 3.5mm jack in for speakers. Instead, I plugged this item in and then Bluetooth connected my Aeroplex aftershocks Bluetooth headphones to it.. BOOM!! It also works with my Samsung Galaxy Buds!. Tip- Your phone cannot be connected to the headphones! So either turn you phone Bluetooth OFF or delete the Bluetooth headphones from your phone before trying to pair them with this device. They reliably connect every time and were super easy to set up. The device is also nicely assembled and has a solid feel. The farthest I've needed to be from the device is about 6 feet and that worked great, so decent range.

This works flawlessly!!! It set up correctly on the first attempt (rare!). The two prong adapter was a life saver, as I was able to use my own headphones instead of the ones provided by the airline. The previous adapter that had I bought hardly ever worked, so this was a welcome surprise. It works flawlessly and made my in-flight entertainment enjoyable. I cannot emphasize how happy I was that this was easy to use and that it actually worked. The adapter is a game changer.

The device looks sleek and seems to work as intended. However:1) The "User Manual" included in the package does not provide instructions on how to pair the device with the airpods, which is not an intuitive procedure and, in fact, I had to use an AI tool to find out how to do it.2) Despite the description on the Amazon site that claims the device has "low latency", there is a significant time lag between the input signal and the sound that can be heard at the airpods. This means that it cannot be properly used mixed with the real time sound in the same location, like, in example, for listening to the sound from a TV, while others listen to the direct sound from the speakers of the same TV. Doing that creates a significant and disturbing echo created by the direct sound coming from the TV mixed to the sound transmitted to the airbuds from the device. Same problem would exist when using the device as a wireless in-ear monitor for stage performances. In fact, the performer would hear a mixed echoed sound coming from both the stage speakers and the airpods connected to the device.

Works great, easy to set up, clear sound. One design issue I found. The plug is 90 degrees from the receptor hole which causes the unit to stick out quite a bit. Worked well the first flight when next to window, was broken the second flight when in aisle seat and the window passenger got up to go to restroom. They hit the unit and snapped the plug. If there was a 90 degree plug on the unit it would not stick out so far. That is the only downfall, only was able to use it for two flights, well, one and a half.
