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 have used this device several times. It is exactly what I was looking for. It flawlessly connected to two seperate bluetooth speakers, it provides audio volume control, and is rechargeable via USB 3.0. It is extremely lightweight. It allows me to use an old Samsung Note 4 (which thankfully has an audio jack) as a music source to two speakers that are far apart. The sound is superb.My partner and I are ballroom dancers that always record our practices. We wanted two speakers. One we use with a sound-proofed headset microphone to externally supply the music to the video (bypassing the internal mic that picks up too much background noise). The second speaker we keep at a low volume near us so as not to disturb others. We use a mobile phone with a camera to record the video while supplying the music directly to the phone. This device allows us to seperate the speaker to the camera phone, the phone playing the music, and the speaker that we dance to by as much as 30 feet. I am very happy with the product.

Works great! Used for a transatlantic flight, and fit the bill perfectly. Great that it includes the little adapter thingie needed for some Aer Lingus planes (didn't fly any other airline just yet).

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

This might read as hyperbole, but this thing has kind of changed my life.I bought this to use on a recent trip to Belgium, and it worked like a charm.As the directions will make very clear, you really need to do some setup at home in terms of bettings this thing connected. And once you do, it works like a charm (pro-tip: make sure your phone, computer, or iPad is not competning with the bluetooth connectivity). But once you get it paired, simply turn on the device, get your headphones hot, and then plug it is. I had no issues on the plane and it was great to watch a movie on the seatback screen without the $0.50 headphones they give you.But when I got home, it hit me that I might be able to hook these into the A/V receiver (with a plug adapter) to watch TV while on the treadmill (I had a previous bluetooth adapter and I was so disappinted iwth it that I seldom tried to use it). Just as on the plane, this connects quickly, has NO lag, and allows me to walk or run (or use the erg) with my good workout earbuds.I have now unpaired these from my phone, for I am only going to use them with the device.In short, I have been very happy with this and strongly recommend it.

Used this with BW Px8 headphones for some air travel. Worked great. Was really easy to setup. Battery lasts a long time. Autoconnected to my headphones after initial pairing.

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.

This works great and is good value. I had no problems pairing with AirPods Pro 2. Sound quality is good enough for a non-audiophile using this primarily on airplanes. Did not experience any lag relative to the video. Most airplane IFE systems have a 3.5mm port, so this plugs in directly. Some of the airplane seats have dual ports, so this set comes with a 2-port adapter. However, you don't actually need the adapter as plugging the one port in works fine and transmitted sound to both L and R AirPods. The unit compact, has a sliding on/off button, and charges by usbc (so no extra specific wires needed). Comes with a nice zippered pouch to keep it altogether. Overall pleased with this, and better value compared to the AirFly option, especially if not flying every week or even every month.
