Review: Ideal for flying with bluetooth headphones; a well thought out product - Why did I buy this product? Because I make international flights on a regular basis. For travel, noise canceling headphones are a must-have, but most are now bluetooth. Unfortunately, most cattle class seats have infotainment systems that only provide mini-jack outputs. Enter this device as the perfect solution! At least in my opinion. This device allows me to plug-in to the output jack on an aircraft without the inconvenience of wires. It has several domestic uses, specifically provided a bluetooth interface to older audio equipment, PC's that don't have bluetooth, and (some) tablets. Does it work? Yes, no reservations. Fully charged, the battery was only 50% drained at the end of a 10 hour flight to London from Phoenix, AZ. I used this device in conjunction with my iPad mini, the aircraft infotainment system and even my PC at home. Binding was fast and effortless. Recommend you read the instructions because although binding and unbinding is easy (and works) the unit itself has a minimum of controls and you need to know what you're doing! I really can't speak to quality or range, but at least up to around ten to fifteen feet it was working fine, and sound quality was excellent without drop-out or interference. Can I listen to music while the unit is attached to a charger? Yes you can. This was a worry for me, especially since I forgot to recharge before the return trip. So I attached to a USB-C power bank and absolutely no problem, throughout charging, the unit worked fine. BTW, many airlines seem to be banning the use of power banks on or onto their aircraft - just another nuisance to check on before you fly! Do I know how much power is left? Yes, there are 4 white LED's which tell you how much charge you've got on the device. The top-most illuminated LED flashes until the next level is reached or the unit is fully charged. Finally, can two people listen to the same audio? Yes, my wife and I watched a video on the plane, with both of us wearing Bose NC headphones in bluetooth mode. The unit provides two, simultaneous links so for me that was the final box ticked. Some widgets are hard to use, but this one is well thought out and easy.
Review: Works perfectly for downloaded movies on laptops for long flights - This relay works great with our laptops! The instructions were concise, clear, and both sets of our ear buds were very easy to pair and use with it. We can now watch our downloaded movies on our flights with each of us having our own set of earbuds instead of having to share one set, lol. We especially appreciated how the instructions boldly point out to turn off our phone Bluetooth during pairing because that causes 90% of problems...sure enough, that instantly worked. We also like the included charging cable, plane adaptor and sturdy zippered carrying case.

### ⭐⭐⭐⭐⭐ A great little gadget!
*by T***E on May 26, 2026*

OMG! This little device is awesome! Recently flew on Delta and American. This adapter worked well on the large planes. The short flight taken on a smaller, commuter plane didn't offer seatback entertainment. It was so old, Wi-Fi was absent too. Initiating the unit requires a QR code reader to access online instructions. The first synch was a little challenging, but once it was successful, all other pairing sessions were much faster. The audio transfer was wonderful. Listening to headphones without a cord made the flight more enjoyable too. Definitely worth the purchase and highly recommended!
