So Far So Great!

5 out of 5 stars

So Far So Great!
Used this for the first time on a recent Delta flight with the Bose ultra open earbuds and it was GREAT. Easy connection. No lag in the inflight entertainment while watching a movie (was a little lag on “announcements” over the PA though.. nothing too annoying). I haven’t used the double end jack so I can’t speak to that. Also can’t speak to longevity. I fly frequently so I’ll make an update in a few months. The color is sandstorm

    Ideal for flying with bluetooth headphones; a well thought out product

    Reviewed in the United States on November 12, 2025

    Color: 1-BlackVerified Purchase

    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.

    These work very well and are a huge upgrade to flying on long flights. No more blasting your eardrums with the cheap headphones they give/sell on the flight. Connection is super easy and consistent. I'm glad I got them.

    So far these are the best. I’ve went through two of the Airfly and struggle to connect via Bluetooth. It was very frustrating but Avantree is easy to pair and very intuitive. I decided to give these a try because i have a pair earphones from Avantree that i use in my home gym and they work and sound great. I hope this helps.

    This pairs well with most devices, but had problems with Bose QC earbuds. Latency is the lowest I have encountered with the right earbuds, but varies with others that are supposed to be ultra low latency. Battery life is around 15 hours between charges. Sounds quality is good.

    Works perfectly for downloaded movies on laptops for long flights

    Reviewed in the United States on January 22, 2026

    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.

    High-Quality Bluetooth Transmitter with Crystal-Clear Sound

    Reviewed in the United States on September 30, 2025

    Color: 1-BlackVerified Purchase

    This is an excellent Bluetooth transmitter that delivers impressive sound quality, not only for headphones but also for portable speakers and even soundbars.

    I tested it with a pair of TOZO headphones, and the sound was crystal clear with no noticeable delay while watching TV. I also tried it with Soundcore headphones, a JBL portable speaker, and my Sony soundbar, all worked flawlessly with excellent audio quality.

    One feature I really appreciate is the ability to switch between two connected devices. With a simple press of the center button, you can easily alternate between them, which is very convenient.

    Yes, this transmitter is priced higher than many cheaper alternatives, but after trying less expensive brands, I can say the difference is clear. Those budget options often struggle to work well with soundbars or portable speakers and don’t offer the same clarity. If you want reliable performance and excellent audio quality, this transmitter is well worth the investment.

    Relay set-up wouldn't complete the connection at first; however, when I first used it on the airplane, it worked perfectly and was easy to use. Just plugged it into the airplane IFE and it connected automatically to my headphones.

    Great adapter.

    This thing is super convenient, easy to pair with, has surprisingly good range, a good battery life, is small and convenient, and sounds great too. Got no static or anything.
    My only relatively small complaint is you can't unpair one of your connections without disturbing the other (as far as I know). You can only unpair both connections or just turn it off long enough to pair to something else. It's not big enough if an issue to be worth dropping a star over, but I thought I'd mention it.

    Der Adapter kam sehr gut verpackt an.

    Die Einrichtung und die Verbindung mit den Kopfhörern ging sehr fix. Zudem ist die Anleitung auch verständlich.

    Im Flugzeug konnten wir den Adapter testen. Ergebnis einfach sehr gut.

    Akku hält lange, Übertragung ohne Verzögerung und in guter Qualität.

    Das verbinden weiterer Kopfhörer auch einfach. Zudem kann man zwei Kopfhörer sogar gleichzeitig nutzen.

    Für den Preis super. Vor allem kann man es ja auch außerhalb vom Flugzeug nutzen.

    Definitiv klare Kaufempfehlung

    Bought it for a recent long airplane ride from Dubai to Canada. Was Flying on ITA Airways. Didn't need to use because ITA allows direct bluetooth connection, but I tested it on my laptop and it worked as stated.
    Only problem is trying to remember the directions to connect/pair since I don't use it very often.
