Avantree Relay - Premium Airplane Bluetooth Adapter with Advanced Qualcomm Chipset, 2 Headphones Support, 25hrs Play Time, aptX Adaptive & HD Audio Transmitter for Airpods, Bose & Travel Flight

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.

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.

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.

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.

Easy to set up, good connectivity, worked well during my recent flight.

Works like a charm! Came fully charged right out of the box, and the setup was effortless. The instructions were clear and easily accessible by simply scanning the QR code with my phone. It connected to audio on the first try and performs significantly better than any others I’ve tried. Excellent product — I’ve already recommended it to a friend and plan to buy another one for my wife to use on our upcoming trip, especially for the airplane.

The transmitter requires devices compatible with aptX adaptive, low-latency codecs. Otherwise you will experience very noticeable audio delay. Download and read the manual to research compatibility before purchasing. My need was to connect with a basic Tribit Maxboom bluetooth speaker. The Relay charged, successfully paired with the speaker, and operated as described in the manual. But, the lack of codec compatibility means a disturbing delay.

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.

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.

RECOMMENDED..

La batería es de las que más dura. Funciona perfectamente.Lo volvería a comprar.

muy buena compra, justo lo que necesitaba.
