Avantree Relay - Airplane Bluetooth Adapter for 2 AirPods or Headphones

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.

Does a fantastic job with portable DVD players. I was worried it would sound bad but it sounds no different from devices with Bluetooth. It also works with mp3 players. I was confused in how to set it up but website was clear even down to the brand of headphones. Great little device

Worked a charm! Glad I read reviews and chose this money saving option vs the highly marketed "name brand" version. I had no issues pairing these with the Shokz Open Fit Pro's. I did not have to unpair the ear buds from my phone. I used these on a 14+ hour flight with zero issues. On the way home, I used them for 20 total hours of flight time on 1 charge. No lag, no audio issues. Would buy again. The range was pretty good. A couple of times, I headed to the restroom and forgot to pause my movie. I got in that little plane cube and was startled to realize I was still listening to the audio from my seat screen. So, good range with no interference. Was honestly surprised how many people are still using the free and terrible plane earbuds.

I bought this item as well as the Twelve South Airfly Pro. I tested them at home before my international flight. I sent the Airfly back as this item was just as good, if not better, at a lower price point. I didn't notice any lag at all with this item (neither with Airfly to be honest). I detected very little background static, if any (less than the Airfly). Battery life was great... fully charged, I used maybe half of its power on an 8 hour flight (it went from 4 lights to 2 on the indicator). (Tip: Remember to turn it off after your flight. I forgot upon arrival to my destination and it was completely depleted when I checked it before my flight home). I bought two of these, one for me and one for my husband. Our only gripe is that it is a touch finicky when trying to connect to the our headphones (he has Bose over the ear, I have AirPods Pro 1 and 2 and connected both of them before flying). But we still loved them. I definitely recommend turning your bluetooth off on other devices (ie. your phone), as it does cause interference as the instructions state. Once we turned off our phones bluetooth during connection it wasn't too bad. Both my AirPods Pro and AirPods Pro2 connected just fine. And when one died during my flight I just took out the other pair and it connected to the transmitter. We both liked them very much and will definitely be using them going forward! SO much better than the freebies they give you!

I recently purchased this relay for my long trip and it was great! Even the two passengers next to me asked for it and they will buy it too. Easy to connect to my headset via Bluetooth. I will use for all trips now. Great product.

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!

I appreciate how easy these are to use and connect, however, the quality varies. They’ll be working fine for a while and then suddenly it gets very scratchy and I have to completely disconnect/reconnect to the sound quality back. This happened three times on a four hour flight.

Good Bluetooth adapter. It comes with different adapters. I haven't had to use it. However, it looks like a good device. It's easy to use and is the right size.

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.

Always syncs up well and has a good battery! No complaints.

Funcionó justo como esperaba, no duden en comprar el artículo.

Arrived safely works well

I picked up the Avantree Relay mainly for use on flights, and it’s been very reliable so far. Setup is simple and quick, pairing easily with my Bluetooth headphones. Once connected, the audio has been stable with no noticeable dropouts or lag, even during long flights. Sound quality is very good for a Bluetooth adapter, and it works well for movies, TV shows, and general audio without sync issues. The adapter itself is compact and lightweight, making it easy to carry in hand luggage or a pocket. Battery life has been more than sufficient for long journeys, and I’ve been able to use it across multiple flights without needing to recharge in between. Build quality feels solid, and the physical controls are easy to use without needing to look at the device. It also works well beyond flights — I’ve used it with gym equipment and other non‑Bluetooth audio sources with consistent results. Overall, this is a well‑designed, dependable Bluetooth adapter that does exactly what it’s meant to do. A great option if you want wireless headphones to work properly with airplane entertainment systems or other wired audio sources.
