Syntech Airplane Bluetooth Transmitter Receiver with Extra Dual 3.5mm AUX Adapter, LED Display Low Latency Dual Link Bluetooth 5.3 headphone Adapter for Car AirPods Wireless Headphone

I bought two of these units for use on a long haul flights, one for myself and one for my gf. They worked brilliantly, allowing us to use our own noise cancelling headphones instead of the poor quality ones provided by the airline. The Bluetooth adaptors are supplied in a neat pouch and come with everything needed to connect to the airline entertainment system plus a usb charging cable. Set up was a breeze with the connection made in seconds on first use. Switch the unit on, set to transmit and put the headphones into pairing mode. The name of the headphones appears on the screen of the adaptor and the connection is made. For subsequent use, the connection is made as soon as headphones and adaptor are switched on. Sound quality is very good. I listened to Talking Heads and AC/DC and could hear a level of detail comparable to when the headphones are connected directly to my phone. Volume was adequate. I watched several TV programmes and films including Gladiator, Napoleon and 32 sounds. Latency was minimal, but just about detectable if I looked for it closely. It was not an issue for normal viewing. The documentary film 32 Sounds provided a good test of performance. The film contains demonstrations of binaural sound effects and these worked perfectly through the Bluetooth adaptor. Battery life is excellent. I used my unit on two consecutive flights totalling around 17 hours with an estimated listening time of 12 - 14 hours. Two bars remained on the battery indicator after this time. I gave both units a brief charge and they were ready for the return journey. These units can be used to stream music from a phone a device with line in. This might be useful in future for music streaming in a hire car. I have not tried this yet so cannot comment on this feature.

Works perfectly and with the little lcd screen you can select the item to pair to, which is a must, if like our house, you have a lot of bluetooth items. Handy little hard travel case ideal for when we go on holiday/travel. I’m not able to comment on the sound quality as it is for my teen daughter to watch tv with, but she’s not made any complaints.

Works OK and does what it should. Construction and connection: Construction is solid. Case does not flex if pressed. Connections and TX/RX switch are recessed so they won't get caught accidentally. While the USB charging lead is adequate, the 3.5mm audio connection lead is, for me, way too short. As the headphone socket on my TV is rather far back at the rear of the unit I found myself having to strain to plug the short lead in. Fortunately, I had a long spare lead which helped. Setup and use: Very easy to use. My judge of an items useability is whether I can set it up and use it without referring to the manual too often and I found the unit easy to get working. Took less than a minute to fathom out how to turn it on and pair it with my JBL headphones. Once I learnt how to do it I can now set things up in a few seconds. However, I think I would probably have to use the instructions for some of the more advanced features. That said, the instruction book is good and understandable. Last. but not least, the display, whilst small, is very readable and gives good feedback. Sound quality: Good and clear. The product claims 'low latency' and I found the claim accurate - with reservations. There is a VERY slight lip synch lag - nothing too bad and is barely noticeable if listening to direct TV broadcasts - and I have noticed that this is a feature of many transmitters. However, watching recordings from a Freeview recorder via HDMI produces a very noticeable lag. Bluetooth connectivity is very stable. I was able to wander around the house and go in the garden without too many problems but I did find some breakups in odd locations. I did have one issue with the left side audio developing a slight hiss but I think that may have been a problem with my headphone as turning them off and on again cured the problem. Overall, I think this is an adequate transmitter that is well made, does what it should and does it passably well. It's easy to set up and use, gives a reasonable connection and works with minimal fuss. The only thing I cannot comment on at this point is battery life as my TV has USB out and the transmitter is under constant power. Given the price, quality and ease of use I would say it's OK value but the recording audio lag does let it down somewhat.

These work perfectly on long-haul flights - flew over 120 hours last year and they’re still going strong. Great if you’re the type to forget to unplug your wired AirPlane headphones (have been known to accidentally destroy some 😬). Would recommend!

Great little device for allowing wireless connection of non-wireless devices to my Apple AirPods. I used this device to link to the screen on a Boeing 787 flight to Mexico and the performance was great with clear sound and no noticeable lag. A small case adds to the convenience of the package.

Apart from being compact it’s worth nothing. My main purpose of purchasing this device was to cover up its ultra low latency feature. Unfortunately it’s seriously lacking the features mentioned i have tried across various bluetooth headphones ranging from versions 5.0 to 5.4 at some point or the other i have faced extreme latency on all devices. Apart from headphones i have tried using it on speakers and trust me it’s even worse. Leave latency its not even covering the range of 0.5 meter from the speaker it loses the bluetooth signal. Honestly for me overall it has a compact design but is a worthless product

Works brilliantly on the plane and also at home. Very small in size but great value for money, not much audio Lag, when watching a video, buttons are good size considering the size of the device, noise level is good. Would definitely recommend

Would not recommend this product , tried for hours to connect but without success Returned for refund

Ich habe mir diesen Bluetooth-Transmitter speziell für Langstreckenflüge gekauft, um meine kabellosen Kopfhörer auch im Flugzeug nutzen zu können – und das war eine hervorragende Entscheidung! Der Transmitter ist kompakt, leicht und einfach zu bedienen. Er wird einfach in den Doppel-Klinkenanschluss im Flugzeugsitz eingesteckt (Adapter ist meist dabei), per Knopfdruck in den Pairing-Modus versetzt – und schon war mein Kopfhörer verbunden. Die Verbindung war stabil und die Tonqualität wirklich gut, selbst bei Filmen mit vielen Soundeffekten. Was mir besonders positiv aufgefallen ist: Kompatibilität: Funktioniert mit allen Bluetooth-Kopfhörern, die ich ausprobiert habe (AirPods & Sony). Akkulaufzeit: Reicht locker für einen Langstreckenflug – ca. 15–20 Stunden – und lässt sich per USB-C leicht nachladen. Design: Sehr klein, passt problemlos in jede Tasche und stört nicht am Sitz. Fazit: Ein praktisches, durchdachtes Gadget f%C3%BCr Vielflieger und alle, die nicht auf Bluetooth-Kopfh%C3%B6rer verzichten wollen. Funktioniert einwandfrei, ist einfach zu bedienen und spart Kabelsalat.

Excellent Transceiver (utilisation en avion). La batterie tiens très bien la charge!

Lo estoy usando para poder conectar altavoces y auriculares BlueTooth a un viejo proyectos. Funciona perfectamente y buena calidad de sonido.

Super fonctionne très bien et très bonne autonomie pour des vols long courriers

Convenient small size and the rubberized protective cover is great. But the screen came loose when i removed the screen protector film. And the latency... It's really noticable, so don't trust the "low latency" claim. Sure, all Blurtooth devices have a latency by natur, but this one is worse than the rest of my bluetooth devices.
