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.

Works well and I can use my old speakers

A very good product for what it does. It is able to connect bluetooth devices that otherwise has no 3.5mm audio plug. With such a little device you can connect your bluetooth speaker by switching a little switch underneath the unit. The display is well though because its actually showing what device is connected to. On the display will appear Rx if the device is receiving signal or Tx if the device. A very good and pleasant experience with the seller professional packaging!. A very good receiver and transmitter! I would like to suggest a little improvement on coverage area and reconnecting possibility because once connected (receiving) if you reach max coverage the device does not reconnect itself. I would definitely buy one or even 2 more of these if the re-connection and coverage improves. I do move a lot around the house and an improved coverage and re-connection capability would make it perfect device for me. The size is small as portable as it can be. Battery life is good, and more importantly for situation when you are using it while stationary IT CAN CHARGE while is plugged in, connecting devices that you'll like to use while is getting charged. A very good function for me. It does take a little while to fully charge but is not the end of the world. It is truth that the device does not seems to show a full battery when is fully charged - it is keep showing a charging state. Again is not the end of the world. you can unplug and plug again then the display will show you a full charged battery. If you are looking for a versatile device hat connects multiple devices either by receiving or transmitting this is for you! Don't get confused - it is either transmitting or receiving only, not both at the same time. Of course is that easy to use I did not even looked in the manual. Any questions, just ask here on amazon. Kind regards, J

If you only require a BT transmitter for use on airplanes there's better options. Some people would say that you must get a Bluetooth Transmitter Receiver as it works both ways and has multiple uses as you can connect it in Bluetooth receiver mode to the input of your sound system, speakers or to your car stereo. Or also use it in Bluetooth transmitter mode, connecting it to the audio output of your TV, PC or laptop, or Airplane entertainment system. However, I only require a BT transmitter for use on airplanes. I had no problem connecting to both Jabra earbuds and Marshall Major IV headphones. I'm no audiophile but I felt there was a bit of latency and the quality wasn't the best. I also didn't like the setup in that you use 3.5mm AUX Adapter, so you have 2 connection points one into the audio out socket and one into the BT transmitter, possibly leading to sound quality degradation and not being compact with lots of dangly bits when on a plane where other passengers want to get in and out of their seats past you is not the best setup.

Really good piece of kit. I bought it to turn my wired headphones into Bluetooth via receiving function so that I can listen in the gym connecting to Spotify via iPhone. You can also use it to transmit , it’s on transmit as default but easy to switch. Battery life is good too. Light and portable. Has a little display , change track and volume , can’t ask for more really.

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

Damit kann man seine Kopfhörer mit Kabel ganz einfach mit Bluetooth ausstatten. Bei mir diverse Beyerdynamics. Der Ton kommt verzögerungsfrei an, eignet sich somit für Video schauen aber auch um in guter Qualität Musik zu hören, wie ich finde. Dazu muss ich aber anmerken dass ich nicht so audiophil bin als dass ich einen störenden Unterschied zwischen MP3 in 320kbps und AAC in 256kbps und unkomprimierter Musik heraushören würde, liegt vielleicht auch am Alter aber ich kann sehr wohl einen besch...eidenen Klang bei der miesen Soundpampe von Spotify in der kostenlosen Version wahrnehmen wenn ich diese über meine Chromecast Lautsprecher dudeln lasse. Als Sender hatte ich bisher keine Verwendung, deshalb kann ich vorerst nichts dazu mitteilen. Das pairing verlief einfach. Es wird Dokumentation, auch in deutscher Sprache, mitgeliefert und eine kleine Quick Info auf englisch liegt nochmal in der Transporttasche um da nochmal einen Blick draufwerfen zu können falls es notwendig sein sollte. Die Silikonhülle passt gut und der mitgelieferte Karabiner ist sauber gefertigt, keine scharfen Kantren oder Grade vorhanden. Fürs erste kann ich nichts negatives feststellen, volle Punktzahl von mir. ================================================================ Liste meiner 1-Sterne-Produkte die von Amazon gelöscht wurden: Haaröl Wachstum 2 Stück 60ML, Haaröl Ingweröl für Haare: https://www.amazon.de/dp/B0D8B3XCT9 fanxiang 10X Schneller USB Stick 512GB bis zu 1050MB/s: https://www.amazon.de/dp/B0DDKTGT4L 1300mAh 9V Lithium-Ionen-Akku: https://www.amazon.de/dp/B0D9YJ45RN vielen Dank, dass du eine Rezension zu ----- hinterlassen haben.

A lot of audio devices, past and present alike, use only wired external audio connections. While "home stereo" systems will often use digital connections or analog RCA jack type connections, smaller (and typically portable) devices use 3.5mm coaxial audio jacks ("headphone jacks") by default, as do many, if not most, computers and tablets. Most more recent ones have pretty good bluetooth available, built-in, as an option. But this is not the case in ever device, and certainly not with many older, but still very serviceable, devices. And note, older versions of Bluetooth are, not surprisingly, of lower overall quality than the more current generations are. From lower audio quality, to more lag, to shorter range... it's been an evolutionary growth from the earliest bluetooth to the most current generation. The market has a lot of one-way bluetooth adapters. I personally own several, both for "audio in" and "audio out" functions. I have a bluetooth-out connected to the optical digital audio out port on a television set I own, for example, and a bluetooth-in device connected to one of the auxiliary-audio-in ports (dual RCA jacks) on my home audio amplifier. But these are neither conveniently portable, nor flexible in terms of what they can do. That's where this device stands out. It's at the latest widely-used bluetooth version (later generations have been developed but not yet really introduced to the market) and is both highly portable and flexible in terms of how it can be used. It basically converts between radio-frequency digital Bluetooth signals and 3.5mm coaxial analog audio plug audio. But it can go either way (though not both simultaneously!), and is not restricted to only one functionality. It works well. I've not experienced any "lag" I can personally detect, though there's probably a BIT of that (more likely than not, measured in milliseconds and thus imperceptable to me or to any actual mortal human!) When used to pick up bluetooth from and convert it into analog audio (for analog-only headphones, etc), the quality is extremely good... indistinguishable, to my ears, from the audio coming directly out through the playback device's analog headphone port to the same headphones. I can't detect any difference whatsoever. Someone with an oscilloscope and a lot of time MIGHT be able to find something, but I certainly can't. Going the other way... in my case, picking up bluetooth from my cell phone and, through a 3.5mm-to-RCA-jack adapter cable, going to my home theater system's amplifier... again, I can't hear any difference from when I go directly from my phone's 3.5mm jack to the amplier. I cannot detect any lag, I cannot detect any reduction in audio quality. In essence, as far as I'm able to tell, this is every bit as good as any hard-wired connection I could hope for. Yes, it's an additional device, which isn't as convenient as top-quality bluetooth built right in to both devices at both ends of the connection. But it's small and easily carried, and thus the inconvenience is minimal. The only issue I can't really address is whether this will continue to work as well as it has so far, longer-term. Some electronic devices "wear out" over time... poor chip design, poor thermal management, etc... and I can't really comment on the long-term life of the device. But if it continues to work as well, long-term, as it has so far in my limited useage... I can recommend it unconditionally.

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!

Amazon me ha ofrecido este transmisor-receptor bluetooth a cambio de mi experiencia honesta e imparcial. Tributo un porcentaje significativo del valor de los productos que recibo gratis, por lo que soy igual de crítico que cualquier otro cliente. De momento sólo lo he usado como receptor, que es para lo que lo necesito. En la radio del coche (que es del año 2000 y aún va con cassette) tengo conectada una interfaz compatible con radios de Renault que adapta la entrada auxiliar de la radio a jack de 3,5mm macho. Para no estropear el conector jack del teléfono ni tenerlo atado durante el viaje, un adaptador bluetooth como este Syntech me resulta imprescindible. A continuación expongo sus ventajas e inconvenientes. Hablo de smartphone porque es lo que uso con él, pero se puede usar con muchos otros dispositivos. ✅ Mide como la cajita de un anillo. Cabe de sobra en los compartimentos más pequeños del coche ✅ Buena calidad de transmisión de sonido, aunque esto depende más de los altavoces. ✅ Autoapagado automático tras 5 minutos sin usar. Cuando vuelves al coche después de irte de su rango, pulsando el botón de encendido se vuelve a conectar automáticamente al smartphone vinculado. ✅ También se apaga la pantalla tras pocos segundos sin tocar botones, para no gastar más batería de lo necesario. ✅ Me encanta la funda de silicona removible y aparte de proteger, estéticamente le queda muy bien. ✅ Al conectarlo y al conectar al móvil hace un sonido bajito muy sutil. ✅ El volumen que controlan los botones del adaptador es el propio del móvil, aunque estos botones como mencionaré como desventaja no funcionan bien. ✅ El volumen al que estaba el bluetooth del smartphone se queda asociado para tenerlo en el mismo nivel al volver a conectarlo. Esta característica es propia de Android, por lo que sería raro el adaptador bluetooth que no actúe así. ✅ En la configuración de bluetooth del smartphone muestra el porcentaje restante de batería de 10 en 10. Me está gastando menos del 10% por trayecto de ida y vuelta al trabajo (por cada 40 minutos). ✅ Incluye un adaptador jack 3,5 macho a dos hembras para conectar por cable dos móviles a la vez. Supongo que por si se queda sin batería. ✅ El cable es independiente del adaptador, pudiendo reemplazarlo si se estropea. ✅ El tacto de los botones es agradable y su superficie amplia. ❌ Las funciones de subir y bajar volumen no responden o responden con retraso, aunque la pulsación larga funciona bien para avanzar y retroceder la canción. 📜 En resumen, es un dispositivo muy completo y versátil, pero teniendo en cuenta el mal funcionamiento del volumen le daría 4,5 estrellas.
