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 Black

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.

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

works well, battery lasts a full day for me, using to pair IEM's with my phone. There is a little noise in the amp when no audio is playing however leaves when audio starts playing. Sound is lound and clear with very low latency (for a Bluetooth connection). Device was easy to pair and works at a decent range.

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.

Je n'avais pas vu que ce type d'article était sorti ! Quand je prenais l'avion, j'avais le choix entre mon casque à réduction de bruit encombrant et les écouteurs de très mauvaises qualité fournis par les compagnies, et dont l'usage unique m'a toujours paru invraisemblable. Ce adaptateur fonctionne à merveille avec mes Airpods 4, qui suppriment environ 80% des bruits environnants sans être des écouteurs internes dont les embouts silicone me dérangent. L'autonomie est parfaite, un produit très utile pour ceux qui prennent des longs courriers, ou qui veulent tout simplement brancher leur casque sur un mini-jack.

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
