- Avantree Audikast 3 – Bluetooth 5.3 Transmitter for TV Audio via Optical & AUX Outputs Only, aptX Adaptive, Dual Headphone Connection, 100ft Range – Not for HDMI–Only TVs

This is a great little Bluetooth transmitter!! It has low latency, handles two Bluetooth devices at once, and has a handy volume boost control. Sound quality is superb. When powered via USB from my TV, it turns on with the TV, in the pairing mode! Pairing my headphones is a snap! Works every time within seconds. I highly recommend this product. All of this is true for me. It pairs with my headphones in seconds! Much easier to use than the built in Bluetooth on my LG TV!

This unit will work with a set of Bose Bluetooth headphones. They work perfectly, in fact! I originally bought this unit very concerned that it would not work with my mother’s Bose Quiet Comfort 35 II. Unfortunately, she doesn’t have Bluetooth on her television. The headphones worked great on a fire cube, but I decided to go back to cable. I wasn’t sure if this would also work with my TIVO box, but because the television is wall-mounted, I thought it would be easier, as it was obvious, I would have an easier time plugging up the wires. I noticed that my TIVO box has two USB out ports, so I plugged the included USB power cord right into one of these, and the unit powered up perfectly. I then plugged up the optical cable into the back of the TIVO box as well. Because I was using an HDMI cable for both picture and sound, I didn’t need to use the TIVO optical port, it was just not being used. It was a perfect opportunity to use the included optical cable, that came with the unit. I was so pleased because all this meant that now I did not have to go behind the TV at all. The first thing that I did was to hold down the power button on my mother’s Bose headphones, in order to clear all previous pairings. I wanted to make sure there were no conflicts, besides I was only going to use these headphones with this device. Now everything was going perfectly, except for the paring of the Bose headphones. Others have complained that Bose headphones will not pear at all with this device, however, patience is the key here. I too had some difficulty and was convinced that the Bose headphones would not properly pair with the device. I was only more patient because I was used to paring the Bose headphones with my mother’s Amazon Fire Cube. It used to give me trouble when attempting to pair the Cube and the Bose headphones together. Sometimes, I would have to try several times to get them to work together. I had to wait and wait for them to finally connect. Sometimes I started over and even restarted the Cube box again to make them both work together. However, my efforts always paid off, for once they pared, they worked wonderfully. This experience taught me to be patient, and to not be too impatient when trying to pare my Bose headphones to this Avantree unit. It took a long time, and I almost gave up, when suddenly my Bose headphones informed me that a connection had been made. I was so very pleased. Now I know I can use the unit on my television as well as my TIVO BOLT. Perfect, not only that, but I can also watch TV while my 93-year-old mother continues to listen to her headphones. Because the television is connected to the TIVO BOX with an HDMI cable, the sound is being sent to both the headphones through the optical cable, and the television speakers through the HDMI cable. So, if my mom wants to watch television alone, all she has to do is turn down the volume on her television and listen quietly on her BOSE headphones with the Avantree unit. If I come into the room and want to watch Television with her, all she has to do is turn up the regular volume on her Television, so I can listen too. This was so easy to install, I was very surprised at how easy it was to get it going, all I needed was a little patience. Our house is once again quiet, for this is a great little unit. In conclusion, this unit will work with Bose Bluetooth, just be patient. This will work with TIVO, but I only mentioned TIVO in case you also have a TIVO box as I do. This is an advantage, but you don’t need a TIVO box at all to make this work, I am sure it will work perfectly on your television at home.

Item was smaller than I expected. Was very easy to set up using the intructions (e-manual). Works very well and no issues with lag. Sound quality was good (for bluetooth). Tested with a pair of Sennheiser Momentum 4 headphones. Note that sound quality will also dependent other factors like the music source , bluetooth version and codec supported by your headphones. The reason for 4 stars and not 5 is that the Bluetooth signal appears to interfere quite badly with the 2.4Ghz wifi band. My TV kept dropping its wifi connection and connection speed also suffered. This may not be an issue if your tv's wifi supports higher frequencies (e.g. 5Ghz) I placed it a bit further from the tv, but the supplied optical cable is a bit short. If you encounter similar issues, may be worth considering getting a longer optical cable to have the unit further from the tv. I also turn the device off when I'm not using it.

It does just what I needed it to do...or so I thought. Turns out I'm an idiot and haven't paired headphones in so long I forgot how to so I thought my Samsung TV would only paid to Samsung headphones. So I bought this lol. Turns out I don't actually need it but instead of returning it amd getting my $50 back I'm keeping it and I'll tell you why. First of all pairing headphones to it is extremely easy. It supports two pairs at once just like my tv does so that's cool. But the real reason I'm keeping it is twofold. Number one it supports more codes than my tv does. I tested it using my Sony XM3 using SBC, aptX, and LL. Second reason I'm keeping it, which is by far the biggest reason, is it most definitely boosts volume over what I'd normally get from the optical connection. I just use the buttons on the headphones to control the volume. It's a beautiful thing and to me is most definitely worth the money. I have mine hooked up to a remote control power outlet so I can turn it on only when I want it on instead of using the tv usb that would power it all the time. I just switch my tv to optical, turn on the remote control power switch to turn this unit on, turn on my headphones and it just connects. I have 5 different pairs of Bluetooth headphones and so far I've hooked up the 2 I really wanted which is the Sony XM3's and Skullcandy Crusher Evo's and man the Evo's sound the best and get the loudest even over my Sony's. Pairing the Samsung Buds Pro2 and 3 is a bit more difficult bc the TV grabs that Bluetooth signal over everything else so I have to pair to this unit with another device and keeping the tv off so it won't steal the Bluetooth connection. Man if it makes those 2 ear buds louder like it does these 2 that will be CRAZY bc they already sound so good. I'll do that when I get around to it. For now this little Bluetooth transmitter is awesome. It's literally the only one I could find that boosts the volume using the optical input unless I was looking to spend far over $100. This things so great I even bought the 3 year extended warranty for $7 which i mever do but just in case lol. I usually buy 2 or 3 of things I really like but not on a $50 device w an extended warranty lol. It sounds really good to my ears and I haven't experienced even the slightest bit of audio lag. The sync seems to be right on time and I'm using the SBC codec at the moment. Aptx is even better! Sweet little box I really like it!

Ho atteso qualche settimana, prima di scrivere questa recensione, perché desideravo testare per benino il prodotto in oggetto. Quindi passiamo alle mie valutazioni e impressioni. Partiamo con Il dire che il trasmettitore è molto compatto pertanto poco ingombrante. E' fornito con vari tipi di cavi audio oltre che di un cavo usb che serve, tra l'altro, anche per alimentarlo. Ha un tasto per l'accensione e lo spegnimento quando non in uso. Per configurarlo ho seguito pedissequamente quanto riportato nel manuale di configurazione allegato. Come da loro suggerito, ho collegato l'apparecchio al mio tv Sony tramite cavo ottico. Una volta impostato il sottomenù "suono" del mio tv come da manuale, il dispositivo risultava perfettamente configurato e pronto per l'accoppiamento con le cuffie bluetooth. Le cuffie da me utilizzate con questo apparecchio, sono una coppia di Sound Blaster JAM V2 (sempre acquistate su Amazon) dotate di Bluetooth 5.0 e di codec audio avanzati, aptX™ HD e aptX™ Low Latency. Anche in questo caso (seguendo la manualistica a corredo del trasmettitore e delle cuffie) l’operazione di riconoscimento e di accoppiamento delle due cuffie con il trasmettitore è stato abbastanza semplice. Una delle caratteristiche di queste cuffie, oltre ad aver la già citata gestione del codec Low Latency (fondamentale per seguire l’audio con il TV) è la possibilità di regolare direttamente l’audio in cuffia facendo diventare superfluo l’uso del telecomando del TV. Tornando al trasmettitore, posso affermare che le cuffie, una volta accoppiate, restano memorizzate con i rispettivi canali anche se dovessimo spegne sia il trasmettitore che le cuffie. Il trasmettitore inoltre, alla successiva accensione si imposterà automaticamente sempre sul canale LL (Low Latency). Per quanto riguarda la latenza, con le mie cuffie Sound Blaster JAM V2, non ho notato nessun ritardo nel labiale ne alcun tipo ti interferenza tra le cuffie e il trasmettitore segno questo, che il sistema così configurato lavora davvero alla grande. Ultima nota l’audio e buono ovviamente, non aspettatevi effetti Dolby Atmos, Digital o similari. Il sistema non è nato per questo. Per concludere, posso affermare di essere estremamente soddisfatto di questo apparecchio perché soddisfa molte delle mie necessità come dimensioni ridotte, utilizzo di entrambi i canali audio in simultanea, assenza di ritardo e/o interferenza con le cuffie ed infine, la possibilità di tenerlo spento quando non in uso. Cosa dire di più se non ottimo acquisto da consigliare.

llevo 1 mes con el dispositivo, y muy contento. FINALMENTE SE PUEDEN CONECTAR 2 AURICOLARES A LA VEZ, UNA ALEGRIA ! Se instalò en un momento, y de momento no ha dado ningun tipo de fallo. Es mas, es la primera vez que los cascos tienen un alcanze mas lejos de siempre... PERFECTO

Funkar utmärkt men rekommenderar att läsa och söka info gällande vad eller vilken modell som sändaren skall användas till. Topp

Bei einem vergleichbaren, etwas günstigeren, ebenfalls namhaften Kokurrenzprodukt gab es mit meinen Kopfhörern alle paar Minuten Verbindungsabbrüche. Ein Firmeware-Upgrade wurde dort nicht angeboten. Anders hier. Eine mittels QR-Code am Produkt erreichbare, sehr gute Online-Anleitung (auch als PDF erhältlich) führte sehr einfach u. a. in deutscher Sprache Schrtt für Schritt durch die Inbetriebnahme und gab gleich zu Beginn den dringenden Hinweis auf die sinnvolle und unkomplizierte Installation (Windows + MacOS) eines möglichen Fimeware-Upgrades. Nach dessen Installation funktionierte alles wunderbar. Problemloses Pairing und keine Verbindungsabbrüche über Stunden bis zur Erschöpfung der Akkus in den Kopfhörern. So soll es sein. Die Kabel sind gut brauchbar - solider als beim Konkurrenzprodukt. Achtung: Das Gerät hat keinen Akku, benötigt also eine USB-Buchse zur Stromversorgung. Ich hatte das vorher gewusst und mich bewusst dafür entschieden, weil ich Wegwerfprodukte mit fest verbautem (nicht austauschbarem) Akku verabscheue. (Die Akkus in Handy und Kopfhörern von Fairphone kann ich nachkaufen und selbst austauschen.) Ladebuchsen sollte es in jedem Haushalt ausreichend geben, und bei Bedarf tut es auch eine Powerbank. ;-)

Amazing! Connected to my Bluetooth speaker automatically. The sound is great.
