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!

Easy setup. I bought this for the following reasons. Bought a pair of echo dot pair for my TV and to integrate this two speakers, I bought this bluetooth transmitter. Tested it. Works great. the power supply for the transmitter can come directly from the USB port in the TV and it acts as wireless speakers without Alexa (whose sound quality is tremendous) and making this whole thing value for money!

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!

Works GREAT when it works. Set up & initial pairing was a breeze. I was getting rid of satellite & their box allowed 2 headsets to be paired. TV only allowed one which meant the streaming service only allowed one. This could have been the ideal solution and it does work, just not as well as I'd hoped. Wife & I have two different brand/type headsets and each of us have a couple of each (one of ours invariably dies half way through a program we're watching). One of my headsets works immediately when I turn it on other one has to be manually "found" by this box probably 80% of the time. Same with hers. OK, I can deal with that. Not ideal but I can deal with it. The real problem is that somehow in the box often when she turns her headset on, it kills the sound from mine. AND here headset says it is paired but she has no sound. There follows a round or two of turning everything off (including the box) turning things back on and maybe it will work and maybe not. Try again. Stand on my head & rub my belly counterclockwise sometimes helps (just kidding but sometimes it feels like that might be the only thing I haven't tried). I connected via the optical cable & the "no latency" seems to be true. I gave it three stars because of the hassle & not knowing if it is going to work and what it will take to get it going if it doesn't. And maybe if I could, I'd give it 3 1/2 as it allowed me to ditch the satellite.

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.

Ejecuta el servicio que esperaba.Fácil de instalar y manejar. Establece contacto Bluetooth con auriculares universales enseguida sin problemas.

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.
