Oasis Plus 2 – Bluetooth Transmitter for TV with Remote Volume Control, Supports Two Headphones, aptX-Adaptive, Soundbar Passthrough, for Optical or AUX TVs

My use: I connect two bluetooth headphones (wireless) to the TV [LG C1] for casual viewing and two audiophile headphones (wired) for serious viewing (opera, movies). The speakers, while good quality, don't work for my old ears or very well for my odd-shaped room. The TV does a lousy job of connecting to the bluetooth. Fussy sometimes, dropping connections, forcing me to go into the settings to correct too often. The Avantree solves all of this. The Avantree powers on when the TV powers on. The Avantree connects immediately to both bluetooth headphones as soon as they are turned on. The Avantree passes the optical signal through to my dac/headphone amp so the wired headphones turn on instantly when that amp is powered on. Any one or all four headphones all on with a single click. The TV forced a choice: wireless of wired, not both. Now all four headphones work together. Caveat: If you have Bose QC Ultra headphones (as I have) you will notice that both the Bose and the Avantree advertise that they use the aptX-adaptive codec. The lowest latency seems to be aptX-LL which the Avantree supports but the Bose does not. There are other quality bluetooth headphones that will give a slightly better lip-synch for TV by connecting with aptX-LL. The difference is subtle but some people are sensitive to it.

This is one of those rare products which just works the way you want it to. First time, every time. The manual which comes with it very clearly explains how to set it up, simplifying what could be complicated. It informs you to properly configure things which could be otherwise easily be overlooked. Everything connected easily and worked well on the first attempt. Pairing it with a variety of different bluetooth headphones was a snap. It was all so nice. If only all products worked this nicely. In addition to the clear user manual and easy setup, the device has lots of connection options. Yet they've somehow presented it all in an easy to figure out front panel. And it shows you what is going on. No guessing if the device paired in SBC mode or aptx LL. It is clearly shown on the front panel. Want to change the audio input from the aux jack to the optical input? You simply tap the AUX/OPT switch on the front panel. And then it displays which is selected. Again, no guessing. Which do you prefer, aptx LL or aptx HD? Rather than letting the devices decide which to utilize, they provide a simple slide switch appropriately labeled for you to select which connection option to use. And then it shows you on the front panel which they actually connected in. Again, no guessing! Someone really took the time to make what could be very complicated and present it to the user in an easy to use manner. So, so nice! In the future, I will be looking to Avantree for other products. I hope they are all done this well. I am not affiliated with Avantree in any way. I am not a formal Amazon reviewer. Look at some of my other reviews. They range from highly critical to highly complimentary, as in this case. I'm just a regular guy who buys various things from Amazon. This is my honest review.

I purchased his device years ago because I live in an apartment and I generally listen to my music and TV with headphones as not to disturb my neighbors. This transmitter / receiver worked well for five years, but I had to get a new one when it had trouble pairing. Unfortunately while this was the best transmitter/ receiver five years ago, now there are better options, simply because you have to pair your devices blind with this. Because of this I returned the second one I purchased (in 2023). Today, there are just too many Bluetooth devices that will: pair with this device instead of your headphones, or cause interference when you try to pair. So if you live in a house without a lot of Bluetooth devices and you are far from your neighbors, this might work for you. However, there are similarly priced options on Amazon that allow you to select the device you wish to pair. A more detailed review follows. My item came packaged in card box with an outer sleeve displaying the item an brand. Included were the transmitter /receiver, an optical cable, a 1/8” male-male stereo cable, a usb power cable and the instructions. A 120V (wall plug) to USB adaptor was not included. Avantree justifies this as reducing waste and recommends you plug the device directly into you TV. The justification, to reduce waste, while common today is non-sense and ridiculous. Set up is fairly straightforward. The TV audio out connects on the audio in side and your stereo (or what ever device you normally send audio to) connects on the audio out side. I should note that while the device supports both optical audio and a more traditional 1/8” stereo cable, you can’t cross these in bypass mode. i.e., if you use the optical cable for input, the optical cable has to be used for output for bypass to work. Pairing devices to the transmitter can be difficult. When switched to transmitter mode the device automatically will pair with the last device(s) or enter pairing mode. You can also hold the pairing button for a few seconds to enter pairing mode. As mentioned earlier, in either case, the device will latch on to the strongest signal and pair with that. It doesn’t matter if that signal is your headphones or your neighbor’s smart speaker, because pairing is blind. The second “B” channel is even more difficult to pair because wi-if signals interfere on that band. In fact the only way i could get something paired on the B channel was to take the device to my car, drive far away and pair my headphones away from any interference. Once set up the device has three modes, transmitter/ bypass, off/bypass and receiver. In transmitter mode you can both transmit and have music go to your stereo. In the off mode, the device is unpowered but sound will go to your stereo. There are two sound modes, low latency and high fidelity. In the low latency mode, lag is minimized sacrificing some sound quality. In the high definition mode, audio quality is prioritized at the expense of some lag. The former mode requires headphones that can support low latency. Either way sound quality is fine and there is minimal lag. Again, while I was happy with my purchase five years ago, today the technology/ features of this device are outdated. Blind Bluetooth pairing just isn’t a good option today and for that reason alone I can’t give it five stars, even if the blind pairing is part of the design. I’ll rate this for four stars, for the quality of the device sound and low latency. I’m deducting a star primary because of blind pairing and a lack of a usb to wall adaptor to power the device.

He comprado este <Avantree Oasis> para añadir emisión bluetooth a un televisor que no tiene esa característica. Yo ya tenía otro aparato muy similar, el <Avantree Oasis Plus> que me parecía muy satisfactorio pero era más caro (70 euros). Ahora que necesitaba otro, he querido probar primero el Kastewill (40 euros) y luego este Oasis-no-plus (60 euros) por ahorramre algo de dinero. La sorpresa negativa de estos dos aparatos (Kastewill y Oasis-no-plus) ha sido que cuando reciben por cable óptico SPDIF no funcionan los botones de subir o bajar el volumen. Lo he comprobado empíricamente, y luego lo he confirmado leyendo los repectivos manuales. El volumen sí se puede regular si está recibiendo por jack, pero no cuando recibe señal por cable óptico SPDIF. Ese es el motivo de que haya tenido que descartar estas dos opciones más económicas, devolviendo los aparatos; y he vuelto a comprar otro <Avantree Oasis Plus> que es más caro pero sí me permite regular el volumen en la configuración que yo utilizo. Yo pensaba que la única diferencia entre el Oasis y el Oasis-Plus era que en el primero la selección del modo By-pass anulaba el funcionamiento normal (bluetooth) pero luego he encontrado una página de Avantree en la que explica múltiples diferencias entre estos dos modelos. Podéis localizar esa página introduciendo en un buscador las palabras Avantree comparativa Oasis vs Oasis plus. ------------------- Este <Avantree Oasis Plus> me parece excelente y estoy bastante contento. De hecho, meses después he comprado un segundo aparato igual. El primero lo compré porque tengo un televisor LG cuyo emisor bluetoot tiene un alcance muy corto y también porque el televisor no me permite usar simultaneamente los altavoces internos y un altavoz bluetooth. El <Avantree Oasis Plus> solucionó ambos problemas, recibiendo la señal del televisor por cable óptico SPDIF (el televisor LG sí permite emitir audio por los altavoces internos y simultaneamente por cable óptico, pero tienes que usar un altavoz APTX LL de baja latencia para que no se note la demora entre el sonido de los altavoces internos y del bluetooth). Luego he comprado otro televisor LG (de oferta) que no tiene emisor bluetooth y necesitaba un aparato que añadiera esa función. Por ahorrame algo de dinero he probado primero con un Kastewill (40 euros) y luego con el Oasis-no-plus (60 euros) pero he tenido que devolver ambos por un detalle: Cuando reciben por cable óptico SPDIF no funcionan los botones de subir o bajar el volumen. Lo he comprobado empíricamente, y luego lo he confirmado leyendo los repectivos manuales. El volumen sí se puede regular si está recibiendo por jack, pero no cuando recibe señal por cable óptico SPDIF. Finalmente he vuelto a comprar otro <Avantree Oasis Plus> que es más caro pero sí me permite regular el volumen en la configuración que yo utilizo. Yo pensaba que la única diferencia entre el Oasis y el Oasis-Plus era que en el primero la selección del modo By-pass anulaba el funcionamiento normal (bluetooth) pero luego he encontrado una página de Avantree en la que explica múltiples diferencias entre estos dos modelos. Podéis localizar esa página introduciendo en un buscador las palabras Avantree comparativa Oasis vs Oasis plus. Para completar la reseña diré que lo más negativo de estos aparatos Avantree Oasis es la botonera, que no aporta sensibilidad o respuesta háptica: no hay sonido o vibración que indique cuándo estás pulsando el botón, y por tanto puede ocurrir que no sepas si estás pulsando bien o con suficiente fuerza. Salvo ese fallo de la botonera -que tampoco me parece muy importante-, el resto del aparato es muy correcto. Se instala y se maneja bien. El alcance no es el prometido pero es mucho mejor que el de otros emisores bluetoot. Y tiene dos ventajas adicionales que me parecen importantes: una es que permite emitir bluetooth APTX LL de baja latencia, y la otra es que puede emitir al mismo tiempo a dos dispositivos bluetooth. Por todo ello, yo estoy muy contento.

Alles is geweldig, goede kwaliteit, ik beveel het iedereen aan!

Mycket lättinstallerad och lättanvänd, funkerar som den ska

My wife likes to watch TV in bed to get to sleep. Has done since we married 43 years ago. So I had hooked up a wired connection from the RCA jacks on the TV to a FiFo mini amp, to a pillow speaker with a 3.5 cable. As time goes on the connections get old and the pillow speaker stopped working, so it was time to upgrade. I saw from reviews that Avantree was mostly recommended so bought this bluetooth transmitter with the slumber pillow insert, from the same company. Setup was easy, working first time after I found the on button has to be set to Transmit (TX). The slumber pillow works great with this. One issue is that my TV doesn't have a USB port so had to get a cell phone charger to plug in to the wall jack. That worked fine. The But ... I had a thought that it would provide a bluetooth connection to other devices but that doesn't seem to be the case. I can't see a bluetooth device called Avantree from my phone. I had thought I would have been able to connect the audio to my phone via Bluetooth too but that is no. So its not a true bluetooth in that sense. It does work perfectly with the Avantree Slumber. I contacted support regarding not seeing the bluetooth device from my phone. Working as designed in TX mode. Support was excellent to deal with.

Excellent boitier transmetteur et récepteur bluetooth. Tous les câbles sont inclus. Très facile d'utilisation et très efficace. J'adore. Bravo Avantree.
