Avantree Oasis Plus 2 – Bluetooth TV Transmitter with Remote Volume Control

Samsung 58 inch TV with optical audo. Two Cowin E7 headphones. Connected right in series on the optical. If you turn it off, it goes right through to the speaker bar. It was easy to pair the headphones and it is very good sound quality. Turn on the box, turn on the headphones, it all hooks up. Very nice.

I have a unique set up for entertaining outside that consists of a covered area (Porte cochere) and a large back patio in which I wanted to play music. I already had a vizio 5.1.2 SE elevate soundbar and subwoofer in the covered area and in order to enjoy the music on the patio, I had to turn the volume up so loud in was uncomfortable in the covered area. So my solution was to just get another Vizio sound bar for the patio. But then I thought the sources would be battling and in between two settings you would be able to hear different music playing which is not desirable. So I asked chat gpt if I could pair on source to two different devices. The immediate answer was no only one device can be paired to another device. But then chat GPT explained however, the Avantree Oasis Plus 2 device can receive an input from a source and then it can pair to two devices. It appears this device is mostly used so two people can listen to the same music on ear phones. And it said I could pair the two Vizio Sound Bars to one source. So I bought the Avantree Oasis Plus 2 from Amazon and with Chat GPT helping me trouble shoot, I quickly paired both soundbars! OMG I am going to break my arm patting myself on the back! This device synchronized my sound bars perfectly! The multidirectional sound bars sound better than I ever expected. The Best Buy geeks gave me a funny look and rolled their eyes at me when they realized I was not going to their Soros solution at multiples of the cost of two sound bars and the Avantree device. My solutions blows away the soros system. Especially with perfectly synchronized subwoofers above in the garage attic. Extremely happy with this device and this solution!! Plus my one tv remote controls both soundbars bars so I can enjoy different volume levels in each area!!!

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. EDIT: Device failed in three months; failure to pair with two headsets and failure to reset to factory settings. Avantree is responsive for problems and did replace the item. New one is working fine. But ...my assessment of the situation for 2026 and beyond is that this item and similar ones are obsolete. For future use do not buy old bluetooth devices for TV viewing. Newer Auracast devices (when the technology is mature and stable) will solve latency problems, connectivity problems and allow far more than two headsets to be reliably used. Avantree is one of the leaders in Auracast devices but I expect serious competition mighty shake that in the future. Also future TVs will support Auracast instead of bluetooth and transmitters like this will not be produced.

I was hopeful since this was the 2025 model that perhaps this Avantree product would connect with my B&W Zeppelin Pro wireless bluetooth speaker. It appears that the hardware for pairing is similar with the rapid blinking and pressing headphones button method, but it did not pair successfully. So unfortunately, it is a return. In the meantime, I tried also pairing with WF1000-XM4 and XM5 with the device in Transmitter functionality (I did not test receiver functionality). And they both paired successfully and sounded OK. One thing to note was that the XM5's support APT-X Codec, but I was not able to change the codec to AptX to support higher quality sound... The device is easy to set up, assuming that pairing works OK. In my opinion, there are a lot less expensive dongles that support the basic SBC if SBC is the only thing you are looking to use or that is supported by the device. Maybe for other devices the AptX works ok and connects ok, but I seemed to have trouble with the devices I wanted to use it with.

Works great with my Insigna (low budget) camping Tv. I pair it to my headset using optical plug. Remember to turn off all other Bluetooth devices when you are pairing your devices. Can't wait to try this out on hotel and cruise tvs while on vacation.

Very seldom does it connect to my Apple Ear Pods when I take them out of the case. I continually have to turn the device off then on to connect. OK once connected, however, it could be the Apple Ear Pods rather than the device. Let me describe why. Had to use this device because I found out from Perplexity AI that LG Smart TV's don't support Apple Ear Pods. I also found that Apple Ear Pods use a different proprietary system and are not like all other Ear Pods so they have a tendency to have issues with some devices. If anyone else has this issue with Apple Ear Pods connecting to an LG Smart TV this device will work. Other than the connection issue the volume remote is kind of funky but works.

Works well, good value

I was unable to connect my Avantree Oasis Plus 2 device to my TV and headphones. I watched the Avantree installation guide on YouTube 3 without success. I contacted Support and was connected to Riza. Being somewhat inept technically, I could not follow her chat instructions properly. She called me, and with five minutes I was able to listen to a program via my headphones at one volume level, and the TV played with a different volume level. Riza was extremely patient with me and provided very clear instructions that I could easily follow. Great product and even greater support.

Świetnie łączy się z moimi apartami słuchowymi Phonak. Ale pilot do zwiększania głośności nie działa o nie może za to poglasniam na słuchawkach. Zasięg duży ponad 10m. Świetny zakup.

Very good!

Ho scoperto, a mie spese, che non è possibile collegare due cuffie bluetooth al televisore, così mi sono messo alla ricerca di un dispositivo esterno che mi permettesse di collegare le due cuffie alla tv. Così mi sono messo alla ricerca su Amazon per vedere se era possibile trovare un dispositivo adatto alle mie esigenze ed ho trovato un ottimo trasmettitore! Si tratta di “Avantree Oasis Plus 2”, un dispositivo che si collega alla te attraverso l’uscita ottica del televisore. L’ho montato e in brevissimo tempo ho fatto il riconoscimento delle due cuffie e funziona benissimo. Ho risolto il mio problema con un piccolo dispositivo geniale di cui sono estremamente soddisfatto

Vlotte installatie en stabiele verbinding. Heb ik gebruikt om een platenspeler te verbinden met een BT luidspreker
