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.

Works flawlessly, very very easy to setup. Plugging all cables in, and pairing two headsets took less time than unboxing all the items. Compared to a different brand that I won't mention, this works flawlessly. The competitor brand I used, started malfunctioning within a week. I'm happy that there's also a remote to control volume when I'm using the optical connection.

I paired with with a Vizio S3851w-D4 and my AT-LP60X. Sounds great and works once I got it paired. The pairing was a hassle. For what ever reason it would not make the initial pairing from the spot my record player sits in my room, so after clicking the buttons a bunch and nothing new happening, plugged in the Oasis in right next to the sound bar and it paired almost immediately. This is strange because the record player is about 20 feet at the most from the speakers. I then brought the Oasis back over to the record player and plugged it in and now it re-pairs without any issues and it streams the audio perfectly. That's really odd. I'm super happy with the product overall, as this lets me move the AT-LP60X to a much more convenient location. So if your having issues pairing, move the Oasis right next to the device and then it will most likely work to pair perfectly fine afterwards.

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.

Worked as advertised. Easy setup and operations.

My husband and I like to listen to opera videos at concert-hall volumes. Since we live in a condominium, this is not possible with speakers, and we must use headphones. This is the first Bluetooth Transmitter we have found that will drive two headphones simultaneously, allowing us to listen together. The voice/audio synchronization is perfect, using Bose QuietComfort Ultra headphones.

Very nice Blue-tooth transmitter. Very well built, super easy pairing, no hassles at all. BUT!!! Lip sync was horrible. I have a Cowin E7 headphones about 6 years old so they are analog. About a 6 year old Phillips Smart TV. You need digital headphones and a newer TV. Best choice is to get a TV that support super low Latency and bypass the transmitter.

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. The sound quality on the replaced item is not as good. 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.

Excellent unit that has made my LG C3 OLED TV useable with headphones! Audio is rock solid and plenty loud enough even without the boost option. In fact the boost introduced a bit of distortion at higher volumes, but luckily I don't need it. The remote for the volume is very responsive and I'm very happy with the unit. It's a very clean, pleasant sound with no noise or buzzing. The only slight niggle is that if I pause any streaming service (Prime, YouTube etc.) the audio does start to break up and go out of sync when I resume the programme. This doesn't happen when using Blu-ray or TV recorder playback - it only seems to be when streaming either from the TV's built in apps or via 4K Firestick. A quick power cycle of the unit always restores the audio perfectly though. (I might plug a USB power adapter into smart socket so I can just ask Alexa to power reset it 😊) It's currently getting its' power from one of the TVs USB sockets. I have tested compatibility with: Shokz Open Dots One Soundcore AeroFit2 Sony WF510 Tozo Openbuds Soundcore Sport X10 Cambridge Melomania 1 All were bought over time to try and get a set of headphones working natively with the LG OLED - none worked reliably with it! All the above headphones worked with other devices and now work seamlessly with the Aventree Oasis Plus 2. Highly recommended!

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
