AvantreeOasis Plus 2 - Bluetooth 5.3 Transmitter for TV to Wireless Headphones/Speaker, Compatible with Optical & AUX Output TVs, with Remote Volume Control, aptX-Adaptive, Soundbar Passthrough

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!!!

EZ to set up, works great" pairs up quick, use channel 1 on the sender, no need for the remote, headset adjusts the sound. Smart TV's require an adjustment to the sound settings, " PCM" on, "Dolby" off

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.

The transmitter does exactly what we wanted it to do! You can set up your Bluetooth ear buds or Bluetooth headphones, or both, and still hear sound from your TV speaker or wireless speaker system. All can be set at different volumes. My husband has difficulty hearing and this is wonderful for him! I highly recommend this transmitter!
