Pairing two Vizio sound bars for one source synchronized music with Avantree oasis plus 2

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!!!

Adjust TV Sound to PCM

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

Works but missing something important

Better have a spare wall wort for usb, because it uses a usb cable for power but doesn’t come with a usb wall wart. That is the only reason I’m giving it four stars instead of five stars. Easy to set up with optical cables. It comes with one but you will need a second to use the bypass/passthru feature. My setup was optical from tv to device, then optical out from device to soundbar. Now my family can listen to the tv at their level and I can pair audio to my headphones or hearing aids.

Highly improves listening to TV!

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!

I really wanted this to work in spite of strength of the bluetooth transmitter is 12 feet!

The bluetooth range is terrible. The specs say 155 feet. I tried this with 2 different bluetooth devices. Both as a single connection each. and then both together.I also tried it with spdif and 3.5mm audio. spdif on my samsung tv and 3.5mm ausio on a lenovo laptop. If I am sitting within 3 feet of it ... it's great. so there are connectivity problems with this Oasis.Debating now to try a replacement, or return for something else. Will update.Update: did the paperwork, next day received new Oasis. Initial test. Don't know why the initial connection to BT earphones selected SBC as the codec and should have selected aptx HD (H). connected them to earbuds flicked the HD LL switch and switched between SBC and H. Now will test w headset again. Now the headset connects in HD!!Will do another test with the optical cable. Then I will shut down the wifi for 15 minutes after I power up the Oasis again. Rasing to 4 stars.Second update: connected to optical from samsung tv and output to soundbar. Everything works flawlessly.CONCLUSION: Obviously the first device was defective. I had mentioned that the box looked as if it had been opened although the seal was intact. This device was a POS. QUESTION?: Why does Amazon or Avantree let this crap happen? This makes me reluctant to buy from Amazon. Ok they will replace it, but do you want to play the game “will this one work”? After a couple of times I hate the game! I have been buying elsewhere and NOT running into this issue.REVISIT: so I tried it today the next day. No sound. The optical connection kept flashing on and off. WTF it worked last night. Today no sound??Will contact support and if no satisfaction then back to Amazon. Back to 1 star.How difficult is the setup with a Samsung tv let me count the ways. First this is old bt tech but still works. The real issue was the optical cable output format. It was set to dolby atmos, BUT needed to be set at PCM. THE Spectrum input worked for audio out but NONE of the apps (netflix, prime, appletv …). So I separated the power so it would stay on when I shut off the tv. A huge PITA. But when it works it’s nothing short of wonderfully!Well the protocol dropping aptxhd at totally unpredictable times is more than annoying. I really want stuff to work. I don’t want to have to jump through hoops to keep it working. This is truly a POS. DO NOT BUY!! I am sending the second one back too. I will NEVER buy a product from Avantree again. For $69 this is way too much of a headache to get working, to keep working and the random drop offs are the straw that breaks my camel’s back.

A good product from Avantree

I am a big fan of Avantree products. The Oasis 2 works well even though I had a minor problem with the first one but Rosally in customer service helped me. I now have another thanks to her and it works well and as expected. Oasis 2 is easy to hook up and operate and well worth the money.
