2-in1 Transmitter & Receiver
Enjoy the flexibility of where and how you want with the Oasis B’s ability to both transmit and receive audio. Essentially what this means is that when in transmitting mode, the Oasis B grants Bluetooth capabilities to the sound source (i.e. your TV). When in receiving mode, the Oasis B “gives” Bluetooth to the sound recipient / listening device (i.e. an old boombox).
No Audio Delay
Worried about a wireless connection creating sound delay? Worry no more. As long as you use Bluetooth headphones / speakers that support aptX Low Latency or FastStream, you‘ll get perfectly synced audio with the Oasis B. Enjoy the same no-delay audio experience of a wired connection… but without the tangled mess.
Pass-Through Feature
Not everyone wants to listen through headphones, and that’s perfectly okay. With the Oasis B’s audio pass-through feature, you can listen through your own headphones at your own volume, while others around you can simultaneously listen through a soundbar or stereo AVR.
User-Friendly Interface
We believe that technology should make your life easier, not more difficult, and we designed the Oasis B’s interface with that in mind. With independent pairing buttons for up to 2 different audio devices and with volume control built into the transmitter, you should have no problem pairing and adjusting your devices.
Dual Link Capabilities
As the old saying goes, “Sharing is caring.” Share the love by pairing up to two different headphones to your Oasis B and enjoying your listening experience together. Everything’s better when you share it with a friend, so grab a couple pairs of headphones, get cozy, and settle in for a nice, shared movie night.
Extra-Long Range
What’s the point of wireless if it only works within the same range as a wired connection? The Oasis B
comfortably manages a range of 165 feet / 50 meters, giving you the freedom to stretch your legs, answer the door, work on chores, or do whatever your heart desires – all while retaining a stable and reliable Bluetooth connection.

My wife and I got Bose headphones for Christmas and our tv being 5-7 years old it was not able to connect to 2 sets of headphones at the same time. This unit was a little tricky to hook up, mainly because we had 3 variables, the tv, the headphones and the Bluetooth unit. Once connected it was awsome for my 74 year old ears. Fantastic product!

Initially couldn’t get to work but believe the optical cable bad since got nothing on 2 different TVs of differ brands. Switched to RCA cable and works great. Husband has hearing problems and wanted to use his Bluetooth headphones to listen. Also have used with Bluetooth speaker placed near his chair and that works well also. Can use with 2 headphones/speakers. I can also listen to TV speakers while he uses headphones. Super easy to set up - just plugged in, made one adjustment to TV audio and done. Did not have to turn off TV speakers but will mute if using Bluetooth speaker.

I bought the Avantree Oasis B to work with my Samsung TV, Vizio Soundbar, and Phonak hearing aids.Phonak sells a similar product for $200.I’m using the TV’s Opical output to feed the soundbar and from the product description I thought the bypass function would allow me to use both optical outputs and Bluetooth. But this is not the case. When using Bluetooth the optical output is disconnected.I fixed this by using a 1:2 optical splitter to feed both my soundbar and the Avantree Oasis B which is powered by a USB port on the TV. Now each time the TV is turned ON the Avantree connects to my hearing aids so I can listen to the TV and others in the room can hear the TV’s soundbar.

I received my Avantree Oasis B Bluetooth 5.0 Transmitter: Gray, BTTC-500-W-EU yesterday 11/21/21 and it didn't take me long to hook it up as the instructions were very easy to understand. I already had an optical cable from the TV to my Sound Bar. So I disconnected the cable from the sound bar and connected it to optical input on the transmitter. Then used the optical cable that came with the transmitter and connected it from optical output to my sound bar. After a try or two, I was able to sync my Apple Air Pods to the transmitter and wow, the audio quality was just perfect. I also like having volume controls to adjust the volume to my Air Pods. My only complaint is the Bypass function. I wanted to be able to listen to the TV using my Air Pods and have sound coming from the sound bar at the same time. But when switching the transmitter to Bypass, audio comes out of the sound bar, but it cuts off the Bluetooth signal to my Air Pods. Since I was already using an IR transmitter & headphones which was connected by using RCA cables from the TV to 3.5mm mini plug to IR transmitter, I disconnected the mini plug from the back of the IR transmitter and connected it to the AUX port on the sound bar. Now I can listen to the TV using the Bluetooth transmitter and others can hear the audio thru the sound bar without having to use the Bypass feature! The other thing I like about this Bluetooth transmitter is when I connected the USB power cable to the USB port on the TV, when I turn off my TV, the Bluetooth transmitter turns off as well. and of course, when I turn on the TV, the Bluetooth transmitter turns on and automatically connects to my Air Pods! Since I just received the Bluetooth transmitter yesterday, I haven't really used it over a period of time, but so far I'm glad I finally decided to spend a little more money and purchase a better quality Bluetooth transmitter as the $9.99 devices never work as expected. I also ordered Bluetooth headphones which should arrive soon. Do yourself a favor, spend a few more dollars and get this Avantree Bluetooth transmitter... you will be glad you did!

Update 2: RETURNING this. It has become impossible for me to connect my headphones / earphones to the device. When turned on it shows that it is already connected to two devices. This happens every time turn it on.UPDATE 1: Whenever I connect 2 sets of earphones, the sound quality deteriorates tremendously. The sound is intermittent with random cuts and popping noises. Both my earphones have the QCC3040 chip and support the latest aptx codec. When connected to one of the headphones the transmitter also shows that aptx is being used (not aptx-ll). This is probably because it didn't have the latest aptx adaptive. I am using the optical cable to connect with my TV and a 5 V-900 mA power source. The sound quality is fine when only one headphone is connected.Using this device in transmitter mode with Bluetooth headphone. The headphones works great. I am not sure if it can take advantage of of the aptx adaptive codex though.I couldn't find input voltage specifications on the box, so I am using my TV's USB for power (5V 900 mAmp). Seems to work.

I was concerned it may not connect with my Onn wifi/bluetooth speaker (my Micus rx/tx would not pair) but it paired quickly without issue

I had hoped getting a better range with this unit because it's class 1 and read good things from other sources. Seemed equal to another unit I tested in an environment with lot's of obstacles. Found a dual antenna unit more flexible because I could adjust the two antennas at different angles which seemed to give me better results. One thing to mention. when this unit exceeded the range limit it made weird noises and my BT speaker would turn off. With the other unit, my BT speaker would simply stop and reconnect once back in range. Sound quality seemed good and came with cables. Either unit is a cool way to have two speakers to a single source without using an additional app like JBL or TWS (True Wireless Stereo). Compare with MUSICOZY Bluetooth transmitter receiver.

Like its" compactness , no charging" is a big plus and it delivers the sound. I listen a concert that night and was not disappointed. Can hardly wait for NASCAR . For anyone with a paired/no sound, explore tv settings as I did. Cause up till then I's worried......

I had a simple requirement, I wanted to be able to listen to the music that was playing on my PC at all locations in my home. My blue tooth earbuds would only reach about 30 ft from my PC and then they would cut out. With this device I can now hear my music anywhere in the house including the basement. That's 2 floors distance from the transmitter. Setup was easy (the only problem was realizing that the volume was set very low so I thought that the range extender was not working, once I increased the volume on the PC all was well). Also, support options from the seller, if you should require it, are excellent. I am very happy with my purchase. Highly recommended.

I bought the device because I have a pair of very comfortable noise cancelling headphones and when I watch TV late nights I don't want to keep the rest of the family awake. I simply hooked up the unit and connected the headphones. I had to reset the headphones in order to connect, but it works nicely. No problem.

Me salio muy bueno, funciona a la perfección, me demore un poco haciendo la conexión, pero una vez quedo hecha funciona bastante rápido y el sonido perfecto y sin retrasos.
