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

Just a bit difficult to set up with ear pods, but the manual explains things very well. Excellent sound quality.

Nice dual-channel Bluetooth transmitter.Easy to set up.Good range.Low lag, works well with a TV.Compact design.Good value for the money.I would recommend this product.

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.

This review is forAvantree Oasis Plus Certified aptX HD Bluetooth 5.0 Transmitter Receiver for TV, Soundbar PassThrough, Class 1 Long Range, Voice Guide, Touch Screen, aptX Low Latency Audio Adapter for 2 HeadphonesI've had it for going on 4 years now; it's plugged in with a digital optical cable in transmitter mode, so I can use USB headphones/earbuds when watching movies at night. It still works without issue; I keep it in LL (Low Latency) Priority mode.One set of old headphones I use was relegated to TV use because the Oasis Plus has its own volume controls, and the old bluetooth headphones volume switch is almost dead - after fighting to get the headphones to max volume, I can use the Oasis volume controls to quiet them when needed.The voice prompts, when enabled, come out of a speaker on the Oasis Plus itself, which is VERY useful for figuring out what's going on.The 164 foot range is the standard consumer marketing range of "If the transmitter and receiver are both on an empty planet at the top of tall, tall towers with no obstructions between them, the range would be...". Suffice it to say the range is obviously far superior to my previous little Saturn bluetooth transciever, as well as superior to the range of any laptop or cellphone in the house. I attribute at least most of that to it using a real antenna. Range is obviously affected by other Bluetooth devices, other 2.4Ghz devices including 2.4Ghz wifi, walls, people, windows, airducts, appliances, etc. I can still hear it throughout the house (it's pretty centrally located, to be fair).Seeing the SBC/APTX/LL/HD light up is kind of nice; it does seem to operate with decent latency with SBC mode earbuds- if I watch for it, I can see it, but it isn't bad. With APTX mode it's quite low latency. I don't have any APTX LL mode equipment, unfortunately. Essentially: This, in transmitter mode, will have as low a latency as your receivers allow. For me, APTX headphones are good enough when I care, and SBC is good enough when I don't care. If they weren't, APTX LL would have been.Power is by Micro-USB with no internal batteries, which is part of why I bought it - my previous tiny bluetooth transceiver's internal batteries died, rendering it useless. This one just keeps trucking. If you need to take it portable, use a USB power bank.I'm not sure how dual headphones works, since I only use it with one.

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.
