About this item
- [Perfectly Synced Visual-Audio] The Avantree Oasis Plus is aptX Low Latency certified. When (and ONLY WHEN) used with a Bluetooth headphone/speaker that also supports aptX Low Latency or FastStream, it will deliver the ultimate “no lip sync delay” experience, ensuring perfectly synced visual and audio no matter what you watch.
- [Works Alongside your Speaker] The “Pass-Through” or “Bypass” feature of Oasis Plus guarantees simultaneous audio output through the headphones (that are connected to Oasis Plus) AND your external TV speaker such as Sound Bar or Stereo AVR, so other household members can still hear the TV while you’re using the headphones.
- [Two Headphones, Together] The Oasis Plus features a “dual-link” function that allows two Bluetooth headphones/speakers to be connected at the same time; audio will play through both devices simultaneously. Enjoy a late-night Netflix session with a partner, at your own volumes, without awaking others in your household.
- [Wide Compatibility] The Oasis Plus in Transmitter (TX) mode works with any TV that has an audio output port, and it can be paired with any headphone/speaker that’s Bluetooth enabled. In Receiver (RX) mode, it can receive wireless audio signals from your iPhone, iPad or Android via Bluetooth and stream audio into any wired speaker system.
- [Class 1 Long Range Bluetooth] Equipped with the highest Bluetooth range, Class 1 and the running Bluetooth version 5.0 ensures the Oasis Plus provides stable & reliable connectivity up to 164 ft (50 m). Need to start making dinner? No problem, do what you need to do without worrying about the audio cutting out.

Product Description
|
|
|
---|---|---|
Bluetooth Transmitter Use as a Bluetooth TRANSMITTER to Bluetooth-enable your TV, AV Receiver, Radio and other home audio devices to stream music to your Bluetooth headphones or speakers. |
Bluetooth Receiver Use as a Bluetooth RECEIVER, to Bluetooth-enable your home stereo or AV Receiver to receive wirelessly streamed music from your cellphone or PC. |
Bypass Mode If you have only ONE OPTICAL Output from TV, and it is currently used by your AV receiver or soundbar, you need to use the BYPASS function. What’s more, your family can enjoy TV via Bluetooth headphones and a wired speaker simultaneously with independent volume control. |
Supports aptX HD both as a Transmitter or Receiver
Using aptX-HD wirelessly stream for a ‘better-than-CD’ listening experience. NOTE: Slide HD / LL Priority switch to HD side. Works with any aptX-HD Bluetooth headphones (e.g. Avantree Alto Clair ) or cell phones, to stream audio in high definition, allowing you to pick up on all the details and nuances in your favorite music.
Supports Dual-link No Lip-sync Delay
Simultaneously stream audio to 2 headphones or speakers with no delay while watching TV, movies or gaming. Note: To achieve low latency (<40ms delay ) receiving device (headphones / speaker) must also support aptx Low Latency or you may experience a 70-220ms delay. You can check your device compatibility on the aptX official website.
Long Range
164FT LONG RANGE: Utilizing Class 1 Bluetooth technology and an optimized antenna design, the Avantree Oasis Plus can achieve a range of up to 164’ in open air line-of-sight conditions and up to 50-70’ indoors.
NOTE: Operation range can be affected by physical obstructions (walls, people, etc.), wireless interference (Wi-Fi routers, Wireless TV adapters etc.) and also depends on receiving device (e.g. TWS earbuds and compact devices with short internal antennae may only achieve a limited range).
Voice Prompt & LED Status Indicators
It includes full-function (pairing, connected, etc.) voice prompts, status / codec LED indicators, making it remarkably easy to use.
Q: How to turn off / on the voice prompt guide?Hold the second talk button for 7 seconds to turn on / off voice prompts.
Wired & Bluetooth Simultaneous Support
The “bypass” function allows the user to place & connect the Oasis Plus in between the TV and the Soundbar (or Sound system) to achieve the following results:
- Share the same optical / audio output port on TV while being able to get audio through both devices simultaneously. This allows the headphone user to listen at a different volume level; a perfect solution for family use.
- The user may switch between headphones, speakers, or both without having to physically disconnect and reconnect anything. All he / she has to do is turn the headphones or the soundbar on / off.
- NOTE: Bypass can only work with the same type of input / output i.e. AUX input to AUX output or OPT input to OPT output.
Frequently Asked Questions
Q1 Why didn’t I pair and connect it to my devices?
- Ensure that your Bluetooth headphone / speaker is in Bluetooth Pairing Mode. Typically, the LED will either flash quickly or two colors of LED will flash alternately. Please see your headphone / speaker’s user manual for more details. Reset both transmitter and headphone is a good solution.
Q2 Why my headphone is no sound after connected.
- Is the “A” indicator on the transmitter SOLID? If yes, it is connected and ready to use. If there’s still no sound, please adjust the TV audio output settings as user manual suggested or contact your TV manufacturer for support.
Q3: My TV is fixed on the wall, it is difficult to set up cable. Will this play audio coming from my TV box that is connected to my TV via hdmi?
- Yes. This transmitter doesn’t support HDMI jack. But you can purchase an additional Avantree HDMI audio extractor HAX03 to solve it.

Plug and play, easy to pair. Zero latency (voices match mouths) when paired with my Bose QC II earbuds. I can walk all over the house and hear the TV. Great for when I'm cooking or doing dishes. NOTE: MAKE SURE YOU PAIR WITH aptX LOW LATENCY EARBUDS/HEADPHONES/SPEAKERS OR THERE WILL BE A DELAY WITH THE TV IMAGE.
SETUP - I initially used the included optical cable straight from the TV to the transmitter because I figured it would be the best sound quality. It worked great, but I could only adjust the volume with the buttons on the device itself, as opposed to the TV remote. So I switched to the 3.5mm audio cable - also included - and the sound is just as good, and I can now adjust the volume using my TV remote!
Great device, does exactly what it says, and even looks nice. I like the touch screen buttons elegantly laid out on top of the device.

Watch TV both with headset and existing sound bar simultaneously.
My Setup:
Avantree aptX HD Transmitter/Receiver (device being reviewed)
Avantree [2020 New] aptX-HD 24 Bit Hi-Fi Bluetooth 5.0 Active Noise Cancelling Headphones
Existing Vizio TV with optical audio output
Existing Vizio sound bar w/ Bluetooth subwoofer
Setup: Fairly simple to connect the Avantree Tx/Rx to the optical audio output of the TV and, using the Tx/ Bypass mode (switch on the right side of unit), connect the sound bar to the Avantree Tx/Rx. Selected Low Latency priority mode using the switch on the left side. Power provided by USB connection from the TV. Easy on. Simple to pair with both headsets, (Holding Tx button for 2 sec puts the unit in pairing mode, then put the desired headset in pairing mode and Voila!) - voice prompt confirms connection (and the voice can be turned off/on as it could become annoying after awhile but is useful inn the early setup phase.) Device remembers and recognizes each headset as it is turned on and within range. For my situation, the range seems quite adequate. Can roam around the entire house without dropping. Avantree Tx is centrally located in the living room. Tried the furthest reaches of the basement without issue - at least 40-50 ft away with wooden studded walls/floors.
Pros: Easy setup/pairing, Bypass mode works fine to allow both sound bar and headsets. No lip sync delay when used in conjunction with compatible headset. Also, customer support is very good. Initially had an issue with a different headset that was causing an issue and not allowing Low Latency mode. Once I paired the device with an appropriate headset, everything was great.
Cons: Given my setup, when both headset and soundbar are used, there is a slight echo (time delay between the two devices) Do not notice any lip sync delay with either headset or sound bar when used individually but when used together there is a slight reverb. I suspect that this is due to my older model sound bar which is not "low latency". Not terribly bothersome for me but something to consider.
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.
