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

This is a 164FT LONG RANGE Bluetooth 5.0 Transmitter, Receiver and bypass (direct cable connection) 3-in-1 Device. Supports both wired (bypass mode) and Bluetooth output simultaneously.

Recommended Uses:

  • Transmitter -> Bluetooth-enable your TV, PC, AV receiver (e.g. Yamaha, Onkyo, Denon), TV Box etc. Stream audio to any Bluetooth headphones / speakers, e.g. Bose, Beats, Sony, Plantronics, Audio-Technica, Apple AirPods headphones.
  • Receiver -> Bluetooth-enable a wired speaker, soundbar, home theater etc. Receive audio wirelessly from any Bluetooth audio device e.g. PC, mobile phone, Echo, Echo Dot,etc.
  • Bypass -> If you have only ONE OPTICAL Output from TV, and it is currently used by your soundbar, you can use the BYPASS function. What’s more, your family can enjoy TV via Bluetooth headphones and a wired speaker simultaneously with independent volume control.
  • Volume adjust function can be used for many devices which do not have their own volume controls (e.g. Airpods).
  • Uses aptX low latency to eliminate lip sync delay. Uses aptX HD to get a ‘better-than-CD’ listening experience.
  • Supports aptX low latency with dual link for two headphones.
  • Compatible with devices with optical, RCA and AUX audio outputs.
  • Can use as a pair to extend range, one Oasis Plus use a BT transmitter, another one as a BT receiver

Doesn't work / not recommended:

  • This is a Class 1 Bluetooth transceiver - proven to reach up to 164'. However, your range will depend on your connecting device and other factors (see details below Q1)
  • For TV optical output - set audio format to PCM. Dolby / DTS are not supported.
  • Works as EITHER a transmitter or receiver - NOT simultaneously work as a repeater.
  • Multipoint support works best for on/over ear headphones. Not recommended to use dual link with TWS earbuds due to current technical constraints with TWS in general.
  • For non- aptX LL supported headphones / speakers, Oasis Plus will work with them using SBC or aptX codec with 70-200ms latency - Lip-sync delay could be noticed by sensitive users.
  • It doesn’t support aptX HD when dual link. NOT simultaneously supports aptX HD and aptX LL.
  • Not recommend for streaming live music (while playing guitar, keyboard, electronic drums etc.)
  • When using the transmitter the TV internal speakers might not work or become muted. This is TV dependent


Supports aptX HD both as a Transmitter or Receiver

Standard CD quality is 16bit. Using aptX-HD wirelessly stream 24bit music quality 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.






Wired & Bluetooth Simultaneous Support

The industry-leading “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.

5.0 out of 5 stars Genuine aptX low latency transmitter
Reviewed in the United Kingdom on 3 January 2020
I work from home and spend several hours a day in video calls. I am also a podcaster and have a Twitch channel where I live stream retro games. I wanted to untether myself from my desk while talking to colleagues, be able to access my second desk during meetings, stand up while podcasting and have greater range of movement while live streaming or go and make a cup of tea during a stream.

I have Behringer UMC202HD for hooking up an XLR mic, monitor speakers and earbuds. I was looking for a way to add a Bluetooth transmitter to the headphone out on the UMC202HD. I learned that aptX low latency was required on the transmitter and Bluetooth headphones. After researching Bluetooth transmitters, I settled on the Avantree Oasis Plus and am extremely pleased with the results.

I have the Oasis Plus (AUX) connected to the headphone out on the Behringer and toggled the OPT/AUX switch to AUX. I have the Oasis Plus permanently powered via the supplied USB micro cable connected to a spare USB port on one of my displays.

I've paired Shure SE215-CL-BT2 earbuds and Sennheiser Momentum Free earbuds (both aptX low latency) with the Oasis Plus. Pairing was quick and simple for both. Audio quality is excellent, no background hum or hiss. Both sets of ear buds can be connected at the same time. Not a feature I will use often, but handy to have. Most importantly, a switch on the side of the Oasis Plus allows you to set the aptX preference of low latency or HD. With low latency selected both earbuds respond with extremely low latency, and using audio/video sync tests on YouTube confirms that audio and video are aligned. Perfect!

I am able to wander to all corners of the house and stay connected to the Oasis Plus, with some brief dropouts when farthest from it. Long range is not a real requirement for me, but being able to wander off to make tea while keeping music playing is nice.

I have disabled to audio prompts from the Oasis Plus because I can see at a glance the status of connected devices by looking at it. The included instructions clearly explain how to use all the features of the Oasis Plus, such as clearing the pairing history.

I won't ever use the receiver capability or optical audio, so can't speak to that. But, as an aptx low latency transmitter it works brilliantly.
