Oasis Plus

Step 1: Connect the Oasis Plus to a power source using the Micro-USB cable we provided, and flip the power switch to "TX" position.   Step 2: Pairing your Headphones / Speaker to Oasis Plus. Please refer to THIS ARTICLE for a more detailed step-by-step instruction.   Step 3: Connecting to TV. The Oasis Plus supports Digital Optical, Auxiliary (3.5mm,) and RCA (RED/WHITE.) Please check and see which one your TV supports; any ONE of the three will work. Option A - Digital Optical Take the Optical Cable that we provided in the box, and plug one end of it into the "Digital Audio Out" or "Optical" port on the back of your TV. Plug the other end of the cable into the BLACK Optical Port on the back of your Oasis Plus transmitter. Make sure that the "OPT" indicator on Oasis Plus is now SOLID WHITE. If not, press the "AUX/OPT" button once (2019 version only. Pre-2019 version auto-changes.) Go to your TV's SOUND settings, make sure that the AUDIO OUTPUT has been set to "EXTERNAL SPEAKER." Some TVs automatically complete this step for you, some don't. Also in your TV's SOUND settings, make sure that the AUDIO FORMAT has been set to "PCM." Some TVs automatically complete this step for you, some don't. Option B - Auxiliary (3.5mm) Take the 3.5mm Auxiliary Cable that we provided in the box, and plug one end of it into the "HEADSET" or "3.5mm AUDIO OUT" port on the back of your TV. Plug the other end of the cable into the AUX Port next to the Antenna (the one closer to the BLACK Optical Port) on the back of your Oasis Plus transmitter. Make sure that the "AUX" indicator on Oasis Plus is now SOLID WHITE. If not, press the "AUX/OPT" button once (2019 version only. Pre-2019 version auto-changes.) Go to your TV's SOUND settings, make sure that the AUDIO OUTPUT has been set to "HEADSET." Some TVs automatically complete this step for you, some don't. Option C - RCA (RED / WHITE) Please note that ONLY the ones that are labeled "AUDIO OUT" can be used; the other ones won't work. Plug the RED/WHITE end of the RCA-AUX Converter Cable into the RCA AUDIO OUT port on the back of your TV. Take the 3.5mm Auxiliary Cable, and plug it into the BLACK end of the RCA-AUX Converter Cable. Plug the other end of the 3.5mm Auxiliary Cable into the AUX Port next to the Antenna (the one closer to the BLACK Optical Port) on the back of your Oasis Plus transmitter. Make sure that the "AUX" indicator on Oasis Plus is now SOLID WHITE. If not, press the "AUX/OPT" button once (2019 version only. Pre-2019 version auto-changes.) Go to your TV's SOUND settings, make sure that the AUDIO OUTPUT has been set to "EXTERNAL SPEAKER." Some TVs automatically complete this step for you, some don't. Now you should be good to go! Please either refer to the Video Tutorials below or email us at support@avantree.com if you have more questions!

Possible causes: 1. Both Transmitter and headphone / Speaker are not in PAIRING / Discoverable mode (Steps 1 & 2) 2. Wireless Interference from your smart TV or streaming gadgets such as Roku (Step 3) Step 1: Did you get your Headphone/Speaker into Bluetooth Pairing Mode? Powering on the Headphones/Speaker does not automatically put them in pairing mode. If it's not in pairing mode, it won't be "discoverable" by other Bluetooth devices. Please double-check with the info below OR your User Manual. For Avantree Headphones/Speakers: The LED indicator on the Headphone/Speaker flashing RED & BLUE. For Non-Avantree headphones/Speakers: Look them Up by Brand.Step 2: Did you get your Transmitter into Bluetooth Pairing Mode? For all Avantree transmitters, pairing mode can be recognized by the Rapidly flashing LED Indicator; the LED indicator will be flashing faster than its usual state. If you don't see that, please take a look at the user manual and try again. Both the Transmitter AND the Headphone/Speaker need to be in pairing mode in order for them to connect.   Step 3: Clear away any potential Wireless Interference Devices. Other wireless devices in the vicinity of the Avantree Transmitter Adapter may negatively affect the range. This "source of interference" can be a WiFi router, a TV box (Xfinity, Roku etc.), or even just another Bluetooth device. To solve this issue, simply TURN OFF the source of interference when you are trying. to do the pairing process.  Or you can take the transmitter and headphone to your car and pair them up there. The transmitter does not need the audio cable plugged in under the pairing process. Only a USB cable from car USB will be enough to power it up. Once paired, they should reconnect once both turned on again.  Step 4: IF Step 1, 2 & 3 don't work, please Reset and Clear Pairing History . It is not uncommon for Bluetooth devices (include both the Avantree Transmitter and the device you're trying to pair it with) to be interfered by other devices nearby. This prevents the two devices that you're trying to pair from quickly pairing with each other. If you suspect the situation to be caused by this, try resetting the devices you're trying to pair. Once successfully paired, the transmitter should auto-reconnect to your device every time both of them are turned on. If you're still having issues, please send us an email at support@avantree.com with the following info: 1. What Avantree transmitter you are using and what LED light you see under pairing mode; 2. What Bluetooth device you try to pair it with and how its LED light flashing under pairing mode; 3. Which one gets out of pairing mode first if they do not pair and connect.

The Oasis Plus is Compatible with... Transmitter Mode ANY Television that supports DIGITAL AUDIO OUT, AUX (3.5mm) OUT, or RCA (RED / WHITE) AUDIO OUT. ANY AV Receiver that supports DIGITAL AUDIO OUT, AUX (3.5mm) OUT, or one that has a PHONES port. ANY Bluetooth Headphone / Speaker. ANY Laptop / Computer with an AUX (3.5mm) Port. Receiver Mode ANY Mobile Phone / Tablet with Bluetooth Function. ANY Wired Speaker that supports AUX (3.5mm) or DIGITAL AUDIO IN. ANY Laptop / Computer with Bluetooth Function.

Well, we got that covered! What you need is a perfect fit for the unique "Bypass" function that's only available on Oasis Plus, HT5009, and HT5006! In short, the "Bypass" mode basically involves installing the Oasis Plus between your TV and your sound system (Sound Bar, AV Receiver...) This is often used under 2 scenarios: When the port (Optical or AUX) on your TV is already occupied by your sound system yet you would like to install the Oasis Plus. When you'd like to have your TV audio come out from both your Headphones (that are paired with Oasis Plus) AND your Sound System, so that your family / friends can enjoy TV as well. Setting Up the Bypass Mode Step 1: Connect the Oasis Plus to a power source. You may either flip the power switch to "TX" to turn it on or simply leave it as off. Step 2: Connect the Oasis Plus to your TV using one of the ports under the label "TX Input from TV" located on the back of Oasis Plus. Step 3: Connect the Oasis Plus to your Sound System (AV Receiver of SoundBar etc.) using one of the ports under the label "RX Output to Speaker" located on the back of Oasis Plus. Please make sure that you're using the same connection here as the connection you've used on the TX side. For instance, if you're using Optical Digital connection between your TV and your Oasis Plus, you'd have to use Optical Digital here as well.   Now, assuming that you've already paired your Headphones to your Oasis Plus beforehand, you're good to go! If you haven't done the pairing, please refer to THIS ARTICLE. Ways to use the Bypass function: Hearing from both your Headphones and your Sound System: Please make sure your Oasis Plus is ON and functioning on "TX" mode. Hearing from ONLY the Sound System: You may either turn your Oasis Plus off, or simply turn your Headphones off. Hearing from ONLY the Headphones: Easy, just turn your Sound System off.

Since the Oasis Plus does not have a built-in battery, it needs to be connected to a power source in order to power up. We suggest that you connect it to the USB port on the TV / PC / Receiver you're using the Oasis Plus with, so that it turns on / off with your TV / PC. If your TV does not have an USB port, you can power the Oasis Plus up with your cellphone USB adapter, as long as the adapter supports 5V / 500 mA – 2A. To power on, simply flip the power switch to either TX or RX position, depending on the mode you'd like to use.

Many Avantree products have incorporated the latest "aptx low latency" codec technology, for superior stereo quality sound without any noticeable delay (known as latency). What is aptX Low Latency - https://www.aptx.com/aptx-low-latency Certified aptX Low Latency device list - https://www.aptx.com/products?field_aptx_type_tid=484 * Important note* To take advantage of the better performance of aptX Low Latency codec, the other side Bluetooth device must support the same codec. If the other side device only supports the normal aptX codec, or the SBC one, these codecs will be used instead.        How about the audio delay when use different wireless audio codec? Wireless audio codec Audio delay aptX™ HD ≥ 250ms aptX™ Low Latency ~ 40ms aptX™ ~ 70ms FastStream ~ 40ms SBC (most standard Bluetooth audio codec) ~ 220ms Note: The latency for FastStream is almost the same as aptX Low Latency, but the audio quality of aptX Low Latency is better.

While Oasis Plus CAN be used with most AV Receiver, please DO NOT PLUG THE OASIS PLUS INTO ANY OF THE RED / WHITE PORTS ON THE BACK OF A RECEIVER! This may permanently damage the product. Step 1: Connect the Oasis Plus to a power source using the Micro-USB cable we provided, and flip the power switch to "TX" position. Step 2: Pairing your Headphones / Speaker to Oasis Plus. Please refer to THIS ARTICLE for a more detailed step-by-step instruction. Step 3: Connecting to AV Receiver There are 2 ways to connect the Oasis plus to your AV Receiver: DIGITAL OPTICAL OUT, or PHONES. Option A - DIGITAL OPTICAL Take the Optical Cable that we provided in the box, and plug one end of it into the "Digital Audio Out" or "Optical Out" port on the back of your AV Receiver. Plug the other end of the cable into the BLACK Optical Port on the back of your Oasis Plus transmitter. Make sure that the "OPT" indicator on Oasis Plus is now SOLID WHITE. If not, press the "AUX/OPT" button once (2019 version only. Pre-2019 version auto-changes.) Option B - PHONES (Usually on the front of the AV Receiver) Take the 3.5mm Auxiliary Cable that we provided in the box, and plug one end of it into the PHONES Port on your AV Receiver. You'll need to use a 6.35mm to 3.5mm converter here (needs to be purchased separately.)   Plug the other end of the cable into the AUX Port next to the Antenna (the one closer to the BLACK Optical Port) on the back of your Oasis Plus transmitter. Make sure that the "AUX" indicator on Oasis Plus is now SOLID WHITE. If not, press the "AUX/OPT" button once (2019 version only. Pre-2019 version auto-changes.) For more questions, please send us an email at support@avantree.com, we'll have someone assist you as soon as possible.

When working as a Transmitter (Headphones, Speakers; Bluetooth Enabling a TV or an AV Receiver) You may adjust the volume via the "+" and "-" buttons directly on the Oasis Plus transmitter. This can ONLY be done if your headphone/speaker supports AVRCP (most of the ones with volume adjustment buttons do.) You may adjust the volume on your bluetooth headphone/speakers if they have volume adjustment buttons you may adjust the volume directly via your TV / AV Receiver's remote control. But some TV's volume will be fixed once you plug in an audio cable.   When working as a Receiver (Mobile Phones, Tablets, Laptop; Bluetooth Enabling a Speaker) You may either use your Mobile Phone / Tablet / Laptop to adjust the volume directly. You may also use the "+" and "-" buttons on Oasis Plus to achieve the same results. When working in Bypass Mode (Wired Connection, between a TV and a Soundbar / Speaker) You may use your Soundbar / Speaker's remote control to adjust the external speaker volume, and use the volume adjustment buttons on your Headphones to adjust headphones' volume. The volume buttons on Oasis Plus does not function under this mode. If you have more questions, please email us at support@avantree.com, we'll have someone assist you shortly.

Note: The TX mode and the RX mode each function seperately, so please make sure that you're in the correct mode. Step 1: Power on the Oasis Plus. Flip the power switch to either the TX or the RX position, depending on the mode that you'd like to reset. Step 2: Factory Reset. Press and hold the "+" and the "-" buttons together for 7 seconds. Please do NOT release the buttons until you hear a “Pairing history cleared” voice prompt - an indication of successful reset.  Once this is done, the Oasis Plus will re-enter pairing mode, as indicated by the "TX" LED indicator flashing GREEN & WHITE.     Related knowledge: 1.Bluetooth device normally auto-reconnects to its LAST paired / connected device. You might need to make sure the previous used device are Bluetooth-off to avoid interference. 2.It is important to Reset both Bluetooth sender and receiver. In case of cellphone / PC, you can turn off its Bluetooth function and turn it back on. 3.If still not working, you can email us (support@avantree.com). We will help you to fix it.

Hearing audio through the TV speaker AND the headphones at the same time If you'd like to get sound on both your TV speakers AND headphones at the same time, it DEPENDS on whether the TV is able to support getting sound out to two sources simultaneously. It is NOT related to the transmitter. The transmitter receieves the sound from your TV's output and streams it over to your Bluetooth headphones or speakers. However, if you connect the transmitter to your TV via OPTICAL port and you can see the following options under the SOUND OUTPUT settings on your TV... You can actually get sound simultaneously! Follow these steps: Go to SOUND OUTPUT and change this to OPTICAL / EXTERNAL SPEAKER Once there's sound going out into the headphones, go back to SOUND OUTPUT and change this back to TV SPEAKER If your TV doesn't support simultaneous output to both the TV speakers and headphones, here are some alternative methods you can consider: For Audio Transmitter Users: Solution 1: Connect the Transmitter to a TV box / AV Receiver instead If you have a TV box (DirecTV, Xfinity, Bluray Player, etc.), you should be able to find audio output ports on the back of them. Try to connect the Avantree transmitter directly here instead of the TV. This method essentially allows you to "go around" the TV's built-in speakers. Con: will not work on streaming apps if you have a Smart TV or streaming device For all users: Solution 2: For users with TV Sondbar / AV Receiver 2.1 Use Transmitters with Passthrough Function If you have a Soundbar or Stereo Receiver, check your transmitter to see if it supports passthrough. If not, you can return your current product and consider purchasing one of these: Orbit, Oasis Plus, Opera, Medley 6018, HT5009, HT5006, Duet, or Quartet. Our industry leading "Passthrough" function allows you to put the transmitter/base between a TV and an external speaker and have audio come out from both devices AT THE SAME TIME. 2.2 Use Audio splitter/extractor For AUX Output - Use an audio splitter (e.g. Avantree TR302) to share the TV's audio between an EXTERNAL SPEAKER and the Transmitter. The splitter in this example is a 3.5mm audio splitter For Optical AUDIO OUT - Use an optical splitter (e.g. J-Tech splitter) to share the TV's audio between an EXTERNAL SPEAKER and the Transmitter. The splitter in this example is an optical audio splitter. For HDMI ARC OUT - Use an HDMI Audio Extractor (e.g. HAX05) to share the TV's audio between an EXTERNAL SPEAKER and the Transmitter. The splitter in this example is an ARC supported HDMI audio extractor.

If you cannot adjust the volume of the headpones, you can try the following:1. Firm click the outer side of the (+/-) buttons on the headphone instead of the middle button. Do not long press or do not hold down.2. It may take multiple quick taps of the (+/-) buttons to hear the volume change. 3. (Often!) Due to a one-off Bluetooth connection error. Fix by pairing & connecting the headphone with your cellphone first and then use with the transmitter again 1) Turn off the headphones and the transmitter2) Pair the headphones with your cellphone and adjust volume - Please make sure that the headphone has been turned OFF. While it's OFF, Press & Hold the Multi-Function Button (the middle button, between + and -) until the LED flashes RED & BLUE alternately. You should also hear a "Pairing" voice prompt from the headphones. Then turn on Bluetooth on your Mobile Device. Search & Select the headphones to connect.                                           The headphones may show up as HT3189, HT4189, HT5009, DG59, or simply AS9S, depending on the product you have.3) Turn bluetooth off from cellphone and use it with the transmitter again. Note: Starting from batch T23H2, both clicking or holding the volume button will adjust the volume. If still no luck, please fill this Verification Form so we can help you further.

First-Time Use: If the Oasis Plus is brand new, and this is your first time using it, it should automatically enter pairing mode when you turn it on. You'll see the "TX" LED indicator flashing GREEN & WHITE. Non-First-Time Use: If this is NOT the first time you've used it, simply enter it into pairing mode manually by Pressing & Holding the Bluetooth Icon Button (1st "round" button from the left) for 2 seconds. You'll see the "TX" LED indicator flashing GREEN & WHITE. In Both Cases, you should hear a "Pairing mode - Please put your device into pairing mode and wait" voice prompt from Oasis Plus.   If you're still confused, you may either refer to one of the Video Tutorials below, or email us at support@avantree.com, we'll have someone assist you immediately.

Here are a few things you'd want to know about Bluetooth... 1. Bluetooth by nature is a short-range wireless technology. Bluetooth was initially made specifically for wireless headsets hence its “range” was never meant to be anything more than the length of a typical backyard. 2. Bluetooth Signals are easily interfered with. Much like almost any other modern wireless technology, Bluetooth signals can be negatively affected by things like walls, floors, other wireless devices, or even a human body. If you want a better range & less interference, try to stay clear of the things mentioned above. 3. There are two types of Bluetooth. In short, they are “Class 1” and “Class 2.”  Class 1 has better range (100m/300ft) but drains your battery faster, whereas Class 2 has a shorter range (10m/30ft) but is more efficient when it comes to battery usage.   4. The “Actual Range” depends on a lot of things. Things that can affect the range: Bluetooth version, Bluetooth type, Bluetooth profile, Brand & make, where you’re using it, what’s around you… etc and many more. Getting a bad range doesn’t necessarily mean your device is bad; try it elsewhere before you give it a conclusion. 5. The “Transmitter” and the “Receiver.” Every Bluetooth connection consists of a “transmitter” and a “receiver.” The “transmitter” sends the signals to the “receiver.” In a typical Bluetooth headphone connection, your phone is the transmitter and the headphone is the receiver. There are cases where one device can do both, but it is unlikely that they’ll be able to do both at the same time. Here are some examples: Transmitters: Phone, Computer (can sometimes use as receiver), TV. Receiver: Headphones, Speaker

Nowadays, many hearing aids do not support third party Bluetooth transmitters. To confirm if yours are compatible with Avantree Bluetooth transmitters, please check the following - 1. When you pair your hearing aids with your iPhone or Android phone, do you need to use an app? 2. In your app, do you also need to use the other functions, e.g. Accessibility function from Settings menu? 3. Can your hearing aids enter pairing mode (rapidly flashing RED & BLUE)? If your answer to questions 1 and 2 are YES, but NO to question 3, then your hearing aids will most likely NOT work with third party Bluetooth transmitters. If your answer to question 3 is YES, then, it is likely that your hearing aids can work with third party Bluetooth transmitters. Of course, the easiest way to find out is to ask your hearing aids company this question - "Will my hearing aids working with other brands' Bluetooth transmittters?". If the answer is YES, then you can use with it with Avantree Audikast plus, Avantree Oasis Plus, as well as Avantree Orbit. Even if your hearing aids cannot pair up with our Bluetooth transmitters directly, an alternative solution is to have a pair of wireless over-the-ear headphones and wear them over your hearing aids. You can search for Avantree HT5009 or Opera. For your reference, these hearing aids have been confirmed to work with our transmitters: Phonak ComPilot, Com Dex receiver with Widex hearing aids, Oticon ConnectClip with Oticon More miniRITE R.

In short, YES you can definitely use your Airpods with our transmitter Connecting your AirPods to the Transmitter: Step 1: Turn OFF the Bluetooth on every device that's previously connected to your AirPods. Step 2: Put your AirPods back into its case. Step 3: Get the AirPods into Pairing Mode. Close the lid and flip it open again. Press & Hold the button on the back of the charging case until the little LED light starts flashing WHITE. Step 4: Put your Avantree Bluetooth transmitter into Pairing Mode as well. Please refer to its user guide if you're not sure how. With both devices in pairing mode, keep them close to each other and give them a few seconds. Please check their respective LED indicators to make sure that they've connected. If no luck to get them paired, please Factory Reset/Clear Pairing History of both devices and try again.  Step 1: Factory Reset Airpods: 1. Put your AirPods in their case. Close the lid. Wait 30 seconds, then open the lid. 2. On your iPhone, iPad, or iPod touch, go to Settings. Go to Settings > Bluetooth and tap the "i" icon next to your AirPods. (If you don't see your AirPods in Settings > Bluetooth, just go to the next step.) Then tap Forget This Device, and tap again to confirm. 3. Reset your AirPods With the lid open, press and hold the setup button on the back of the case for about 15 seconds, until you see the status light flashing amber. 4. Reconnect your AirPods With the lid open, place your AirPods close to the transmitter.  Step 2: Factory Reset Avantree Bluetooth Transmitter: Please refer to its user guide if you're not sure how.Once this is done, the Oasis Plus will re-enter pairing mode.   Volume Control:  If you're using Optical Connection: You won't be able to adjust volume via your TV remote controls. We recommend using Oasis Plus or Audikast Plus; the volume control buttons on them will allow you to control the volume at will. If you're using AUX (3.5mm) or RCA (Red/White) Connection: You may adjust volume via your TV's remote control. If you're using USB Connection: We recommend DG40s/DG50/Audikast/Priva III. You can adjust the volume on PC.  In case you prefer Learning through Videos:     Please contact us at support@avantree.com if you have questions.

Before pairing, please note that Bose products currently do NOT support aptX-Low Latency codec, hence there will be lip-sync delays when used to watch TV/Video. You may utilize an aptX-LL Bluetooth receiver to eliminate this issue. Step 1: Get your Bose Headphone / Speaker into Bluetooth Pairing Mode. Different products tend to have a different-looking pairing mode... but not to worry, see below for the pairing mode for a list of Bose's most popular products. Bose QuietComfort 35 (QC35): With the headphone ON, slide the power switch to the Bluetooth symbol and hold it there until you hear “Ready to connect” or the Bluetooth indicator blinks Blue. Bose 700: With the headphone ON, press & hold the power button for 3 seconds to put the headphones into pairing mode.

This "source of interference" can be a WiFi router, a TV box, or even just another Bluetooth device. To solve this issue, simply move either the transmitter or the source of interference away; that ought to clear the problem. Method 4: Check the Operation range of the other Bluetooth device. Certain Bluetooth devices have much shorter range; this "feature" is especially obvious on smaller Bluetooth devices like True Wireless Earbuds. If this is the case, the only real solution is to simply go with another Bluetooth device - one that has a better range. Method 5: Avoid Physical Objects. Walls, solid materials, or even human bodies can all become "obstacles" that negatively affect the Bluetooth device's range. Try clearing the space between your Bluetooth devices, and see if that helps.

Audio latency is, essentially, the time it takes for audio data to move from your audio source to your headphones. Wired headphones produce an imperceptible amount of lag—about 5-10ms worth. Within this 5-10ms window, your phone or computer processes the digital audio data, converts said data to an analog audio signal, and then streams the signal through your headphones or speakers. Bluetooth devices spend a lot more time to do this “processing”. The source device compresses the data and wirelessly transmits it. Then the headphones or speakers receive the data and decompresses it. The wireless communication program is called a “Codec”. It acts like a specific language that the sender and the receiver agree to communicate with. Different codecs lead to different audio delay times. Bluetooth Audio Codec Audio delay aptX™ HD  ≥ 250ms aptX™ Low Latency ~ 40ms aptX™ ~ 70ms FastStream ~ 40ms SBC (Sub Band Codec) ~ 220ms   To benefit from the lowest amount of audio delay, BOTH the sender and the receiver must support either the aptX Low Latency or the Fast Stream Codec. If only one side supports aptX Low Latency but the other side does not, the streaming will use the next available codec supported by both devices, such as SBC or aptX. You will find that your Bluetooth audio and TV speaker audio are not in sync.   How do you confirm whether your Bluetooth headphones support the aptX Low Latency or FastStream codec? Simply check its specifications in its product listing or manual. Apple Headphones and nearly all true wireless earbuds do not support aptX Low Latency. Some headphones claim that they do, unless they are a reputable brand, you still need to double check from  Certified aptX Low Latency device list from www.aptx.com.   There is another factor that you need to keep in mind regarding audio delay, which is Codec priority. Many Bluetooth devices have a Codec "priority" list, meaning that it prioritizes using some Codecs over others when connecting to other devices. For example, the DG80 Dongle's Codec priority goes like this: 1.FastStream, 2.aptX low latency, 3.aptX, 4.SBC. When connecting with other devices, the dongle will go through these codecs one by one until it finds one that is supported by the device it's connecting to.   Where this gets tricky is if you are connecting multiple devices to each other. Bluetooth devices will use the lowest common denominator supported by all devices, not necessarily the fastest codec. This can result to a slower codec being used, even though your headphones support a faster codec. Read more here.   If you suspect that this is an issue, a fix is to factory reset / clear the pairing history of the devices experiencing audio delay. This may fix the issue.   What if my headphone is not low latency supported? You have the following options: 1. Change to a Low Latency supported headphone; 2. Get a headphone / transmitter Set. We have plenty of options HERE.  3. Live with the slight lip sync delay. 

Bluetooth and Wi-Fi devices use the same radio frequencies to communicate, so, they often interfere with one another and are prone to interference from other devices operating on the same frequencies. Please try this simple fix:1. Switch off the internet.2. Turn on the Avantree transmitter and headphones and leave for 15 mins.3. Turn on wifi router which will detect frequency used by Avantree and automatically select a different frequency.If it does not work, there are other things you can do if you are experiencing interference on your Bluetooth or WiFi devices. These include:1. Moving your WiFi base station to an area in the house where there is less structural interference. There are now apps available online that will scan your wireless space for you, tell you the best place to set up your base station, and even suggest the best frequency to operate on.2. Resetting your transmitter. When you do this, it will automatically look for and default to the channel with the least amount of traffic and interference.3. Reducing the number of wireless devices operating on the network. In an office, this could be done by relocating some employees to a separate WiFi network within the building, while at home it could be achieved by regulating family WiFi usage or plugging some devices directly into the router via cables.  

If you use AT&T U-verse as your main TV source and you can't get a sound through your Bluetooth Headphones/Speaker, please follow the methods below to troubleshoot. Method 1: Adjust the HDMI Input Format. Click the MENU button on your AT&T Remote Control. Scroll down and select Options. Choose "Audio/Language". Go into "Digital Audio Output". Select STEREO and then hit Save. Adjust Settings on your Actual TV (Samsung, LG, Sony... etc.) Look them up by Brand. Method 2: Check the back of your U-verse Box, Use a Built-in Audio Port Instead. If Method 1 didn't work, try this. All U-verse boxes should have some sort of audio output port on the back. Plug your audio adapter into one of these instead of the ones on your TV. If this still doesn't work, please give us a call or contact us at support@avantree.com.

Here is step by step Video guide FYI - No Sound when watching Apple TV - How to FIX? Step 1: Click the MENU button on your Apple TV remote  Step 2: Scroll down and select "Settings"  Step 3: Scroll down and Select "Video and Audio" Step 4: Scroll down and Go into "Audio Format" Step 5: Click on "Change Format" Step 6: Choose "Change Format" again Step 7: Click on "New Format" Step 8: Change it to "Stereo" Step 9: Adjust Settings on your Actual TV (Samsung, LG, Sony... etc.) Look them up by Brand.

Step 1: Factory Reset & Turn OFF. You want to Factory Reset the Transmitter Adapter AND turn it off right after it's been reset. Do NOT give it a chance to reconnect to your neighbor's device again. Step 2: Get your Headphone/Speaker/Receiver. Turn it on and get it into Bluetooth Pairing Mode. For Avantree Headphones/Speakers/Receivers: The LED indicator on the headphone/speaker/receiver flashing RED & BLUE.For Non-Avantree Products: Look it up by Brand. Step 3: Turn on the Avantree Transmitter. Now you may turn it on. Since your Headphone/Speaker/Receiver is closer in proximity, it should pick yours over your neighbors.If it still somehow manages to connect to your neighbor's device... Try step 4. Step 4: Do the Pairing Elsewhere. Go somewhere that's not in the range of your neighbor's device and try again.Of course, there's also the option of knocking on your neighbor's door and ask him/her to turn the device off...   Hope this helps!

If you're using one of the latest Samsung Smart TVs, you could encounter an issue when using Bluetooth Transmitters or Headphones. The issue is due to the fact that Samsung Smart TVs tend to pair with any Bluetooth devices it can find unless you manually deny the connection.  This could lead to odd behaviors on your Samsung TV such as no picture, Blue / Black Screen with an error message, TV headphones and base not reconnecting, no sound on TV headphones, transmitter cannot pair to headphones, etc.  Bear in mind when using Samsung Smart TVs:  If your headphones / transmitters suddenly stopped working with your TV, it may be because your Smart TV performed an automatic update and reset all of its settings to its original form. Smart TVs also do automatic updates because they are connected to your Wi-Fi, just like a computer. Even though you didn't do anything, the TV changed itself. In these cases, follow the steps from the beginning to troubleshoot the issue. The TV remote control does NOT turn TV off. It only puts the TV into standby mode. The TV will still perform its "Smart" functions in standby mode. For example, the Samsung TV will still aggresively connect to all devices it finds. The best way to turn the TV OFF is to physically switch it OFF or to pull the plug. Here is the FIX for the above issue with Avantree TV headphones and transmitters. REMOVE / DENY the Avantree Device from Samsung TV's "External Device List." Keep the TV OFF (Not in Standby) if you have any issues reconnecting the headphones and the base.  DENY the Device: When the Samsung Smart TV detects your Avantree Device, a popup will appear on the screen, asking you to Allow or Deny the device to connect to the TV. You MUST DENY the device from connecting, otherwise it will not be able to connect with the other device in its set. REMOVE the Device: If you did allow the device to connect to your TV, or if your device connected to your TV automatically, you will need to remove the device from within your TV's settings. Settings >> General >> External Device Manager >> Device Connection Manager >> Device list - >> Edit >> Select all Avantree Device >> Delete After removing / denying the Avantree device from the Samsung TV's external device list, your Avantree devices should work properly now. If not, you might need to re-pair & lock the headphones with the base again. Here is how to do it: 1. Turn OFF your Samsung Smart TV. Either flip the physical switch on the TV, or pull the plug from power. If you cannot physically turn OFF your TV, an alternate method to try is to press and hold the power button on your TV remote for 6 seconds until the TV turns off. 2. Turn on your Headphones and Transmitter. It is recommended to have your transmitter plugged into a wall outlet, not your TV, as the TV should be off at this point. 3. Get the Headphones and Transmitter into pairing mode (rapidly flashing RED & BLUE). For more information, please refer to your devices' user manual or support site.  4. If your Headphones and Transmitter have a LOCK function, please LOCK the headphones and the transmitter together. For more information, please refer to your devices' user manual or support site. Now, the headphones and transmitter will be locked together, so that the next time you use them they should automatically re-connect with each other and show solid BLUE on the headphone. NO need to re-pair them each time. If this does not fix it, pls contact support@avantree.com.

You need to clear the pairing history by press and hold the + and - at the same time for 7 seconds until the device says 'pairing history cleared.'

If you are unable to connect a Bluetooth headphone / speaker to your Avantree transmitters, try the following: 1.     Turn your smart TV, as well as other close by wi-fi device off to avoid interference.  2.     Make sure the previous paired devices, e.g. Mobile Phone, PC, are Bluetooth-off. 3.     Make sure you put the Bluetooth headphones / speakers into PAIRING MODE (most people failed here!) 4.     Factory Reset (Clear pairing history!! Not only turn on / off) BOTH devices and try again.  5.     If you tried all above but still cannot pair, there might be an unknown aggressive Bluetooth device in your environment. You may try the pairing process in a different location. If both devices are portable, take them into your car, drive a bit away from home, and use car cigarette lighter as the power source and pair them up. Normally, if the transmitter / adapter leaves the pairing mode first, it indicates you have something else in the environment disturbing the pairing. Please clear pairing history of the transmitter or try from a different location) If the Bluetooth headphone / speaker leaves the pairing mode first, it indicates previous paired device is not turned off. Please check the manual and clear the pairing history of the device.  If both devices stay in pairing mode for a long time but not connected, it is most likely caused by wi-fi interference.   If it is still not working, please submit the Cannot Pair Verification Form, and we will get back to you within 1 working day. 

We have found that Sennheiser's HD-350BT, HD450BT, and CX350BT seem to have connectivity issues with our Trasmitter Adapters.Common complaints include: Hard to reconnect Connects but takes a while for sound to come through Transmitter shows it's connected via LL but there's still significant audio lag Cracking noise Our testing results have shown that the connectivity issues and the audio lag issue often disappear after a few reconnections. Nonetheless, other customers have contacted Sennheiser about this, and Sennheiser have admitted that they have some firmware issues (further confirmed on the three headphones' Amazon reviews).

This is particularly an issue when you're using the Digital Optical Audio output port for the Transmitter Adapter. Nowadays, most movies & TV shows have Dolby Digital Sound - Generally speaking, Bluetooth technology can only handle stereo sound and not Dolby, DTS, etc (except for our Orbit/TC580). Here's the fix:  1. Open Netflix/Prime on the TV first (VERY IMPORTANT) Netflix Prime 2. Get your TV remote and press Settings to go to Settings (while in Netflix/Prime) Netflix Prime 3. Set your Audio Output to PCM. Here's how to do it with Samsung TV as an example. Go to Sound >> Expert Settings >> Digital Out Audio Format >> PCM Netflix Prime 4.

Many people use external soundbar with their TV for a better audio experience. When a soundbar is involved, we suggest one of the following models for wireless audio streaming: Output to Soundbar (Wire Connection) & Bluetooth Headphones (Wireless Connection) Simultaneously One at a Time TV Headphone Set Opera,HT5009, HT5006, Quartet, Duet, Shift NA Bluetooth Transmitter Orbit, Oasis Plus TC419   For those soundbar connected with TV via optical cable, the recommended connection is: TV optical out <- Optical cable 1 -> Avantree Transmitter from TV OPT in (black port) / To Speaker OPT out (gray port) <- Optical cable 2 -> Soundbar OPT IN, here is the Reference Connection Diagram:     NOTE: 1. When you use this connection, make sure NO HDMI cable plugged in your soundbar. Only connect the soundbar via optical cable.             2.

Why is this happening?  In general, the dual linking of 2 TWS earbuds with 1 transmitter has some interoperability issues - as far as we know ALL transmitters on the market are facing the same difficulties. Bandwidth issues: in both of the TWS connections - one earbud (L/R) from each TWS needs to maintain a 'dual link' connection - one link to its L/R partner and one link to the transmitter. In addition, the transmitter itself must maintain a 'dual link' connection - one link for each TWS pair. In effect, there are 3 active 'dual link' connections taking place and in this scenario, due to bandwidth limitations there is often data packet loss leading to unstable connections. Incompatibility issues: from Apple's W1 chip to Qualcomm's many offerings, there are currently dozens of different chipset solutions on the market. Although all operate under the Bluetooth standard, variances in design often leads to incompatibilities and connection issues. Another case in point, if you Google "TWS multipoint" - you will find that most TWS earbuds also have multipoint issues and cannot maintain active connections to 2 devices simultaneously.

To turn the voice prompt ON/OFF, PRESS & HOLD the 2nd "Round" button from the left for 7 seconds. You will hear a "Voice Prompt ON" or a "Voice Prompt OFF" notification from the Oasis Plus. Please note that voice prompt of TX and RX modes are each independent, so please make sure that you're in the correct mode before doing so.  If you're still not sure how, please email us at support@avantree.com, we'll have someone assist you as soon as possible.

The reason why your headphones' volume is not able to be controlled by the transmitter is because they don't have the AVRCP protocol. To be able to do so, you will need to have an Avantree Orbit. Then, do the firmware upgrade here: Optional Patch for Orbit(TC580) - Fix Cannot Adjust Volume Issue with No AVRCP/Bluetooth Remote Control Headphones (V5.11). This DFU is specially designed to solve this issue. This is the only way to have it adjust your volume. Let's say you have an upgraded Orbit now. There is one other thing you need to do before you connect your headphones to the Orbit. You will need to connect these headphones to your phone first and increase the volume there. Otherwise it would be too low to be adjusted on the Orbit even if you've set the volume to max on the Orbit.

Here are a few typical set ups for your reference: Reference Connection 1  Use the AVR's Phones Output   AV Receiver Headphone port <- 6.35mm-3.5mm adapter + 3.5mm/AUX cable -> [Avantree Transmitter] AUX in from TV port ...... Headphones  Pros:  1. Easy to set up 2. No need to adjust the TV's audio format 3. Listen to all audio through the AV receiver / Sound bar, not just the TV program Cons:  Mutes the AVR speakers   Reference Connection 2 Use Optical Cable to connect the TV and AVR (Passthrough Function of Avantree Transmitter)   TV optical / digital out <- optical cable -> [Avantree Transmitter] Optical in from TV (Black) | Optical out to speaker port (Gray) <- optical cable -> Soundbar / AV receiver optical in        Pros:  1. Both the speakers and wireless headphones will have sound 2. Supports audio from all TV programs Cons:  1. Not all Avantree transmitters can do this; the ones that have this feature so far: Oasis Plus , HT5009, HT5006, Orbit , Opera , Medley Clear, Duet, & Quartet 2. Need to set the Audio format on the TV to PCM except when using with the Orbit. As a result, you can't get surround sound through the AVR speaker. Reference Connection 3 Find an audio output on the AVR which can work with your soundbar at the same time such as the Zone 2 RCA output port (analog audio out) or the Zone 2 HDMI output (digital audio out). In order to ensure that the Zone 2 port works, please check the manual of the AVR for how to set up Zone 2 first.For RCA output port(Analog audio out port), please make sure its output power fits our transmitters' AUX input requirements: 1. Max input level: 2000 Vrms    2. Input impedance < 64ΩIf you're not sure, please check with your AVR's manufacturer, or you can try to plug a pair of wired headphones into the RCA port. If you can get sound through the wired headphones as normal, then the RCA port will work with our transmitter.    For Zone 2 HDMI output (digital audio out), you will need an additional HDMI converter to connect with the Zone 2 HDMI port.  https://avantree.com/hdmi-audio-extractor-converter-hax04   Pros:  Keep Surround Sound 7.1 / 5.1 to your speakers with the Avantree Transmitter and TV headphones working at the same time  Cons:  May need to get an extra HDMI Audio Extractor  Not every AVR has these ports in the back If none of the above reference designs work for you, or you have other suggestions, we love to hear from you.
