2 Turn on both the transmitter and earbuds

Turn on the transmitter – Slide ON/OFF switch to ON, all LED indicator lights up for 2 seconds.

Turn on the earbuds – Remove earbuds from the case. One earbud will enter PAIRING MODE with the LED flashing BLUE.

Keep the transmitter and earbuds together, give them a few seconds, once connected, both the LED indicator on the earbuds and the   next to   on the transmitter turn SOLID BLUE, you hear “Connected”.

By now, your transmitter should be connected to your TV / Audio source (Part 1).

Your headphones and transmitter are paired and connected (Part 2).

This Step 3 is to make sure the compatible audio signal is received by the transmitter.

If you are using RCA or AUX connection, you need to adjust TV Sound OUT to 'Headset' or "External speaker".

Audikast Transmitter:

Power the transmitter using the USB cable provided. Connect it to a TV USB port (TV must be ON to provide power) or any other 5V/500mA-2A rated USB charger (e.g. your phone charger should work).

TWS106 Earbuds:

If you hear the voice prompt say "Low battery, please charge", you will need to charge your earbuds.

Charging the earbuds in the charging case

Place the right and left earbud in their respective positions in their charging case.

The LED on both earbuds will light up BLUE to indicate that they are charging, then automatically turn off when charging is complete. It takes about an hour to fully charge the earbuds in the case.

Charging the Case

Insert the USB C (smaller) end into the charging port on the back of the case and the USB end into a power source. You can either use the included charging cord or any USB C charging cable to charge.

When plugged in, the LEDs on the front of the case will flash WHITE according to the current battery level.

If the left-most LED flashes WHITE 4 times, it means that the battery level of the case is less than 25% and you will need to charge the case.

When the case is fully charged, all four LEDs will light up WHITE for about 5 minutes then turn off.

The fully charged earbuds can last up to 7 hours, while a fully charged case can charge the earbuds 15-16 times, providing up to an additional 113 hours of play time. While the case is charging, it will also charge the earbuds inside the case.

Double-click  on the right earbud to turn the volume up and the same on the left to turn the volume down.

Normally, size M earbud tips work for most people, and they are what come on the earbuds. So if they do not fit you, please do the following:

1. Choose a snug-fitting pair of earbud tips.

2. Insert earbuds and adjust for secure fit.

TWS106:

Step 1. Put both earbuds back into the charging case.

Step 2. Press & hold both  buttons for about 8s, until the LED flashes BLUE 3 times then turns off.

Step 3. Remove both earbuds from the case, keeping them close together so they connect to each other. When complete, the LED on the RIGHT earbud should flash BLUE faster than the LEFT earbud.

Step 4. Earbuds are now reset.

Audikast Plus:

Step 1: Power on the Audikast Plus

Connect the Audikast Plus to power, and flip the power switch to “ON”.

Step 2: Factory Reset

Press & hold the "+" and "-" buttons simultaneously for 7 seconds. You'll see both Bluetooth LED indicators light up PINK and turn off, indicating that the reset was successful.

Once this is done, the Audikast Plus will re-enter pairing mode, as indicated by the Bluetooth icon next to "A" flashing RED & BLUE.

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. 

Step 1. Remove earbuds from the case. One earbud will enter PAIRING MODE with the LED flashing BLUE.

Step 2. Go to Bluetooth setting on your mobile device. Search and select "Avantree TWS106R" or "Avantree TWS106L" to connect. After connecting, your device will display "Connected" and the LED will turn off.

Step 3.  Please DO accept the pop-up pairing request from your device. Now you can stream music.

Once paired successfully, they will auto reconnect with the LAST connected device once they powered on. If not, please click "Avantree TWS106R" or "Avantree TWS106L" on your device to manually reconnect.

To change the earbud tips of the TWS106 earbuds, firmly grip the earbud tip, and pull it off of the earbud. Then, take your replacement earbud tip, line them up with the earbuds, and then push them on until they are in place.
To change the earbud fins, grab the fin and gently pull it off of the earbud. Then, take your replacement earbud fin, and line up the groove on the inside of the fin with the rectangular obtrusion on the earbud. Wrap the earbud fin around the earbud until it is properly installed. Take care to properly line up the fin, otherwise it may not fit back into the charging case.

If you want to use one earphone each time with a same device,

1. Make sure you have previously connected the earphones with your device as a TWS pair first
2. For subsequent use, just remove either earphone which you want to use from the case and it will auto-reconnect to your device.

If you want to use one earphone each time with two different devices,

1. Remove Left Bud ONLY, and Pair it with Device A
2. Put the Left Bud back to the charging case and close the case. Make sure Device A is Bluetooth-OFF! 
3. Remove Right Bud ONLY and Pair it with Device B 
4. Remember which bud paired with which device

Note: Use EACH individually with A / B. (Do NOT remove the two buds from the dock at the same time.)

Behavior of Avantree Transmitter - When turned on, it will keep looking for its last paired devices. It will keep scanning for a while, it will either find and connect to it or give up and go to standby mode. If you want to connect again under standby mode, you can click on the "Reconnect" button. If you want to search again, you can click on the Bluetooth pairing button ONCE to initiate the reconnection. Once found, the Bluetooth device and transmitter reconnection will take a few seconds to pair.

Normal behavior of non-Avantree Bluetooth devices (generally speaking) - When the headphones is turned on, it will automatically looking for its last paired device. If not found, it will enter standby mode. If you want to search again, you can click on the Bluetooth pairing button ONCE to initiate the reconnection. Once found, the Bluetooth device and transmitter reconnection will take a few seconds to pair.

Normally you do not need to re-pair your Bluetooth Headphones or Speakers with the Avantree Transmitter every time. Once successfully paired, they should automatically reconnect when both devices are turned on (please wait 5-10s). If not, please try the following:

Firstly, turn both transmitter and headphone OFF . Also TURN Bluetooth function OFF on all previously paired devices. 

1.     Turn both transmitter and headphone off. Turn them back on and WAIT for 5-10s. 

2.     If they do not reconnect, click the pairing button on the headphone(silver button) once and wait again for 5-10s.

3.     If still no luck, click the pairing button on the transmitter once and wait for 5-10s. 

If your transmitter is connected to TWO Bluetooth devices, the repair process is as follows:

1.     Turn on the transmitter and device 1. Wait for them to reconnect;

2.     Turn on device 2. Click pair button once on the headphone and wait for 5-10s. 

3.     If not, click the pairing button on the transmitter once (toggle switch is one push to the pairing side)

If you prefer to use a different Avantree headphone as the primary in your Avantree TV headphone set, you can do so easily

1. Turn all three devices off
2. Turn on the transmitter and put it into pairing mode
3. Put the intended-to-use-as-primary headphone into pairing mode
4. Wait for them to pair & connect
5. Lock them up with the locking method of the set. 

The eabruds and the transmitter in the HT4130 set are "factory locked." This means that they should automatically connect with each other right out of the box (with both devices turned on, of course.)

If they fail to connect, please try to click the button once. If they still cannot reconnect, please follow the steps below to RECONNECT and LOCK them again.

1. Get the Avantree Audikast Plus transmitter into Pairing Mode

• Connect the Audikast Plus to a power source and turn it on.
• Press & Hold the button  until you see the Bluetooth indicator flashing RED & BLUE.
  

2. Get the earbuds into Pairing Mode.

• Open the charging case and remove the earbuds from the case.
• One earbud will enter PAIRING mode with the LED flashing BLUE.

3.  Wait for them to Connect. Once connected, the Bluetooth icon  on the transmitter close to will turn solid BLUE ; you will hear “Connected” from the earbuds.

4.  Lock them up again - Press & hold the button on the transmitter for about 10 seconds until the   indicator turns PINK for a couple seconds. Then the transmitter and the speaker are LOCKED and will always link to each other once turned on.

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: 

1. 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.
2. 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.

1. REMOVE / DENY the Avantree Device from Samsung TV's "External Device List."
2. 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.

If there is  no sound when you connect the transmitter with your Sony TV via optical cable, please go to the settings of your TV using your Sony TV remote:

1. Press the (Quick Settings) button on the remote control, then select [Settings] — [Display & Sound] — [Audio output] — [Speakers] — [Audio system].

2. If the audio system is not compatible with Dolby Digital or DTS, set [Settings] — [Display & Sound] — [Audio output] — [Digital audio out] to [PCM].

3. Check if the [Digital audio out volume] setting of the TV is at maximum.
Press the (Quick Settings) button on the remote control, then select:
[Settings] — [Display & Sound] — [Audio output] — [Digital audio out volume]

The HT4106 normally supports Dual Link, meaning you can have up to two headphones connected to the transmitter at the same time. You can connect either Avantree headphones as well as Bluetooth headphones from other brands. Both will work. However, there are a few caveats to this:

The HT4106 set, which consists of the Audikast Plus transmitter and the TWS106 earbuds, DOES NOT support dual link with other aptX codec headphones. This means you can not connect an additional aptX headphone to the transmitter.

As a result, we don't recommend to use the HT4106 with two aptX headphones at the same time. TWS earbuds and other small, compact devices often have miniaturized internal antennae which can impact the overall range.

The HT4106 set supports Dual Link with non-aptX headphones such as Airpods, Bose headphones, and other headphones that don't support the aptX codec. However, they don't support most of our headphones, such as the Ace 130 or AS90T, because most of our headphones support the aptX codec.

We are working on a DFU to downgrade the aptX codec to SBC, which will let you freely Dual Link with the HT4106. This FAQ will be updated when it's ready! 

Here are some suggestions for Bluetooth Sets that support Dual Link:

Earbuds

Medley 6018 + Extra Earbuds

HT41866

Audikast Plus Transmitter + 2x TWS116

Headphones

HT41899

In addition, due to the bandwidth constraints of the Bluetooth 5 specification, the 2nd pair of headphones must connect to the HT4106 using the standard Bluetooth SBC (Sub-band codec) only. That's why you may notice that your 2nd pair of headphones has more audio delay than the 4106.

Any other codecs such as aptX, aptX-HD, AAC, LDAC etc. will take up too much bandwidth and may lead to an unstable connection. Please check your headphones' user manual to verify that they only use the SBC codec. If it lists other codecs in addition to SBC, then the headphones are not suitable, leading to the aptX issue listed above.

For more information:

Can I use the earbuds with other devices, and how? 

The Audikast Plus transmitter and the TWS106 earbuds included in the HT4130 set can be used independently. Just make sure that if you use one, you need to turn off the other one. e.g., If you want to pair the transmitter with other headphones, you need to put the TWS106 earbuds in the charging case and close the case. Then enter the transmitter into pairing mode.

Here's how to use the TWS106 earbuds with your Mobile Device instead:

Step 1. Remove earbuds from the case. One earbud will enter PAIRING MODE with the LED flashing BLUE.

Step 2. Go to Bluetooth setting on your mobile device. Search and select "Avantree TWS106R" or "Avantree TWS106L" to connect. After connecting, your device will display "Connected" and the LED will turn off.

Step 3.  Please DO accept the pop-up pairing request from your device. Now you can stream music.

Once paired successfully, they will auto reconnect with the LAST connected device once they powered on. If not, please click "Avantree TWS106R" or "Avantree TWS106L" on your device to manually reconnect.

If you're experiencing intermittent Audio Cuts, please try to resolve the issues with the methods below:

Method 1: Made Sure your Bluetooth headphone / speaker is NOT Multi-Linked

Very often, the intermittent audio cuts out issue is due to the Bluetooth headphone / Speakers are also connected with other devices, e.g. your Cellphone, PC. Please make sure you turn the Bluetooth off on those devices. 

Method 2: Clear Pairing History of BOTH devices and pair them again.( Clear Pairing History is NOT turn on/off.)

• Clear Pairing History / Factory Reset the Headphones / Speakers. (Find the instruction under 'Basic & Advanced Features' under each Avantree product Guide. For Non-Avantree items, please google "Product brand model Clear Pairing History")
  
• Clear Pairing History / Factory Reset the Adapter. (same as above)
• Pair them up again. 

Method 3: Clear away any potential Wireless Interference Devices.

Other wireless devices in the vicinity of the transmitter may negatively affect the range. 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.

If the above is not helpful, please fill the form - Disconnects intermittently/Unstable Connections so we can get in touch and help you to solve the problem. 

One side sound is often caused by one earbud not properly connected to the other. Please try the steps below if this happens.

Solution 1: Soft Reset.

Put both earbuds into the charging case, close the lid, and let it sit for a few minutes. Take them out again and see if the issue gets resolved.

Solution 2: Factory Reset & Re-pairing

Step 1. Put both earbuds back into the charging case.

Step 2. Press & hold both buttons for about 8s, until the LED flashes BLUE 3 times then turns off.

Step 3. Remove both earbuds from the case, keeping them close together so they connect to each other. When complete, the LED on the RIGHT earbud should flash BLUE faster than the LEFT earbud.

Step 4. Earbuds are now reset. Before re-pairing them to your device again, turn on your device's Bluetooth settings:

*Make sure to remove previous Avantree TWS106R and Avantree TWS106L profiles*

Step 5. Put both earbuds close to your device and the RIGHT earbud should be detected first, tap on "Avantree TWS106R" and press OK to allow connection:






DONE. Both earbuds should now be connected and have sound.


If factory resetting doesn't work, please contact us at support@avantree.com immediately.

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:

1. Go to SOUND OUTPUT and change this to OPTICAL / EXTERNAL SPEAKER
2. 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.

LED light flashing on OPT /AUXmeans the transmitter cannot detect a valid optical input signal. Please check your TV audio output settings and connection.

1. Unplug and Re-plug the Optical or AUX cable, make sure it has been plugged tightly. 

2. Check your TV audio output setting like this.

Batch No. or Lot No. is a 4-5 Digit/Alphabet combination (e.g. T22F1, 22B1, or T22J1) printed somewhere on the product. The "somewhere" is usually as follows:

1. on the bottom of the product;

2. on the inside of the Headband, just above the Earcups;

3. on the in-line controls or on a Tag near the 3.5mm AUX Plug;

4. on metal head of the adapter;

Above are some examples that'll give you an idea of what the Batch/Lot Number looks like and where to find them. The print for Batch No. or Lot No. is usually quite small; please consider using a magnifying glass if it's hard to read.
