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.

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. 

Step 1: Download the Avantree Center APP
1.Download and install the  Avantree Center  APP on your phone. (right-click then select 'open in new tab')

• For iPhone, download "Avantree Center" from the App Store

Press "Button Settings" to adjust what the buttons on your device do. There are a variety of functions you can use.

Step 5: Exit the App and reconnect 

If you are using the headphones with your phone, you're good to go! If not, you will need to disconnect them from your phone. Go into your phone's Bluetooth settings and click on the device name to disconnect them from your phone. After that, connect the headphones to your PC, TV transmitter, or other device by following the pairing instructions for that device. The changes that you made in the app will follow to your new device. Now, you should be good to go!

If you connected the Audikast Plus Transmitter to your TV via either 3.5mm AUX or RCA, you should be able to adjust the volume using your TV remote.

On the other hand, if you're using a Digital Optical (SPDIF/TOSLINK) connection, your TV remote control cannot adjust the volume level.

In this case, please use either the volume buttons on the Audikast Plus Transmitter or the volume control on the headphones to adjust volume. 

On the transmitter, you can adjust the volume by clicking the "+" and "-" buttons. 

Here's how to adjust the volume on the earbuds.

To INCREASE Volume: Double-click the main button on the R Earbud.

To DECREASE Volume: Double-click the main button on the L Earbud.

If you have any questions, please contact us at support@avantree.com with more details. 

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 < 64Ω

If 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. Please email to support@avantree.com

Please note: the Ace T40 can only pair with SBC codec headphones. We recommend using our NB16 and TWS116 to use as the 2nd pair. For more information, you can refer to the following:

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.

Will I still have audio delay when using Avantree transmitters?

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).

If you encounter issues mentioned above, please also contact Sennheiser's customer support and let them know.

First, please check if the earbuds are blocked by any debris, which is often caused by earwax. Use a suitable soft-bristled brush to gently clean any potential blockages. This is the most common reason for this issue with the earbuds.

Secondly, this may cause either by a disconnection between the Left and Right earbuds. Here's the fix:

Disconnection

First, check to see if the Left and Right earbuds are disconnected from each other. In this case, the R earbud is still connected to the device, and you can hear audio from R earbud. However, the L earbud is disconnected with the R earbud, so there's no audio from the L earbud.

We can tell if they're disconnected by looking at the LED indicators. Here's what the LEDs will look like:

R earbud - no light (When connected to your device, the LED will turn off)
L earbud - flashing blue rapidlly.

If you've confirmed that the Left and Right earbuds are disconnected from each other, here's what to do next:

Please restart the earbuds to recover their connection with your phone or other device you want to use with.

Step 1. Put both earbuds back into the charging case and close the case cover.

Step 2. Open the case and the earbuds will try to recover their connection between each other.

Step 3. They may reconnect with your device automatically. If not, please follow the 'Use with a Mobile Device' to pair them with your device again.

Note: Before you pair again, please delete or forget Avantree Ace 130 on the Bluetooth list of the device.

Step 4. If step 3 failed, please try to reset/clear the pairing history of the Avantree Ace 130 earbuds by following this link - How to factory reset / clear pairing history of Ace 130? 

If this didn't fix your problem, kindly contact support@avantree.com for further help.

Are you finding that your Ace 130 earbuds have low bass or a tinny sound? In order to fix this, you will need to use the Avantree Center App to adjust the equalizer settings of the Ace 130. You can pick an equalizer mode that increases the amount of bass on the earbuds. Once the appropriate equalizer mode is set, the changes will be saved, and will follow the earbuds to whichever device you connect it to.

Step 5: Exit the App and reconnect 

If you are using the Ace 130 with your phone, you're good to go! If not, you will need to disconnect the earbuds from your phone. Go into your phone's Bluetooth settings and click on Avantree Ace 130 to disconnect them from your phone. After that, connect the earbuds to your PC, TV transmitter, or other device by following the pairing instructions for that device. The changes that you made in the app will follow to your new device. Now, you should be good to go!

Please feel free to contact support@avantree.com with any further questions about this product or the above DFU procedure.

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]

No, there is no AC adapter in the box. The reasons are:

1. It is recommended to power the Avantree TV Transmitter from your TV USB, so it will be on / off with TV easily;

2. Most people have many AC adapters from cellphone and others. For environmentally friendly consideration, we will not include an un-necessary accessory.

3. FREE AC adapters can be provided upon request within first 30 days of purchase for product over 50 dollars.

The compatible power adapter needs to be with output of 5V 500mA - 2A.

Extra AC adapter can also be purchased here - https://avantree.com/usb-charger

To use your 5.1 Surround Sound system at the same time, all you need to do is to get the Avantree Orbit as a Bluetooth transmitter, taking advantage of its passthrough function as well as the Surround Sound support

If you want to achieve 7.1 Surround Soundand you have an AV Receiver with HDMI Zone 2 output, then you need to add an extra HDMI Audio Extractor to extract the optical audio signal for the TV headphone / Transmitter.

Here is the diagram of the reference connections:

RCA Zone 2 on AVR is not recommended because it normally cannot be in sync with the main zone. 

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.

The HT4130 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 HT4130 set, which consists of the Audikast Plus transmitter and the Ace 130 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 HT4130 with two aptX headphones at the same time. Ace (TWS) earbuds and other small, compact devices often have miniaturized internal antennae which can impact the overall range.

The HT4130 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.

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 HT4130 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 4130.

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 Ace 130 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 Ace 130 earbuds in the charging case and close the case. Then enter the transmitter into pairing mode.

Here's how to use the Ace 130 earbuds with your Mobile Device instead:

Step 1: Refer to the following link and Enter Pairing Mode on the Avantree Ace 130.

How to get Ace 130 into Bluetooth Pairing Mode?

Step 2: Connect/Pair the Headphone to Bluetooth on Your Device.

On your device, locate the Bluetooth settings and make sure that Bluetooth is turned on. Find the headphone  “Avantree Ace 130” and select it to pair them up.

Once connected, the LED on the headphones will occasionally flash BLUE and the headphones will show as connected on your device. The voice prompt will say "Connected" to indicate connection.

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.

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?

Note: The latency for FastStream is almost the same as aptX Low Latency, but the audio quality of aptX Low Latency is better.

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

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.

Your pacemaker is designed to work properly around most appliances and tools. However, electromagnetic interference (EMI) from headphones and earbuds may affect how your pacemaker works. These effects are usually temporary. Still, we recommend following these guidelines to stay safe.

Anything that transmits Bluetooth or with a magnet inside cannot be used closer than 6'' (15 cm) to a pacemaker. All of our Headphones, Speakers, and Earbuds, as well as all of our Bluetooth products fall under this category, and must not be placed very close to your pacemaker. Normal usage of our headphones and earbuds - wearing them in or over your ears - is completely safe.

The Takeaway: It’s safe to use headphones and earbuds with your pacemaker, but you should not drape them around your neck or store them in a breast or other shirt pocket - as that would put them too close to your pacemaker. Normal usage should bear no problems.

As you may know, earbuds get dirty pretty easily... Earwax, dust, water etc. can all do damage to them. Uncleaned earbuds may lead to...

• Music sounding muddy or muffled
• Different volume on the two earbuds
• Abnormaly low volume / tinny sound after using for a period of time

Daily maintaince can effectively eliminate such problems.

• Before wearing the earbuds, make sure to clean the inner side of the ear.
• Always wear and use earbuds in dry condition.
• After using the earbuds, wipe the inside of the earbud tip with a soft and dry towel to remove dust, earwax, or oil from your skin.

If you're already experiencing different volume levels between the two earbuds, please try to follow the following steps to clean them out:

(These apply to all Avantree earbuds, but the following uses the NB18 as an example.)

1. Materials you'll need: a cotton swab and dried brush (if you can't find the black cleaning brush, a toothbrush can work instead.)

2. Take off the earbud tips from the earbuds smoothly. Do not detach the earbud tip from the earbud excessively as it may tear.

3. Use a cotton swab and dried brush to remove any debris and foreign materials.

4. If foreign substance is still present, try brushing the earbuds again to dislodge the remainder.

5. After you finish cleaning, please assemble the earbud tip back to the earbud properly. Cover the latch at the bottom of the earbud with the earbud tip like below.

Please note: Do not use liquid like alcohol or soapy water for cleaning earbuds as some of our earbuds are not alcohol-proof or soapy-waterproof.

If the problem still exists after cleaning the earbuds, please contact support@avantree.com for help.
