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?

Other than the indicator, if you're using a Headphone/Speaker that has voice prompt (i.e. it says "welcome to Avantree" when you power it on,) it'll say "Pairing" when it's in pairing mode.

If it's flashing RED & BLUE yet you can't connect it, please refer to the steps below.

Step 1: Reboot it and try again.

Yes, the good o' soft reset often resolves the issue. Please give it a go. Please also try rebooting your Phone/Computer.
If you still can't get them to connect, please proceed to step 2.

Step 2: Try it Somewhere Else.

Bluetooth connection can often be interfered with by other wireless connections such as WiFi Router, TV streaming device, or even another Bluetooth device. Please either move them away or try to do the pairing somewhere else.

If you are still unable to pair, continue to Step 3.

Step 3: Factory Reset.

If you find that the earbuds are not secure and comfortable enough, but none of the ear tips fit you, you may go to the below link to purchase a pair of extra small ear tips. 

https://avantree.com/extra-small-xs-size-ear-tips 

Both left and right headset have built-in Mic.

When they used as pairs, the right side Mic will automatically stop working,just the left side Mic works.

When they use as single one, each side Mic works well.

Bluetooth headphones / earbuds can be used with Bluetooth-enabled smart TV directly. If your TV does not have built-in Bluetooth, then you will need a Bluetooth audio transmitter to use with your Bluetooth Headphones for TV. Or you can simply get a Bluetooth headphone TV set instead.

Note:
1. TV Bluetooth does not support aptX Low Latency and you might detect slight audio delay via Bluetooth.
2. TV Bluetooth does not normally offer a great operating range. Good quality Bluetooth audio transmitter will support longer operating range.
3. TV Bluetooth normally mute the TV speaker as well as all other TV audio outputs. So for users perfer TV speaker OR soundbar working at the same time, please use external Bluetooth transmitter instead of TV Bluetooth. 

If no above concerns, use your Bluetooth headphones with TV Bluetooth is the easiest solution for you.

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.

Are you listening to music and chatting at the same time? Are you playing games with your friends and talking on Discord at the same time? If you're using the headphones in this way, the sound quality will be bad because your headphones do not support the FastStream codec.

FastStream is a type of Bluetooth codec. When you connect a headphone/headset that supports FastStream to an adapter that also supports FastStream, you'll be able to get 16-bit Stereo Quality voice chats - much better than the Mono quality you've been getting through your own headphones. Not only that, but you won't experience a drop in sound quality when gaming and chatting at the same time.

* Important Note*

To take advantage of the better performance of the FastStream codec, the other Bluetooth device must support the same codec. If the other device only supports aptX or SBC, these codecs will be used instead of FastStream.

Some of our products like the 90P-ENC, 90B, 130T and 1060 do not support this, as either the headphones or the dongle do not support FastStream. So we recommend the AS90+DG80 to customers who want to listen to music or play games while chatting at the same time. This set of products is perfect for in-game chatting and VOIP calls on PC.

FastStream Headphones we recommend: AS90, AH6B, Aria Pro, NB16.

FastStream Dongles we recommend: DG80, Leaf (DG50), DG60, and C81.

If you're using the Avantree C81 on PS4/PS5, you could use the included 3.5mm mic to get stereo sound quality while talking - How to use the 3.5mm microphone？

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

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.

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.

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.
