First, make sure that the headphones are on. To activate the Active Noise Cancelling (ANC), slide the ANC switch toward "ANC". The LED on the switch will light up GREEN to indicate that ANC is on. 
When not in use, please remember to turn the ANC function off to prevent battery drainage.
We do not recommend activating ANC when using the headphones with a wire (not Bluetooth).

                    
How it Works:
Our Active Noise Canceling (ANC) headphones "cancel out" background noise by emitting its own sound wave that counters and reduces the volume of unwanted sounds.

Note:
ANC works best for reducing consistent low frequency background noise. It is ineffective at reducing inconsistent or sudden bursts of sound (shouting, car horns, etc.) In quiet environments, you may be able to hear some noise because the ANC microphone may be unable to detect defined background noises.

Conducting a factory reset on the headphones will clear all past pairing data and restore the default settings for the product. You may want to reset your headphones if you have trouble pairing them with your devices.

Step 1: Turn on the Headphones.
Locate the power switch and push it to the middle. The LED will turn BLUE.
                

Step 2: Reset the Headphones.
Press and hold the volume + and - buttons simultaneously for about 5 seconds until the LED turns PINK, indicating that the headphones have reset. The headphones should then go into pairing mode and the LED will alternate between flashing RED & BLUE. The voice prompt will also say "Pairing". You are now free to pair the headphones with any device! 
          

NOTE: the factory reset will NOT work if the headphones are in use. Please make sure to hang up any calls and pause any music before attempting to factory reset, and start the process with the headphones powered off.

If your headphone is not responding, you've tried plugging the charging cable directly to the headphone to charge it for 2 minutes to no avail, and this resetting guide can not solve it, either, please fill in the following RMA verification Form for replacement:

Method 1: Clear Pairing History of your headphone and pair them again (Clear Pairing History is NOT turn on/off).

Method 2: Clear away any potential Wireless Interference Devices.
Other wireless devices in the vicinity of this set may negatively affect the working 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 source of interference away; that ought to clear the problem.

Method 3: Avoid Physical Objects.
Walls, solid materials, or even human bodies can all become "obstacles" that negatively affect the Bluetooth device's range. Please try clearing the space between the dongle and headphone, and see if that helps.

Method 4: Test with other devices (if possible).

Unfortunately, the buttons on the Headphones CANNOT be used to pick up phone calls or mute on your Computer. 

However, if your headphone is connected to your phone and you're using Skype or Zoom on your phone, the buttons will work properly.

This is a general issue among Bluetooth headsets; our engineers are working hard to find a solution that can work around this issue.

When you'd like to MUTE the Microphone however, most of our Bluetooth headsets have independent physical Microphone Mute buttons on the Detachable Microphone.

Headsets that have the physical mute button: Aria (AS90), Aria Pro (AS90P), Aria Podio (AS90T), Aria Me (AS90TA), Audition Mic (AS9M), DG59M, C519M.

If you still have questions, please feel free to contact us at support@avantree.com.

Check Point 1: Have you Connected/Paired it Properly?
Check on your device Bluetooth device list, it should say "Connected" on the menu. If not, please try to pair it to your device again.

Check Point 2: Have you been Switching between APPs?
Sometimes when you're listening to music and a call comes in, the Headphones/Speaker can have issues switching back-n-forth... this is a common Bluetooth issue and happens to every Bluetooth Headphone/Speaker. 
Please choose the headphone/speaker again (if applicable) or reboot the headphone/speaker and pair them up again.

Check Point 3: Have you Charged the Headphone/Speaker?
This might seem like a simple solution but when the device is low on battery, a wide variety of issues may occur. Please make sure that it has sufficient battery level.

If you've checked everything above but still no sound, please try the methods below.

Method 1: Try it on a Different Device.
If you have another phone, another laptop etc... try to connect the Headphone/Speaker to it and see if it works on the other device. 
If yes, it's probably something to do with the settings on your original device, please try again.
If no, please contact us for support, you may have a faulty unit.

Method 2 (For Laptops/Computers): Check the Audio Settings.
For Windows, go into Sound Settings and Sound Control Panel. For Mac, go into Sound Preferences.
Make sure that the Headphone/Speaker you'd like to use has been selected as the Audio Output/Input device.
If you're using a Meeting Software such as Skype or Zoom, you may need to go into the app itself and adjust the settings in there as well.

Method 3: Factory Reset.
If none of the methods above work, please factory reset the Headphone/Speaker and pair again. Please remember to delete the Avantree device from the paired Bluetooth device list on our sound source device, before attempting to pair again.

If factory reset still can't get it to work or if you have any more questions or need further assistance, feel free to contact us at support@avantree.com

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.

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？

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

4. on metal head of the adapter;

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.
