Why do the earbuds feel uncomfortable or easy to fall out? / Why does the noise cancellation not seem very effective?
| ****
1. Please wear the earbuds correctly by following the wearing instructions for a comfortable fit and optimal noise cancellation.
2. Noise cancellation in most earbuds primarily targets low-frequency sounds like traffic noise, and it may not fully meet your expectations for reducing higher-frequency voices. You can try foam eartips to enhance overall noise cancellation, but it might somewhat affect comfort.
3. * If the problem persists, please reach out to us at service@myearfun.com
for assistance. We offer an 18-month replacement and refund service. 🙂

| ****
Why do the earbuds stay connected to my phone even after placing them back and closing the case?
| ****
1. Ensure the case is sufficiently charged: If the charging case has no remaining power, placing the earbuds back into the case won’t turn them off.
2. Proper placement and cleanliness: Ensure the earbuds are correctly positioned in the charging case and that the charging contacts are clean. Use a microfiber cloth or similar to clean the contact areas between the case and the earbuds.
3. Please put both earbuds into the charging case to reset them.

Failure to auto- connect with the device after removing from the charging case.
4. Earbuds not pairing.
| ****
1. Remove the protective film in the charging case.
2. Reboot your Bluetooth device. Forget all previous pairing records and disable Bluetooth.

4. Enable Bluetooth on your device and search for “EarFun Free Pro 3” to pair.
5. Test the earbuds with another device (phone, tablet, etc.) to see if the issue persists.
Why is the connection not stable and cuts out intermittently?
| ****
Please check for any objects obstructing the earbuds and the Bluetooth device and avoid any potential radio or WiFi interference. While the earbuds have a maximum range of 49 feet (15m) without obstacles, the actual range may vary depending on usage and the environment.
| ****
Why does the volume of the earbuds decrease after using a period of time?
| ****
1. We kindly suggest you wrap the earbud with your hands, then blow air into the inner filter mesh of the earbud several times to have a try. To provide better sound, the sealing of our headphones is better than that of other headphones when the volume is reduced, perhaps because of the air pressure. When you take it off from your ear, the sound pressure deforms the sound filter mesh.
2. We would suggest you use toothpicks to gently clean out the part near the caps from dust or wax, clean with cotton swab alcohol and then rub them with clean napkins to have a try because accumulated dust or wax on the caps would block out or diminish the volume.
3. If the above suggestions don’t work, we suggest you use a small brush to scrub, rinse the earbuds, then shake water off the earbuds and dry them for 2 days to have a try.
---|---|---
| | We also suggest you try to connect the earbuds to other models of
devices to test whether it is still the same situation.

How to deal with low volume during single-ear calling?
| ****
Note: The left and right earbuds each have two MICs – one for calling and one for noise collection. During a call, only the mic on the main earbud responsible for the call and noise reduction will be activated.
To resolve this, we suggest you use both earbuds together.
If you prefer to use only one earbud for the call, you can place the other earbud in the charging case or turn it off.
What to do if your voice sounds low and unclear to the person on the other end of the call? / What should I do if I hear calls in poor quality? /
What should I do if the other person’s voice is intermittent during a call?
| ****
1. When using only one earbud, keep the other earbud in the charging case.
2. Fully charge your earbuds and reset them.
3. Use ear tips that fit snugly in your ears and position the earbuds correctly for a tight seal. Proper fit ensures better call performance.
4. Select “EarFun Free Pro 3” as the audio output device on your connected device and adjust the volume accordingly.
5. If you experience issues with a specific app, try making a call using your phone to check for any improvements.
6. Test your earbuds with another Bluetooth device in a different environment to compare performance.
7. Try to avoid strong interference environments that may affect the call quality.
ANC:
| Why do noise- canceling mode and ambient sound mode produce white noise in quiet environments?| ****
Almost all earbuds will have a certain amount of white noise when the ambient sound mode and noise reduction mode are turned on in a quiet environment.
We kindly suggest you do not turn on these two modes in a quiet environment.
| ****
Noise cancellation is not working. / Earbuds have noise in ANC.

B. Put both earbuds into the charging case.
C. Keep the charging case open, then press and hold the button on the case for at least 8s until both earbuds flash purple. The earbuds have been successfully reset.

| 1. Experiment with different ear tip sizes to ensure a proper and snug fit. If one earbud feels unstable while the other is stable, try a combination of ear tips, such as medium on the left and large on the right.
2. Verify the perfect positioning of the earbuds. Proper positioning is essential for optimal noise cancellation.
3. Double-check that the active noise cancellation is turned on.
4. Test the earbuds in different environments and with various Bluetooth devices to observe any differences.
Note: In noisy environments and at high volumes, the noise cancellation performance may appear less potent.

I need the microphone mute function.
| ****
Our team listened to your suggestion and created a new version of the firmware that adds the microphone mute function.
Please contact us to get updated firmware of the earbuds and the installation instructions.
Notes:
1. The microphone mute function can only be activated during calls.
2. During a call, please tap the left earbud triple to turn on the mic mute function.
3. When the call ends, the mic mute function will be automatically turned off to ensure that the next call is normal.
When using one earbud, only mono sound is available.
| ****
We are afraid that for Qualcomm chip (aptX series) earbuds, only one side channel sound will be heard when using only one earbud unless aptX is turned off.
Our product team created a special version of the firmware that disable the aptX. Maybe you can contact us to download the file and follow the instructions to update the firmware to try.
Why did the new firmware cancel LE
Audio？
| ****
In LE audio mode, we found that the mobile phone will actively disconnect the earbuds, resulting in no sound from the earbuds. The LE Audio function of our earbuds is fine, but it is a protocol problem on the mobile phone side. In order to solve this problem, we can only disable LE Audio first. After the problem on the mobile phone is resolved, this function will be enabled through a firmware upgrade.
Maybe you can contact us to download the file and follow the instructions to update the firmware to try.
| ****
Why does the adjusted headphones have a whistling sound?
| ****
This may be howling, which is a common phenomenon of noise-canceling headphones. We have tested and found that adjusting the earbuds with a specific strength and a specific angle may trigger this noise. We recommend that you adjust the earbuds gently with light pressure.
---|---|---
Why is there no in- ear detection？
| ****
Due to the difference in the shape of each person’s ear, the in-ear detection may sometimes be insensitive, causing some users to complain, so the new earbuds cancel this function. You could choose the EarFun Air Pro 2 which has the in-ear detection function.
