Hi Friend,
Thanks for choosing EarFun. Sorry for the inconvenience caused.
Could you please send us your order number to check first?
As for the issue you encountered, we kindly suggest you try the below steps.
1 Reboot your phone and reset and reconnect the earbuds.
Step 1: Delete the old connection from the Bluetooth device.
Step 2: Place both earbuds into the charging case.
Step 3: Keep the charging case open, touch and hold the button on each earbud simultaneously for at least 10s until they flash in purple, then earbuds have been reset successfully.
Step 4: Search and reconnect “EarFun Free Pro".
2 A. 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.
B. We would suggest you use toothpicks to gently clean out the part near the caps from dusts or wax, clean with cotton swab alcohol and then rub them with clean napkins to have a try cause accumulated dust or wax on the caps would block out or diminish the volume.
C. If the above suggestions still couldn't solve the issue, we suggest you use the tweezer to remove the filter mesh of the earbuds and then clean the earbuds to check whether the volume will resume to normal.
We also suggest you try to connect the earbuds to other models of devices to test whether it is still the same situation.
If the above methods still could not solve your issues, please email our customer service team via service@myearfun.com or submit the warranty ticket on our official website: https://www.myearfun.com/process-warranty. EarFun provides an 18-month warranty for every product. Your satisfaction is always greatly important to us.
Sincerely,
EarFun Customer Service Team
