One earbud has gone quieter than the other

Hi Alex,

Thanks for choosing EarFun. Sorry for the inconvenience caused. 

As for the issue you encountered, we kindly suggest you try the below steps.

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 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.

C. If the above suggestions don’t work, we suggest you use a small brush to scrub, rinse the earbuds, then shake the 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.

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
