Free Pro 2 left earbud problems

So I purchased Free Pro 2 around last Christmas, 2nd hand cause they werent available in Poland at that time. There were bought on, but unfortunately the receipt is missing (probably discarded during clean up). Been using them since, had No issues.
Quality is amazing, the sound and the product itself and I was beyond happy. 
Yesterday my left earbud became really silent, so I thought alright, time for cleaning. Gave it a good clean with the provided tip and a bit of rubbing alcohol on the outside, got all the small holes clean and all around as Well. 
Unfortunately that did not help, left one is still really silent, and I noticed that when in Noise cancelling mode, when I tap it around, it starts buzzing, like a really bassy buzz, and it stops after a second. Sound quality seems the same (as if it wasnt a speaker-related issue), it just became really quiet compared to the right one.

Is there anything I could try before I reach out to send them for warranty inspection? Should I even bother with warranty if I don't have the receipt? Any firmware update I should have done? 

Greetings, Simon

Hi Simon,


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 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 to our customer service team via or submit the warranty ticket on our official website: EarFun provides 18-month warranty for every product. Your satisfaction is always greatly important to us.
