In this video we are fixing our JBL TWS earbuds (in this case the waterproof JBL Reflect Mini NC). The problem is that one of the earbuds is a lot quieter than the other.
When looking into the hole of both ear-tips, then we can see that the one, which is quieter, has a blockage of dirt, grime and earwax, blocking the path of the sound. Especially the grid at the very outside is clogged.
We are soaking the earbuds in a little amount of rubbing alcohol in order to resolve the blockage. Leave the earbud in the solution for at least half an hour. Make sure not to dunk the entire earbud, especially in case your earbud model is not considered waterproof.
