Microphone audio unusable in one ear Samsung Galaxy Buds Plus
My left earbud has really bad audio. The right earbud sounds fine but the left one isn't as loud and it has a hissing sound similar to TV static or a high pitched squeal.
I'm pretty sure this is because of the buildup in the tiny holes (which I assume are for the microphones) on each ear bud getting clogged with debris and gunk (maybe I broke the mic by inserting toothpicks in too far too many times) and that these have been drenched in water and I have not dried them fast enough with a heat gun.
I have used 99% Isopropyl Alcohol but nothing seems to get the left earbud's mic to work properly again.
Any idea on where to go from here? I have not decided to open them up but I have the tools to do so and that might be the only way.
Thanks for your time for reading this
