1 Earbuds' microphone stopped working after it fell in a puddle (FIXED)
Hi,
A week ago I accidentally dropped my Samsung Galaxy Buds Pro in a puddle of water. The audio volume was very low and there was some static as well. I then placed the earbuds in a bag of rice and also let it dry out by my windowsill for about 4 days. In terms of audio output the earbuds are perfectly fine now.
However now the earbuds cannot detect my voice anymore, it seems like the microphone was damaged. I've tried making calls and recording audio but it doesn't pick up my voice unless I place the right bud near my mouth which only faintly picks up my voice. It seems to happen on all devices I use it on so it's definitely an issue with the earbuds. Thing is shouldn't microphone have been fine since the earbud is rated as IP68 water-resistant?
Any solutions would be helpful.
Update (02/18/2023)
So I managed to fix them by simply using a toothbrush and pressing the bristles against the microphone holes. Think they were clogged.

Is this a good question?

Rice 🙈 When will people learn rice does not dry out electronics. By leaving it in the miracle substance for four days you've allowed the corrosion process to proceed unhindered. Even if they were under warranty I'd expect Samsung would return them back to you after seeing corrosion inside.
