A drop of water fell on my XS earpiece.

Hello, I want to ask. If I dropped literally one drop of water on my earpiece on iPhone XS, will it cause damage. After I showered, I went and hold my phone and a drop of water fell on the earpiece. After that, I immediately wiped it off with a piece of cloth.

Even though it seems like nothing happened, I can’t keep myself from worrying, will it damage my earpiece. Is the water resistant spec strong enough to protect my earpiece from a drop of water?

Your response will be much appreciated
