Accidentally Washed My AirPods Pro 2 – Should I Be Worried?

I accidentally left my AirPods Pro 2 in my pants and put them through the washing machine for an hour. They then stayed inside the machine overnight.

Surprisingly, they still work fine after taking them out.

Should I be concerned about their performance in the long run? For example, could this affect the sound quality, transparency mode, noise cancellation, or battery life?

Would this kind of damage significantly impact these features?
