Airpods pro
today I realised that I put accidentally my AirPods Pro in the washing Maschine. It took me about one hour to see that they have been washed. I dried the a little bit but when I put them both in my ears I hear a hissing noise.
AirPods Pro aren't waterproof.
That said, you're not the only one who accidentally put them in the washing machine. Some users claim that they got them working after a thorough drying period of time (helped by silica gel, dry rice or any moisture absorbing substance).
Your mileage may vary. It's worth to give it a shot. There's no guarantee that it will work, though.
