Does the one year limited warranty cover sweat damage? If not, how do I get a replacement?

You can even use the same ones if you can dry them out in the sun or on a radiator, also the microwave but make sure not to put the plastic capsules in there.

Silica gel is a great idea. Just don't try to dry the headset in the sun or in the microwave by mistake; I still remember the user who accidentally put their headset in the washing machine 🤭.
