Oh sure. The inside of your ears don't really sweat, but there is still a lot moisture in the ear. Cant you feel it when you take IEMs out after then have been in for a while? When you take out your IEMs there is moisture in them. This moisture slowly start to play havocs with electronics, wire connections, etc. The silica Gel will absorb that moisture very quickly. Sweet!!
Thank you. Didn't know. I don't know if sound degrades over time because of this, or people had their customs die on them. Don't want to take chances. Are there cases specifically for this? Where can I get them?
