*properly designed* estats do not have issues with dust or humidity. Stax drivers for example are all fully sealed and are safe from environmental conditions as long as the dust covers (on the drivers themselves) are intact.Can't say what the monoprice estat is like. IIRC the koss estat is not sealed so it has dust problems.

Yes you should keep all electrostatic headphones covered when not in use. One member used a shower cap to keep dust out when not in use. I use either the case or a gallon sized zip lock bag.
