A system and method for use in iontophoretic anesthesia of a tympanic membrane are disclosed. The system generally includes an earplug and an electrode device. The earplug includes at least one sealing member for sealing the earplug in an ear canal. The sealing member includes microholes which vent fluid above a certain pressure threshold. A headset may connect the earplug to a second earplug. The method involves using the system on a human or animal subject.
