I don't know any of the technical stuff regarding my hearing aids, but I
do get the phantom aids after use. Actually I often have to check
because in or out -- my ears feel full.
After showering I use Q-tips to dry my ears and dry the outside grooves
and valleys. By the time I get dressed my ears are dry enough for the
aids. I've been using these visible-in-the-ear aids for 1 1/2 years.
Hope you get more help from others.. RJE
