I purchased the eargels which was very comfortable and initally stable. Unforunately after a few weeks of infrequent use my ICON would fall out of the eargel and when stored away it invarable fell out and I would have to replace the ICON back into the eargel. So I have returned to using the original ICON rubber piece which although not as comfortable at least stayed in place.
Negative
