For me, this party Plugs are inferior to the ER-20 against. Although they are extremely discreet because they almost disappear in the ear, but that is exactly the crux of the matter for me. From time to time, just because the ears rain caused were not quite dry and the hood of the jacket also rubs his ear and shakes, they are slipping. When trying to correct the seat again, I've quickly deal with the problem that the plug will disappear in the ear. I put it without a cord, though could be that which prevents, but the cord is in turn a way yes, accidentally pulling out the hearing protection. There are only 2 fins off which can provide maintenance, the Etymotic ER20 eg have still a more fit so easily and keep. Remove short and replace is no problem with this. If, then only Etymotic ER20.
