Ii use Phonak aids with a double dome type in the canal fitting. However they don’t stay put and slip outwards so I lose the sound. Constantly having to push them back in which sharply increases the sound only for it slowly to diminish again. Only way to maintain a conversation is to keep my finger pushed to my ear canal. This gets quite sore too. Anyone had similar issues and overcome them?
First point of call should be your audiologist. Problem could be the size of the domes, the length of the tube, the absence of a retention cord, or even the shape and structure of your ear.
