Regretably my experience with Oticon has not been great. For a start I suffer badly from Menieres and it is known that the Cochlea in one of the ears is damaged. I dont get a clear hearing of words through my system and it is impossible to hear in speech when there is other background noses( traffic washing machine etc). The first time I was back at my consultant he put my aids back to base so to speak as I could not get the volume loud enough. About 1 month ago hearing in my left HA stopped working-was sent back and came back to me to say the ear mould was clogged with ear wax Once they were cleaned out the was a much better respose in my hearing needs and from them on all has been fine
