I purchased the Cala 8 RIE with the size 13 battery. The HAS gave them to me with the tulip domes and a size 1 length receiver wire into the ear canal. (HAS mentioned I may be between a 1 and 2 length.) I tried to wear them for two days and had to give up until I can get back to Costo. They are so uncomfortable to the point of pain in my ear canals on both sides. It is almost as if the metal of the rectangular speaker part that is partially covered by the dome is pressed against my canal because the receiver wire is too short. Or it is the tulip domes that are too large. I was disappointed that the HAS gave me the tulip domes because the stuffed feeling is what I hated so much about my in the canal hearing aids (CIC) of 15 years ago and why I stopped wearing them. The HAS recommended the tulip domes to help amplify the soft tones.
Has anyone experienced this type of problem with the receiver piece that goes in the ear?
Do I really need the tulip domes for my hearing loss?
On a side note, I love the streaming feature of the Cala 8. I watch a lot of educational videos on my iPad and it is fantastic to be able to stream the sound without being attached to a set of earbud headphones.
