The only problem with that is you don't hold that rectangular case up to your ear you put the small earpiece in your ear.

Good point and why would anyone talk into a hearing device? If I were trying to hear things over an old time hearing type aid I would be as quiet as possible so that I could hear what it was that I was having it in my ear to hear in the first place, not carrying on a conversation with myself.
