I have quite a serious hearing loss in my left ear since I was attacked with a chair in a pub bar twenty or so years ago. (No Breezy and others - not because someone didn't like my singing !)

When I sing with Linda you'll notice she always stands to my right - otherwise I have difficulty hearing her. I do have a standard "behind the ear" National Health hearing aid, but find it more hindrance than help when I'm singing.

Are the more expensive aids much better ? If so, in what way - louder - clearer - wider frequency responce - smaller ?

Also what sort of prices are we talking ?
