Of course in addition to the above aids mentioned, there are in-ear ones which have mics, same as the behind the ear ones - they aren't inductive.

This type vary in size - the really tiny ones are invisible apart from a tiny pin thingy which you use to take them out, switch 'em on etc. I have a middling size pair which comes with 3 or more programs for different situations, e2e wireless which links left & right, and a remote control.

In-ear aids do seem to be less prone to feedback with headphones, but you do have to fiddle around a bit to seat the phones. I too find Sennheiser HD280s & similar are good.

My biggest problem with aids is that they are a bit "toppy" - although mine are programmable the nice lady audiologist can never seem to quite fix this problem, even when using a dedicated music program. I imagine it's inherent as you probably can't get a hifi frequency response out of a tiny transducer. But I hope I'm wrong....

Best of luck with 'em Les, you will soon find that more people than you think use aids! Very handy when you forget the spare batteries. And beware showers and swimming pools!
