Another aid to think about is the Siemens Music. It is my understanding
they are now available in BTE's. They include the Wide Dynamic Range
compression, optional volume control, 2 programs, and nice people to work
with. Siemens is a tiny little company with 300 some thousand people
working for them, and have been known to be a little creative when it
comes to innovative technology. They are comparable to the ReSound,
however, they have an adjustable compression ratio, and kneepoint.
Otherwise, the other two you mentioned are good solutions as well.
