Ed,

I understand your more severe hearing loss, but I was responding IN PART 
to many others on the list with much less several loss than you, and can 
use RXEQ to solve their own problems, at least until their hearing loss 
progresses.

As a Fellow of the Audio Engineering Society,  I also understand the 
issues with headphones fitting hearing aids, just as I also understand 
the DIFFERENCES between hearing loss and hearing aids.

Etymotic Research, one of the major mfrs of signal processing for 
hearing aids of the type you wear, has long been a supporter of the 
Chicago Section of the AES, and their engineers are active in that 
section and made excellent technical presentations to the section. Until 
I moved to CA in 2006, I was an active member of that Section. Nearly 10 
years ago, my colleague Bob Schulein (who was the designer of the Shure 
SM57 and SM58 and by then joined Etymotic) presented his work on the 
development of directional mics for hearing aids.

It's really good that you have raised these issues in detail, because 
the physical design of a hearing aid has major impact on whether it CAN 
work with headphones -- that is, where are the sensors, and are there 
headphones that can comfortably be worn with them in place. This is an 
important question that any of us must resolve when BUYING a hearing aid.

I suspect that any good headphones that WILL fit will work reasonably 
well if they are also sufficiently comfortable.  That was the reason for 
my comments responding to a question (don't remember if it was yours) 
about comfort and the CM500s. These ARE circumaural phones, so they 
might fit you.  Ditto for the Sony 7506.
