Looks like this would be an excellent write up for the ARRL! A recent copy
of QST has done a short article but methinks something a bit more on the
lines of product reviews would be nice.
My current hearing aids, a pair of Resound Forza...sold by Costco..use a
wifi audio interface. The interface has both mic plus plug in for audio
sources. This has been the best for me. The device has a range of about 25
ft with fresh charge..so can grab a cup of coffee while listening to ssb or
cw. To me, the difference between rig speakers and the wifi audio interface
is remarkable!
I have work hearing aids since I was a small boy, and have been hamming for
almost 35 years.
A previous set of hearing aids used telecoils and I used an inductive loop
with an audio interface, but like Gary, this was not good for me. Kept
picking up too much inductive hum from other sources (power supply, light
fixtures, etc) and I could not move around the shack anywhere.
Hope this helps someone.

For those with hearing impairments, the joy of using amateur radio is
diminished if you can’t hear or understand the sounds coming from your
radio.
If you buy or have hearing aids with T-coils (telephone coils) you already
have part of the solution. Hearing aid T-coils normally are used to
inductively couple with the coil in the telephone handset, bypassing the
hearing aid microphone. In many hearing aids the T-coil program has a
separate profile since normal telephone audio frequencies are from 300 to
3000 Hz with a 6 dB per octave rising response providing equal loudness.
With open hearing aids which have a small opening which allows some sounds
to pass unamplified to the eardrum, the use of a headset allows the sounds
from the headset to mix with any sounds produced within the headset as the
result of the T-coil and inductive coupling with the headset. I’ve found
this to not work well for me.
I found J-hooks
(http://www.hearinglosshelp.com/products/earlinks.htm#musicliks) which
provide NO external sound, but do inductively couple to the T-coils of my
hearing aids to produce sounds inside my hearing aides to be the best
solution. I can now copy CW, chase DX, or participate in an AM net (I can
even be net control).
I have NO relationship or interest with
http://www.hearinglosshelp.com/products/earlinks.htm#musicliks except as a
satisfied customer.
Having been through the disappointment as the result of not being able to
hear in a hobby where “you can’t work them if you can’t hear them”, I’m
trying to get the word out to others with problems hearing their radio. If
you know someone with hearing problems, please pass this on to them.
73 ES DX,
