My hearing aids have blue tooth but require an interface to use it with
my iphone. The interface is a wireless remote control for the hearing
aids and came with a very small thing that plugs into audio sources via
a mini-phone plug. That sends the sound via BT to the remote and on to
my hearing aids. Haven't used it much but that might work better than a
headset. I didn't note any latency.
I have a K3, KX3, and new IC9700 which all provide ext audio. The issue
for lengthy use is the remote rechargeable battery life is short (maybe
two hours).
Note to Jim: Yes I realize its audio feedback in the CM500. Have no
problem using my Sony MVR-V600 headphones or my Bose noise-cancelling
headset. Suggestion that I wear headphones without hearing aids does
not work for me. Hearing loss is not just a factor of amplitude (I
cannot hear tones above 4-KHz). Loss is >100 dB. My hearing aids
provide 22 channel digital processing and I still need closed captioning
watching TV.
Digital modes are best for doing weak-signal ham radio as I can see the
computer FB.

Slight topic change, apologies.
Has anyone used rx audio via Bluetooth into their hearing aids? Any issues?
I was hoping the K4 would have BT audio, but it doesn't.? So the next
best option would be to send the sound card audio to BT in a computer,
linked to the aids or headset...? I don't have my K4 yet, so it's a guess.

Apparently my hearing aid gain is so high the CM500 provided feedback
to the hearing aid mics - I have two with my OTE (over the ear)
hearing aids.
That's acoustic interaction of the earphones with your aids, and
depends on the placement of the mics in the aids. Mics for the aids
are picking up their own amplified sound, because the acoustic space
around the ear is modified by the presence of the earphones. In sound
systems, we call that feedback. It makes sense that different
headphones would interact differently with aids, depending on the
construction of both.
My XYL uses aids where the mics are outside the ear. She doesn't use
headphones when she's wearing them.
