A friend of mine told me about the new Olive hearing aids coming from S.
Korea. They are currently being sold only on Indiegogo and one ear is
$139 instead of the multikilobuck jobs. I'm interested to hear how they
work for him. You configure the amplification and response curves using
a smartphone app.

Are you sure of those figures? 30dB is normally only considered mild

I have at least 40dB. across the spectrum, in one ear, and 15dB at
500Hz, degrading to 70dB at 8kHz, in the other, and I'm only classed
as having a moderate loss. These figures are a few years old, so the
current ones are marginally worse.
If you have severe enough loss to need full ear moulds, I think all
modern aids have various options to directly feed the aid with, at
least mono, audio, and some headsets will naturally work with aids
that can be set to an induction loop setting.
Typical options for full stereo, are blank headsets, that just create
an induction field, ear hooks that hook over the ear and create an
induction field, and direct audio input shoes that plug into over the
ear aids, and allow a copper connection to the aid.
For most aids you can get a bluetooth adapter, that you wear on a,
conductive, neck loop. This is generally mono. You can typically
provide a copper audio feed to these, in which case there is no
bluetooth (the near field link uses a different protocol, and at HF,
not SHF), or you can remote bluetooth adapters, which have low
latency, as well as the normal bluetooth adapters, with their high
latency.
The Phonak brand name for this feature is ComPilot. My aids are
Oticon, for which it is ConnectLine.
I think the open fit aids, used by people with, typical, age related,
high frequency loss may be more of a challenge, as they are designed
to pass the low frequencies directly and only amplify the high ones.
