the db/nw number is perfectly understandable for me.
Further any sensitivity less than 105 is personally out of the question
for me.
Honestly, while I appreciate your ideas, clearly my hope for general
information is turning into my need to defend a medically documented
processing injury..I get enough burden to society talk for the blindness
to have no interest defending what history teaches me is safe.
For the record, there is, or was, a fine cbc nature of things about
neuroplasticity drawing from the book, "the brain's way of healing."
Some of the featured doctors have been my own at some point over the
years.

Consumer gear works just fine.
By way of example.
I have a pair of Sony mdr-xb50ap headphones which would be just wonderful..
if the impedance were higher.
I had a pair of JvC ha-s44x headphones, honestly almost anything in their
extreme explotive line would be terrific..if it also had a microphone.
Which is why I asked here.
Well looking up the specs of those JVC headphones I see impedance of
33.4 ohm and sensitivity of 113.1 dB/V (decibel per volt I guess).
I think that must be the 32 and 100 to 110 you were mentioning. Of course
most headphones if they give specs are in dB/mW which is apparently
meaningless since you have to account for the impedence to compare them.
I found a calculator page that says the JVC at 113.1 dB/V at 33.4 ohm
would be 98.34 dB/mW.
I found the JBL Quantum 100, which is listed as 32 ohm, 96 dB/mW,
which the calculator says is 111 dB/V so just about identical to the
JVC headphones. They are listed on JBL's website at $60 canadian.
3.5mm jack, no USB or bluetooth or any of that other
modern stuff. Bestbuy currently lists it on sale for $40.
