Provide a link.
The jvc ha-44x over ear extreme explotive headphones, have a sensitivity
of 106 db.
and a mono impedance of 32m...so says the link from JVC I have had
bookmarked since 2014..at least.
I need no calculator to make safe determinations for my body.
so, please share the link from the jvc website, documenting your claim
regarding the model ha-s44x.

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.
