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.

auditory processing is not a hearing disorder. it is not what I hear, but how sound, verbal sound is neurologically managed from the brain down. 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. https://www.bestbuy.ca/en-ca/product/jbl-quantum-100-gaming-headset-black/14...
