If that person does not work for Jvc, that test has no barring on my choices. There are countless unique factors to such testing that do not translate to the world outside of their lab. Since I am not using their brain, what importance whatsoever does their testing have to my life experience? none. at. all. On Thu, 13 Oct 2022, Lennart Sorensen wrote:

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.
Those are the numbers from someone actually testing them in a lab: https://reference-audio-analyzer.pro/en/report/hp/jvc-ha-sr44x.php#gsc.tab=0
JVC lists them at 32 ohm and 106 dB/mW so in db/V the measured 113 would be about right for 32 or 33 ohm impedance. It's a bit lower than what JVC claimed but not much.
