That oscillation means there is probably distortion going down there because the tone is lower than the cans can comfortably reproduce. It probably extends upwards a bit too.
That's actually uncommon but not abnormal. And you're conclusion about the latter case seems sensible.UPDATE:
I tried out this site, https://www.szynalski.com/tone-generator/.
I officially hear actual tone around 16-17 hertz. I hear sound below that but it sounds like an oscillation, like listening through a fan (am I hearing just the mechanism of the driver itself working?). Going below 16 hertz there is absolutely no discernible tone.
Expressing volume in terms of percentage doesn't really tell us much; although, it does tell us you're probably pluggin your headphones directly into the front of the PC. Have you tried using the port in the back? Magnetic fields from PC components add a lot of noise to the front I/O.Interesting. I'll go ahead and believe that it's distortion then. But hearing ever so slightly below 20 hertz isn't bad I'd say...it's lower than what is practically needed probably.
I tried to see how high I could hear, I stopped hearing anything after around 17,900 or so. That's probably pretty standard. I read that after one's teenage years high frequency hearing tends to drop off a bit.
