If the ear is that complicated, how come you know that about it? You don't have any formal education on this front, right? So best to not make up stuff on the fly this way.
As to the product, it is way too expensive relative to engineering that has gone into it. If this is sort of resentment for you, we can't help it. You need to complain to the company to up its game.
There is an annual festival at Oxford University that is 5 or 6 days, with two scientific lectures and two live performances (mostly classical, occasionally jazz) each day. The academic and musical level is world class. It is a lot of fun. Some of the scientific lectures are unrelated to music, but some are related to the perception and experience of sound, sometimes in the context of illness. See for example
http://www.bobrovnikova.com. A memorable event was a lecture by two professors, one being Russell Foster, Professor of Circadian Neuroscience. The programme notes include
"Sunlight is vital to life on Earth; not only does it enable plants to grow it also allows us to see. But it does much more than this including, regulating our body clocks, sleep, seasonal rhythms and even alertness." This was followed by a concert in pitch blackness, at 10pm, with all the windows blacked out, and no external noise. The venue, Holywell Music Room, the oldest concert hall in Europe, has very thick walls and the external noise is usually limited to bicycles. Blindfolds were provided but unnecessary, as I could not see even the shadow of my hand 6 inches in front of me. The performers were a well known jazz trio (piano, percussion, bass), who played for 90 minutes non-stop and were magnificent, especially given they could not see their instruments or each other. It was the most intense musical experience I can recall. There have been lectures, for example, about how the brain function of children is affected by long training from a young age.
The human circadian detector cells that Russell Foster led the discovery and understanding of (
https://en.wikipedia.org/wiki/Russell_Foster) respond very slowly to light conditions, but have a dramatic impact on how our body and brain functions, including our mood. Taking that into account, do a level matched blind test you would have to stay in controlled light conditions for at least a day, and probably only test at one time in the year.
What always gets me from how much we do know is probably how little we really know as a whole about how our brains process sensory perception. Circadian cycles are well known, but the physiology in humans has only been understood for about 20 years.
For example, he explained that it has been known for ages, for example from WWI 100 years ago, that soldiers who were visually blinded and had their eyes removed for cosmetic reasons and replaced with glass eyes, suffered from irregular sleep patterns. By removing their eyes, the functioning non-rod circadian cells were inadvertently removed, hence the effect on sleep and a lot else besides. Those cells are deep in the eye and were only recently discovered.
I find these things endlessly fascinating and I marvel at the breadth and ingenuity of research. One thing that I draw from this is the possible misconception that the ear/brain is a consistent and reliable detection device. Quite the opposite seems to be the case, it varies all the time.
