Nice way of posting there ...
I'm aware of issues with standing waves at frequencies of sound when the wavelength is related to a dimension D of the "enclosure" as wavelength = 2*D/n (n=1,2,3,..). I haven't seen as much discussion of standing waves in the "enclosures" made between over-the-ear headphones and our ears. However, I have seen the high-frequency oscillations in headphone frequency response curves and assumed that was the reason. I pretty much agree with this part of your post:
Inside headphones there are also resonant frequencies, usually around 2-3 kHz (look at any headphone frequency graph), and the manufacturers are fighting hard against them. That's why the open back headphones are the best - no reflections to color the sound. See one example below, the rounded triangular shape.
except I think "no reflections (at all)" is too strong a statement to make about open back headphones, "significantly less reflections than closed headphones" is more accurate, but that is sort of a quibble.
However, I stand by the comments in my previous message. I was addressing an "audio myth" that I've seen before and thought you were repeating here:
especially if your room is small, there is no need to worry about bass, it just won't happen
That is the myth that a small room cannot "support" low-bass sound waves of wavelength larger (maybe much larger) than twice the largest room dimension. If one imagines a "small room" with "ideal boundary conditions", like perfectly airtight, rigid walls, I believe that room could not support sound waves of longer wavelength / lower frequency that the fundamental standing wave. Nor could changes in static air pressure (at constant temperature) occur in such a room. Real rooms are not anything like that.
BTW, if offered a chance to do a listening test in a room with perfectly airtight, rigid walls, I would pass
, just personal preference
Because some posters here, like my near-namesake SoNiC67, are good at mis-stating what other people wrote, it would be interesting to see a response that begins "Sonic Icons is scheming to imprison us in an airtight room. With rigid walls." You would hardly need to change my wording at all to have me saying that.
