I recall posting a reference to a thread about "simple tweaks" to our systems and mentioned one of the easiest tweaks for people who normally wear glasses was to simply remove them ! Apparently the idea is still met with derision judging by this post in the current thread about reviewer’s listening rooms.
You just can’t take anything a reviewer says seriously.
We have no idea whether their hearing isn’t damaged or irregular in some way.
We don’t know the acoustics of their rooms.
We also have no idea whether they know anything about the way the human hearing system works. Or whether they even care.
A fair bit of sound, particularly at volume is heard via bone conduction slightly before our brains can register it.
Removing a pair of glasses is bound to affect the way sound is perceived by the listener and not least because of the lack of reflections.
Since vision competes with hearing for attention at all times music will always tend to sound clearer in a darkened room/ late at night or with ones eyes shut.
I usually notice a slight increase in the precise placement of voices and instruments immediately when I close my eyes.
Give your brain less to do and it will usually do it better.
