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.
" remember that one over the top review when jonathan skull announced to the world he removed his eyeglasses when listening and voila, everything sounded better and different!!! 🤣😂"
Noting that the reflective qualities of Michael Fremer's record collection could be responsible for his listening environment, I don't see that a pair of glasses being regarded as a reflective surface only inches from our receptors [ears] wouldn't make a meaningful difference as well. I wonder if the engineers who designed the famous Neumann KU-100 microphone in the shape of a human head ever considered a special model wearing eyeglasses ?
Try it even if you don't regularly wear eyeglasses and if you don't hear a difference may I suggest a visit to a hearing specialist ? It definitely makes a difference !
