How Many Listeners Here Listen Mostly With Eyes Closed?

Nope.  Eyes wide open for me.  I like to “see” the performers in a 3D soundstage in my room, but that’s me. 

I sometimes do.  At moments of extreme pleasure, including the most delicious foods (Savery and sweet), it’s worth concentrating on the sensory stimulus!

Eyes open and on guard for surprise attack. 

Most of the time unless I'm playing along with my acoustic guitar. 

Yes!  Almost always at home. Closing my eyes keeps me from “hearing the speakers” with my eyes. The soundstage expands and fills in. Years ago my classical guitar teacher taught me to spend part of a concert not looking at the Performers. This lets you focus exclusively on the music.
