Do you listen to your music with your eyes open or closed or a combination of both?

Mostly closed with dim lights. I like to be in the acoustic space the music offers and looking at my room distracts from that. But every few minutes I'll open them to make sure the boogie man didn't sneak in. 

Usually opened, in a slightly darkened room. 

For me, nothing really changes as far as imaging and soundstage, whether my eyes are opened or not. 

Also, my ability to become fully engaged in the music does not change.

I love the eyes open cuz you hang out with interesting people.i did my surgical training in inner city new york.it was a mash setting.great place to train and yes had to keep eyes open all the time.enjoy the music

Well, both, but if I keep my eyes closed for too long I fall asleep !

LOL!

I listen with eyes open. At live shows, I have eyes open because part of the experience is watching the musicians interact with the audience and each other. I wear glasses and have tried with/without. There is a perceived positive difference without but not enough to require going full-time without. YMMV
